| #7263 | OpenMPI+Open MP: The available threads decreased over iterations | trbahb252 | 2019-12-28 (6y8m) | - | Close (unsupported version) (reported on unknown (2019, likely 4.0.x)): User reported omp_get_max_threads dropping each iteration in a hybrid MPI+OpenMP loop. No version, code or reply. Most likely binding/OpenMP runtime usage rather than an Open MPI bug. No activity since 2019 and nothing ties it to v5.0.x. |
| #7217 | MPI_Comm_split crashes with Portals4 | ptaffet | 2019-12-03 (6y9m) | - | Close (wrong repo) (reported on 4.0.1): MPI_Comm_split crashed with a ct_check assertion in the Portals4 UDP-mode library. Maintainer tkordenbrock identified it as a Portals4 reference implementation bug and opened Portals4/portals4#82 (still open). No Open MPI change was identified. |
| #7165 | Run openmpi on docker containers on different hosts | uray10 | 2019-11-14 (6y10m) | - | Close (unsupported version) (reported on 2.1.1): User could not get orted to start across Docker containers on separate GCP VMs with 2.1.1; admits it is mainly a Docker networking setup question. No comments since 2019-11. Support question, not a bug; launch is PRRTE-based in v5.0.x. |
| #7164 | Unable to run mpiexec in an MPI initialized environment | EFanZh | 2019-11-14 (6y10m) | - | Close (won't fix) (reported on 4.0.2): posix_spawn of mpiexec after MPI_Init exits with status 256 (worked in 2.1.1). ggouaillardet (2019-11) said this is expected, suggested MPI_Comm_spawn with MPI_Info for non-MPI apps. No further activity. |
| #7143 | OSHMEM: SHPCLMOVE returns incorrect error code for 2 cases | sssharka | 2019-11-05 (6y10m) | - | Keep (reported on 4.0.1): SHPCLMOVE returns -2 instead of -4 (block already freed) and -5 (not at block start). v5.0.x oshmem/shmem/fortran/shpclmove_f.c still maps any shrealloc failure to -2 and never returns -4 or -5. Unchanged; no comments. |
| #7130 | [btl_tcp_component.c:966:mca_btl_tcp_component_create_listen] bind() failed: no port available in the range | wuxun-zhang | 2019-10-31 (6y10m) | question | Close (unsupported version) (reported on 4.0.2): User restricted btl_tcp to 8445-8456 for a firewall. netstat showed mpirun itself listening on 8445-8455, so the TCP BTL could not bind. Advice given (check ports, use if_include). Last reply 2020-12. This is a setup issue, not a bug, and ORTE was removed in v5. |
| #7123 | Detect when running in a containerized environment | jjhursey | 2019-10-29 (6y10m) | enhancement, help wanted | Close (wrong repo) (reported on master-2019): jjhursey RFE: have mpirun detect containers (for example Singularity) and adjust defaults such as plm_rsh_chdir via an orted schizo component. No comments since 2019. ORTE is gone in v5.0.0, and schizo and mpirun behavior now live in PRRTE (openpmix/prrte). No container detection exists there today. |
| #7120 | SSH not execute when some node is same with the host performs mpirun | sui-hs | 2019-10-29 (6y10m) | - | Close (unsupported version) (reported on 3.1.4): 3.1.4 user wanted mpirun to ssh to its own node so .bashrc sets PATH for the script. Maintainers said mpirun never ssh-es locally, so set PATH before running. User setup issue, no reply since 2019-10. orte/ is absent in v5.0.x. |
| #7110 | Error in ompi_io_ompio_calcl_aggregator() running netcdf testsuite on 32-bit hardware | opoplawski | 2019-10-26 (6y10m) | bug | Close (unsupported version) (reported on 4.0.2): The netcdf testsuite failed on i686/arm with ompi_io_ompio_calcl_aggregator rank_index(-2). edgargabriel fixed the 32-bit aggregator calculation (master ea1355beae, v4.0.x backport 02da54c174 in v4.0.3). The reporter confirmed the fix (2019-11) but the issue was never closed. |
| #7106 | mpiexec not allowing more cpus per process in more than one node (master or slave) | rafaeltiveron | 2019-10-24 (6y11m) | - | Close (won't fix) (reported on 4.0.x): User asked to give one process 28-40 cpus spanning two 24-slot nodes. rhc54 (2019-11) replied it cannot work: cpus-per-proc larger than the node is rejected even with overload-allowed. A process cannot span nodes. No further activity. |
| #7091 | Wrong values for MPI_Datatype with armflang | alinask | 2019-10-15 (6y11m) | - | Close (unsupported version) (reported on 4.0.x-2019): With armflang/flang, mpi_f08 constants like MPI_INTEGER came out wrong because the weak symbol was not bound at runtime (a compiler bug, reported to Arm). ggouaillardet reworked the f08 constants in #7105 (merged 2019), which is in v5.0.0 and v4.0.3. Last comment in 2021 asked about closing. |
| #7090 | Is it possible to use different OFI mtl for inter- and intra-node transfers? | mszpindler | 2019-10-15 (6y11m) | question | Close (stale) (reported on master-2019): User with custom libfabric provider lacking loopback asked to use different providers intra/inter-node. jsquyres: CM/MTL uses a single provider; OB1/BTL allows per-peer transports. Answered 2019-10; v5.0.x has opal/mca/btl/ofi for that model. No further activity. |
| #7088 | How to reduce Open MPI's memory footprint? | mkre | 2019-10-14 (6y11m) | - | Close (unsupported version) (reported on 3.1.3): User compared memory footprint vs Platform MPI. Advice given: disable oob/ud (rhc54), UCX UD/fifo knobs (brminich), ob1+vader single-node (hjelmn). Last activity Nov 2019. oob/ud, ORTE and openib are gone in v5.0.x; no actionable ompi bug. |
| #7085 | illegal node name | leeQT | 2019-10-11 (6y11m) | - | Close (unsupported version) (reported on 4.0.2): 4.0.2 mpirun rejected hostname with underscore (ORTE regex). ggouaillardet asked about uname -n in 2019, no reply. orte/ is absent in v5.0.x and the error text is not in the v5 tree. If it happens on v5, file it against openpmix/prrte. |
| #7044 | v3.1.x hangs at startup when openib BTL provider is active since commit 8be0a233c87d | lnussbaum | 2019-10-05 (6y11m) | - | Close (unsupported version) (reported on 3.1.x): Bisected hang to 8be0a233c8 on v3.1.x with -mca btl openib,self. No comments since 2019. btl/openib absent in v5.0.x and main (cat-file), and v3.1.x is EOL. |
| #7042 | Improve map-by, rank-by, bind-to docs | gpaulsen | 2019-10-04 (6y11m) | - | Close (fixed) (reported on 4.0.x): Request for better map-by, rank-by and bind-to docs. jjhursey rewrote the PRRTE docs in prrte PR 773, and in v5.0.x mpirun is prterun. docs/man-openmpi/man1/mpirun.1.rst in v5.0.x has a Mapping, Ranking, and Binding: Oh My! section plus a policies section. Last activity 2021-08. |
| #6982 | User's PMIx call fails after MPI_Init + UCX/HCOLL | angainor | 2019-09-17 (7y) | bug | Close (wrong repo) (reported on 4.0.1, 4.0.2 (PMIx 3.1.4)): User PMIx_Get of a key posted after MPI_Init fails with -46 across nodes. angainor reduced it to a PMIx-only sequence (Put, Fence, Put, Get); rhc54 (2020-01) traced it to the PMIx server answering not-found instead of deferring, test added to prrte #294. Not an ompi bug; pmix issue 1427 closed. |
| #6960 | IPv4 vs. IPv6 issues | mkre | 2019-09-05 (7y) | Target: main | Close (unsupported version) (reported on 3.1.3, 4.0.1, 4.0.2rc2): --enable-ipv6 builds aborted in ORTE oob_tcp_listener on IPv4-only nodes. rhc54 fixed it and cherry-picked to 3.1.x/4.0.x, but the user still saw 'No network interfaces' for OOB in 4.0.2rc2 and it was reopened (2020-01). Last activity 2020-02. The ORTE OOB code is gone in v5.0.x. |
| #6916 | Error using MPI_Comm_connect/MPI_Comm_accept | nuriallv | 2019-08-20 (7y1m) | question | Close (unsupported version) (reported on master-2019 (ORTE)): MPI_Comm_connect/accept between two separate mpiruns failed with ORTE_ERROR_LOG Not supported. rhc54 answered that a rendezvous server (ompi-server) or a PRRTE DVM is needed (2019-09). No follow-up. ORTE was removed in v5.0.0. Any remaining cross-mpirun connect issue belongs to prrte/openpmix. |
| #6896 | .dylib warning from dlopen() for libcuda on Linux | cparrott73 | 2019-08-12 (7y1m) | question | Close (unsupported version) (reported on 3.1.3): The warning listed failed dlopen attempts of libcuda.dylib on Linux nodes without GPUs. It came from opal/mca/common/cuda, which is gone in v5.0.x. The v5.0.x accelerator/cuda component links libcuda via accelerator_cuda_LIBS. Last activity 2019-08. |
| #6878 | Linking separate executables with MPI_open_port sharing port information in a text file | edwardsmith999 | 2019-08-07 (7y1m) | - | Close (unsupported version) (reported on 2.0.1, 4.0.1): Two separately launched mpiexec jobs hang in Comm_connect/accept using a port name shared via a file; ompi-server attempt failed with ORTE errors. No replies. v5.0.x docs/launching-apps/unusual.rst: start prte --report-uri and launch both jobs with mpiexec --dvm file:uri to use connect/accept. |
| #6876 | mca/coll: segfault on v4.0.x | amaslenn | 2019-08-07 (7y1m) | - | Close (unsupported version) (reported on 4.0.x-2019): Regression from #6806: Ialltoallw segfaulted in ompi_coll_base_retain_datatypes_w (mpich nbicalltoallw). ggouaillardet flagged it as a likely duplicate of #6870 (closed). Fixed on master by #6880 and on v4.0.x by #6889, first in v4.0.2. |
| #6868 | UCX (SW) RMA Atomics Performance | devreal | 2019-08-06 (7y1m) | - | Close (unsupported version) (reported on 4.0.x): High MPI_Accumulate latency with osc/ucx on 4.0.x, caused by an accumulate lock (remote CAS) per op. devreal proposed acc_single_intrinsic and skipping the lock under an exclusive lock, merged as PR #6980 (907f4e196a, 427d4bd226, 73a183408f), first in v5.0.0. |
| #6847 | --use-hwthread-cpus changes behaviour of program | Niken-physics | 2019-07-26 (7y1m) | - | Close (unsupported version) (reported on 3.x (Cygwin)): Barrier appeared to hang with --use-hwthread-cpus on a 2-core i3 under Cygwin. awlauria (2021, v4.0.6) found it completes, just much slower (oversubscribed polling); suggested closing as working as expected. mpirun is PRRTE in v5. Last activity 2021-06. |
| #6831 | Coding Style | guserav | 2019-07-22 (7y2m) | - | Close (fixed) (reported on master-2019): 2019 discussion about tab/whitespace policy and CI checks (tabs-only vs clang-format). Last activity 2019-07. Project later adopted clang-format: .clang-format exists in v5.0.x and main, and opal was reformatted in f067a89832 (first tag v5.0.0). |
| #6829 | Error running HPL on Cori | nuriallv | 2019-07-19 (7y2m) | bug | Close (unsupported version) (reported on master-2019): HPL on Cori with btl/ugni failed with SOURCE_SSID AT_PF_INV on an RDMA read. hppritcha said it pointed to a bad source buffer (2019-07), then no follow-up. Cori is retired, Cray XC/uGNI hardware is effectively gone, and ugni was dropped after v5.0.x. |
| #6818 | mpirun segfault in mpi_comm_connect/accept on multimachine jobs | zack-hable | 2019-07-15 (7y2m) | - | Close (unsupported version) (reported on 4.0.1, 3.1.4, 2.1.1): Multi-node server and client jobs rendezvousing through ompi-server made the client's mpirun segfault on 4.0.1 and hang on 3.x. A 2023 maintainer follow-up got no reply. orte/ and orte-server are gone in v5.0.x; connect/accept now goes through PRRTE/PMIx. Any remaining problem belongs in prrte. |
| #6777 | UCX seemingly causing Python MPI tests to fail with Open MPI v4.0.5 | jsquyres | 2019-06-26 (7y2m) | bug, Target: v4.0.x | Close (unsupported version) (reported on 4.0.1 / 4.0.5): mpi4py RMA CompareAndSwap/FetchAndOp on 1-, 2- and 16-byte types failed with osc/ucx because UCX lacks those atomic sizes. e215eff43d (2020) restricted UCX atomics to 32/64-bit; v5.0.x checks ompi_osc_base_is_atomic_size_supported and falls back. The 2023 comment is an unrelated segfault. |
| #6768 | hwloc symbol conflicts | markalle | 2019-06-19 (7y3m) | question | Close (stale) (reported on master-2019): hwloc_* symbols in libhcoll clashed with external hwloc 2 used by OMPI. jsquyres/rhc argued external hwloc should be the system one; jladd-mlnx said fixed in HCOLL (2019-07). Proposal to rename libhwloc for OMPI never pursued. Last activity 2019-07. |
| #6728 | shmem.h uses C++ <complex> type for C++, but standard uses _Complex from <complex.h> | sam6258 | 2019-05-31 (7y3m) | bug, question, Target: main | Keep (reported on master-2019, 3.0.x-4.0.x): In C++, OSHMEM_COMPLEX_TYPE is std::complex<T>, so Sandia C++ tests calling shmem_complex*_to_all with _Complex fail to compile. hppritcha asked Mellanox about plans in 2021 with no answer. oshmem/include/shmem.h.in is unchanged in v5.0.x and main. |
| #6719 | Openmpi conflicting with wifi on macOS | nbengdahl | 2019-05-30 (7y3m) | question | Close (unsupported version) (reported on 4.0.0 / 4.0.2): ParFlow on macOS failed in MPI_Comm_split with MPI_ERR_ARG when on some enterprise WiFi networks and worked with WiFi off. Still seen on 4.0.2 (last comment Nov 2019). No small reproducer and never triaged. The runtime/OOB was replaced in v5.0.0, and nothing shows it persists. |
| #6710 | MPI.COMM_SELF.Spawn() error | connorourke | 2019-05-29 (7y3m) | - | Needs check (reported on 3.1.4): mpi4py loop of COMM_SELF.Spawn fails after ~3276 spawns (proc on host unknown, ompi_dpm_dyn_init Unreachable), also on one node. No maintainer reply since 2019-06. Test: run the toy script (or a C loop of MPI_Comm_spawn+disconnect) for >5000 iterations on v5.0.x; close if it passes. |
| #6494 | Reproducible Linear Algebra through posit-enabled MPI reductions | Ravenwater | 2019-03-17 (7y6m) | feature request | Close (stale) (reported on n/a (feature request 2019)): Request for collaboration to add posit-based MPI reduction ops. bosilca offered to take a look and the requester followed up by email on 2019-03-19. No PR or activity since then. |
| #6464 | DDT shows message queues with pml ob1 but not with ucx and yalla. | bartoldeman | 2019-03-05 (7y6m) | bug, good first issue | Keep (reported on 2.1.1, 3.1.x): DDT message queues are empty with pml ucx because the msgq DLL walks mca_pml_base_send/recv_requests, which only ob1/cm populate. On v5.0.x and main, libompi_dbg_msgq still reads those lists and pml/ucx still does not use them (grep). Proposed opt-in MCA param was never done. yalla is gone. |
| #6447 | horovod distributed failed run in k8s with kube-router | wangqiaoshi | 2019-03-04 (7y6m) | - | Close (unsupported version) (reported on 3.1.2): Horovod on k8s hung and the TCP BTL dropped inbound connections because the source IP did not match known peer IPs. Similar to closed issue 6103 (flannel). Another user confirmed that disabling ip-masquerade fixes it. The only later activity is a 2024 question. Not an Open MPI defect. |
| #6422 | Add a test to verify that next_cid works after unbalanced communicator creation | abouteiller | 2019-02-22 (7y7m) | enhancement, test | Close (stale) (reported on master-2019): bosilca asked for a regression test for next_cid after unbalanced communicator creation, following PR #6417 (cart/graph create skipped next_cid). The fix merged in 2019 and first shipped in v5.0.0. No comments or activity on the test request since. Tests like this would live in ompi-tests. |
| #6390 | MPI_Bcast hangs with version 4.0.0 when opal_progress_set_event_flag is set. | iassiour | 2019-02-15 (7y7m) | - | Close (unsupported version) (reported on 4.0.0): Bcast hang when app calls internal opal_progress_set_event_flag(1) to stop busy polling. ggouaillardet said it is not for end users, suggested mpi_yield_when_idle and --mca btl ^vader, which the reporter confirmed worked (2019-02-22). mpi_yield_when_idle exists in v5.0.x. |
| #6366 | Unexpected behavior of DataType.getSize in Java | malinkallen | 2019-02-07 (7y7m) | question | Keep (reported on 3.1.3): Java Datatype.getSize/getExtent count elements, not bytes, which conflicts with byte-based createResized/struct. Options discussed: fix the docs, add byte APIs, or switch to bytes in v5. Last activity was a 2021 question about v5.0.0. v5.0.x Datatype.java still returns getSize(handle)/baseSize. |
| #6243 | PGF90-S-0081-Illegal selector - KIND value must be non-negative with PGI 18.10 and OpenMPI master (v4.0.x) | azrael417 | 2019-01-06 (7y8m) | - | Close (unsupported version) (reported on master-2019 (pre-4.0)): PGI 18.10 Fortran KIND error, first from hand-edited wrapper files mixing gfortran/pgfortran (unsupported), then a memkind header clash in native PGI build (workaround --with-memkind=no). Last activity 2019-01, no full error log posted. PGI 18.x obsolete; no report on v5.0.x. |
| #6242 | Memory Leaks in pmix4x & mpool | ax3l | 2019-01-06 (7y8m) | - | Close (unsupported version) (reported on master-2019-01): ASan found leaks in embedded pmix4x query_cbfunc and mpool_hugepage_find_hugepages. Gilles fixed the hugepage one in 78fffa25f2 (Refs 6242, first in v5.0.0). opal/mca/pmix/pmix4x is gone in v5.0.x and PMIx leaks belong to openpmix. Last activity 2019-01. |
| #6240 | TCP: unexpected process identifier in connect_ack | abouteiller | 2019-01-05 (7y8m) | bug, Target: main | Needs check (reported on master-2019): TCP BTL deadlock with 'received unexpected process identifier' on multi-rail hosts with non-routable ifaces (virbr0, docker0); if_include worked around it. PR #7134 (reachable pairing, v5.0.0) meant to fix; mkre 2020 still hung on master without excluding docker0. Test: v5.0.x mpirun -mca btl tcp,self IMB pingpong across 2+ nodes with docker0/virbr0 up, no if_include/exclude. |

No comments. v4.0.0+ and v5.0.x opal_progress_events guards opal_event_loop with an atomic swap lock (bdbb853461), absent in v3.1.4. |
| #6143 | When using libtool to compile against Open MPI, libopen-pal and libopen-rte are explicitly linked in | jsquyres | 2018-12-01 (7y9m) | bug | Keep (reported on 3.1.x / 4.0.x (master-2018)): Libtool .la files make apps like HDF5 link libopen-pal/libopen-rte directly, which breaks cross-version runs. The Debian link_all_deplibs patch and dropping .la files were discussed with no resolution. libopen-rte is gone in v5, but libopen-pal 70:3:30 (so.40) became 80:0:0 (so.80) while libmpi stayed .40. |
| #6113 | Not enough slots when upgrading from 2.0.2 to 4.0.0 | iljah | 2018-11-26 (7y9m) | - | Close (unsupported version) (reported on 4.0.0): 4.0.0 limits procs to physical cores (not hwthreads); user could not make oversubscribe the default via mca-params.conf. Explained by bgoglin/rhc54 2018-11. v4.0.1 changelog: fix for ORTE rmaps_base_oversubscribe MCA param. v5.0.x docs/mca.rst documents the PRRTE equivalent. |
| #6060 | v3.1.3 Non-fatal "make all" warnings | JonathanNStewart | 2018-11-08 (7y10m) | - | Close (unsupported version) (reported on 3.1.3): List of compiler warnings from a macOS 10.13 build of 3.1.3: pragma pack, va_start with bool, libevent unused functions, deprecated syscall, empty libs, const char basename. No comments. 3970b06134 fixed the va_start warnings (in v5.0.0), and sharedfp now uses opal_basename. |
| #6001 | CUDA-aware MPI broken after calling MPI_Bcast | masterleinad | 2018-10-30 (7y10m) | - | Close (unsupported version) (reported on 2.1.5, 3.1.3): Wrong data after MPI_Bcast with 2 GPUs, later segfault in UCX 1.4 ucp_dt_pack due to cudaMalloc interception (UCX_MEMTYPE_CACHE=n worked around it). Akshay could not reproduce with 2.1.3/3.1.0. Last activity 2018-12 ping. Old UCX memtype-cache problem. |
| #5976 | Failed to convert worker name to MPI index: ps:0:0 | qyyy | 2018-10-26 (7y10m) | - | Close (wrong repo) (reported on 3.1.2): The TF parameter-server benchmark aborted in tensorflow/contrib/mpi/mpi_utils.h with Failed to convert worker name to MPI index. The ps and worker processes were started separately rather than under one mpirun. The only reply (2020) says the same. No Open MPI defect was shown. |

Awaiting code since 2018, v4.0.x label dropped 2021. Instead use-mpi-tkr was deleted in main/v6.0.x (dc82f61977, Jan 2025); v5.0.x is a bugfix branch. |
| #5946 | Running osu_acc_latency errors out with 3.1.2 | Akshay-Venkatesh | 2018-10-17 (7y11m) | question | Close (unsupported version) (reported on 3.1.2): osu_acc_latency segv in mca_btl_openib_get via osc/rdma on 3.1.2 (worked in 3.1.0). Devs said unrelated to btl/uct; no further triage since 2018. opal/mca/btl/openib does not exist in v5.0.x; one-sided on IB now uses osc/ucx. |
| #5902 | TCP BTL progress thread segv's | jsquyres | 2018-10-11 (7y11m) | bug | Needs check (reported on master-2018): Segv in ~60% of runs at MPI_Finalize with btl tcp,self and btl_tcp_progress_thread=1 (2 nodes x16); suspected TCP progress thread still running after component dlclose. Maintainers pinged, no fix identified; option still exists in v5.0.x. Test: loop that config on v5.0.x/main, check for finalize segv. |
| #5885 | PML fallback not selected if explicit MCA components specified | mkre | 2018-10-10 (7y11m) | - | Close (unsupported version) (reported on 3.1.2): User expected '-mca pml cm,yalla -mca mtl psm' to fall back to yalla when psm is unusable; got no pml component opened. Both components are gone in v5.0.x. No maintainer response; no activity since 2018-10. Re-file with v5 components (e.g. pml cm,ucx) if fallback still fails. |
| #5839 | Compilation against HCOLL<=3.0 fails | mkre | 2018-10-04 (7y11m) | - | Close (unsupported version) (reported on 3.1.2, 4.0.3): coll/hcoll fails to compile against HCOLL 3.0 because it lacks coll_allgatherv/alltoallv/gatherv/igatherv. Mellanox acked 2018, still seen on 4.0.3 (2020), no fix. v5.0.x still uses those members unconditionally, but HCOLL 3.0 is a ~2014 release nobody ships; hcoll dropped from main/v6.0.x (87335ba8cd). |
| #5818 | TCP BTL: problems when there are multiple IP interfaces in the same subnet | jsquyres | 2018-10-01 (7y11m) | bug, Target: v4.1.x | Close (unsupported version) (reported on master-2018 (3.x/4.x)): TCP BTL dropped inbound connections when an interface has multiple IPs in one subnet. bwbarrett 457f058e73 (Refs #5818) publishes the module address and bind()s to it; in v5.0.x. #3035 race fixed separately in 4.x. reox 2024-01: 5.0.1 works where 4.1.4 failed. |
| #5808 | --MCA flag does not activate btl framework to work with specified components (TCP/IB) | abeltre1 | 2018-09-29 (7y11m) | question | Close (unsupported version) (reported on 3.1.2): User saw same latency for --mca btl tcp vs openib because pml cm/mtl mxm was selected. ggouaillardet explained pml ob1 plus btl self and if_include usage (2018-10-01). Both mtl/mxm and btl/openib are absent from v5.0.x. |
| #5763 | Performance issues with memory/patcher | mkre | 2018-09-24 (8y) | question, State-Awaiting developer information | Close (unsupported version) (reported on 3.1.2): User saw a 1-5% slowdown from memory/patcher on FDR IB with 3.1.2 and asked whether disabling it was safe. Disabling it worked for them (2018-10). No developer reply. The patcher still exists in v5.0.x, but openib, its main registration-cache consumer then, was removed in v5.0.0 (8de786f5a4). |
| #5599 | BML (and BTL) framework(s) initialized even when they are not used | jsquyres | 2018-08-25 (8y) | question | Close (stale) (reported on master-2018): Asked why BML (and thus BTL) framework opens even with pml ucx. bwbarrett: BML used to init ompi_proc_t pieces, more than an if statement. v5.0.x still lists bml in instance.c framework deps (init stays lazy via ob1/osc rdma). No activity since 2018-09. |
| #5478 | Segfault in MPI_Barrier | elliottslaughter | 2018-07-25 (8y1m) | question | Close (unsupported version) (reported on 3.0.1, 2.1.1): Intermittent MPI_Barrier segfault or unreachable-peer errors from btl_openib_connect_udcm when launched with srun on IB EDR. mpirun worked. Maintainers never root-caused it, last activity 2018-08. The openib BTL is gone in v5.0.x (cat-file confirms), and IB now goes through UCX. |
| #5206 | Java bindings vs mpool/memkind | ggouaillardet | 2018-05-31 (8y3m) | bug, java bindings | Needs check (reported on master-2018): Java tests crash at exit because libmemkind pthread key destructor runs after the component is dlclosed; workaround --mca mpool ^memkind or --disable-dlopen. ggouaillardet sent a PoC fix upstream to memkind 2018-06. Test: v5.0.x built with --enable-mpi-java and memkind, run a Java hello, check exit crash. |
| #5172 | Need a way to limit vma tree size (specifically for rgpusm if that's possible) | Akshay-Venkatesh | 2018-05-15 (8y4m) | enhancement, question, State-Awaiting developer information | Needs check (reported on 2.0.x, 3.0.x): Stale cuIpcMemHandles in rgpusm pile up on cudaMalloc/Isend/Irecv/cudaFree loops; asked for vma tree size knobs. hjelmn agreed 2018-06, jsquyres pinged 2018-09, no follow-up. v5.0.x still has smcuda+rgpusm (rcache_size_limit, leave_pinned, empty_cache) but vma_tree_items params are gone (38d9b10db8). Test: run the loop on v5.0.x with pml ob1 btl smcuda over 2 GPUs and watch GPU memory. |
| #4963 | TCP/BTL multi-NIC still hangs | rhc54 | 2018-03-25 (8y5m) | bug, Target: main | Close (unsupported version) (reported on master-2018): The TCP BTL tried to connect over an unroutable NIC pairing on asymmetric multi-subnet nodes and hung. btl_tcp_if_include with a CIDR worked around it. bwbarrett took it but no fix landed on this issue. The 2019 comment is about openib udcm (unrelated). TCP pairing now uses opal_reachable plus bipartite graph matching, in v5.0.0. |
| #4866 | Error running MPI hello-world with IB on 16 machines (2 or more threads per node) | junjieqian | 2018-02-27 (8y6m) | - | Close (unsupported version) (reported on 1.10.3, 3.0.0): Segfault in mca_btl_openib during MPI_Init at 16 nodes with mixed IB/RoCE mlx5 ports; workaround btl_openib_if_exclude. Last comment 2018-03-01. opal/mca/btl/openib is absent from v5.0.x and main. |
| #4845 | Document binding behavior (especially w.r.t. threads) | jsquyres | 2018-02-20 (8y7m) | documentation | Close (fixed) (reported on master-2018): Action item from 2018 webex: document default binding and its effect on progress threads, and how to change it. Discussion of binding progress threads went nowhere. v5.0.x docs/man-openmpi/man1/mpirun.1.rst documents the defaults and says threaded apps should use bind-to none or multiple PEs; affinity.rst covers threads. |

Fragments from two threads appeared to overlap. Last activity 2018-04. To decide, run the attached reproducer on v5.0.x with --mca pml ob1 --mca btl self,tcp,smcuda and CUDA buffers. |
| #4596 | generalized request in FORTRAN exits with error | AboorvaDevarajan | 2017-12-11 (8y9m) | - | Close (unsupported version) (reported on master-2017): The Fortran generalized-request query left status.MPI_ERROR uninitialized, which caused a spurious MPI_ERR_TRUNCATE in MPI_Wait. PRs #4597 and #6416 were closed unmerged. markalle's PR #8578 now does Status_c2f before f_query and sets MPI_ERROR only on failure. That code is in v5.0.x ompi/request/grequest.c. |
| #4507 | romio meaning of fp_ind for location within a file view | markalle | 2017-11-15 (8y10m) | - | Close (wrong repo) (reported on master-2017 (romio314)): markalle: ROMIO's zero-length LB/UB entries in flattened types confuse fp_ind handling in ADIOI_GEN_WriteStrided_naive. The repro needs a source hack routing NFS to the naive path. No replies besides a cc (2017). romio341 in v5.0.x still keeps LB/UB markers, but ompio is the default and v6.0.x/main have no ROMIO. |
| #4423 | Improve OPAL_CHECK_PACKAGE | jsquyres | 2017-10-30 (8y10m) | enhancement, help wanted | Close (stale) (reported on master-2017): Idea from PR 4413 to make OPAL_CHECK_PACKAGE guarantee which library a -L path resolves to. There were no comments or work on it. Brian Barrett retired OPAL_CHECK_PACKAGE in 8489370f14 (first in v5.0.0); package checks now use OAC_CHECK_PACKAGE from config/oac. |
| #4282 | memory/patcher selected also when all tests fail | matzeri | 2017-09-29 (8y11m) | bug | Close (unsupported version) (reported on 2.1.2): memory/patcher was selected on Cygwin even though its configure probes failed, which broke the build. Gilles' patch from the thread became d19a8351c8, first in v4.0.0. v5.0.x memory_patcher_component.c has the SYS_munmap guards. Last activity 2017-10. |

Rest was design discussion on hostname storage. Last activity 2017-09. |
| #4099 | Huge number of leaked symbols when compiling with icc | jsquyres | 2017-08-16 (9y1m) | bug | Close (unsupported version) (reported on master-2017 (3.0.x)): make check symbol-name checker flagged many leaked symbols with icc 17. Consensus: false positives from compiler/linked libs; markalle removed the test (PR #4119 merged Aug 2017). No nmcheck in v5.0.x; icc itself is retired. Last activity Aug 2017. |
| #4034 | NAG Fortran compiler -rpath configuration error | nncarlson | 2017-08-06 (9y1m) | - | Close (unsupported version) (reported on 2.1.1): mpifort wrapper passed -Wl,-rpath that NAG forwarded to gcc. ggouaillardet said fix was in v3.0.0rc2 and backported via PR #2092; reporter verified both on 2017-08-15. PR #2092 merged 2017-08-30, contained in v2.1.2+. |
| #4032 | NAG Fortran compiler does not recognize the -pthread option | nncarlson | 2017-08-05 (9y1m) | - | Close (unsupported version) (reported on 2.1.1): NAG Fortran rejected -pthread when linking libmpi_usempi. Reporter confirmed v3.0.0rc2 and PR #2092 patch on 2.1.1 both fix it (2017-08-15). v5.0.x autogen.pl patches ltmain.sh for nagfor -pthread via config/ltmain_nag_pthread.diff. |
| #4019 | opal_bitmap test is always passed | Sergei-Lebedev | 2017-08-04 (9y1m) | - | Close (fixed) (reported on 2.1.1): test/class/opal_bitmap.c main() ignored test_finalize() and always returned 0. Only a 2024 ping since. main and v6.0.x now return test_finalize() (PR #13976, first in v6.0.0rc1). v5.0.x still returns 0 but it is test-only code; not worth a backport. |
| #3954 | Fortran/C PMPI profiling wrappers | markalle | 2017-07-24 (9y2m) | - | Close (stale) (reported on 2.1.x/master-2017): markalle proposed an MCA/configure switch so C profiling wrappers also catch Fortran calls. jsquyres, ggouaillardet and bosilca preferred current behavior (Fortran wrappers in Fortran); outline agreed but never implemented. v5.0.x mpif-h send_f.c still calls PMPI_Send. Last activity Sep 2017. |
| #3781 | MPI_Gather Performance Issue (ompi_coll_base_gather_intra_linear_sync) | hunsa | 2017-06-28 (9y2m) | - | Close (unsupported version) (reported on 2.1.1): The first MPI_Gather call with the linear_sync algorithm took 7s at 512 ranks. bosilca identified lazy connection establishment as the cause; the reporter confirmed that mpi_preconnect_all removed it. bosilca also answered when linear_sync is beneficial. No open defect; last activity 2017-06. |
| #3769 | Segv in new monitoring coll | jsquyres | 2017-06-27 (9y2m) | bug | Close (unsupported version) (reported on master-2017): Cisco MTT segv in new coll/monitoring even when not enabled; bosilca reproduced and pushed f8ffec926e same day (2017-06-27), issue never closed. git tag --contains gives v3.1.0 as first release. |
| #3612 | XL Fortran Compiler F08 Bindings broken for OpenSHMEM | jjhursey | 2017-05-30 (9y3m) | bug, help wanted | Keep (reported on master-2017, 3.0.0rc1, master-2021): xlf defaults to no-underscore Fortran symbols, and oshmem/shmem/fortran only emits _, __ and _f names. jjhursey found the fix sprawling. In 2021 on master he confirmed it again and showed the documented FC='xlf -qextname' workaround also fails to link. docs/release-notes/compilers.rst in v5.0.x/main still documents it and links #3612. |
| #3470 | Extend SLURM integration | rhc54 | 2017-05-08 (9y4m) | enhancement | Close (wrong repo) (reported on master-2017): Request to have ORTE slurm RAS read ThreadsPerCore so Cray native slurm hwthread slot counts are not treated as cores. hjelmn explained need in 2017; no further activity. ORTE removed in v5.0.0 (orte/ absent in v5.0.x); slurm allocation handling is in PRRTE. |
| #3438 | Problem with MPI I/O with np>1 and large filetypes | jsquyres | 2017-04-29 (9y4m) | bug, question | Close (unsupported version) (reported on 2.1.x/master-2017): MPI I/O with np>1 and very large filetypes crashed. ggouaillardet found a datatype bug (ompio) and a ROMIO bug; edgargabriel confirmed the fix. bosilca's datatype rework went to master and bwbarrett pulled it into 3.0. Last activity May 2017. |
| #3394 | Nightly snapshot tarball filename problematic for RPMs | jsquyres | 2017-04-21 (9y5m) | question | Close (stale) (reported on 2.0.x nightly (2017)): User building RPMs from nightly tarballs hit RPM rejecting '-' in Version. bwbarrett said the name could change, but nobody did it (last comment 2017-04). Nightly tarballs aren't meant for RPM packaging, and the nightly scripts have since moved out of this repo (2ac8f75e0c). |
| #3357 | --enable-script-wrapper-compilers and oshmem build failures | bwbarrett | 2017-04-14 (9y5m) | bug | Keep (reported on master-2017): --enable-script-wrapper-compilers breaks the oshmem wrappers. On v5.0.x and main, oshmem/tools/wrappers/Makefile.am still always symlinks shmemcc/oshcc etc. to opal_wrapper, but opal_wrapper is not built when script wrappers are on (opal/tools/wrappers/Makefile.am), so the links dangle. No comments. |
| #3182 | MPI_ALLOC_MEM slowness with CP2K application | jsquyres | 2017-03-16 (9y6m) | bug, performance | Close (unsupported version) (reported on 2.0.x): CP2K spent most of its time in MPI_ALLOC_MEM/FREE_MEM because 2.0.x registered buffers with every mpool on each alloc and free. c53c0d84f4 (first in v2.1.0) removed that. In v5.0.x mca_mpool_base_alloc only allocates from an mpool, with no rcache registration. Deferred in 2017 with no activity since. |
| #3176 | Adjust rcache framework to allow hooking madvise properly | jsquyres | 2017-03-15 (9y6m) | enhancement | Close (fixed) (reported on master-2017 (2.x)): Placeholder to rework rcache so madvise(2) can be hooked safely (it was disabled in 3caeda21dc). hjelmn added b6bf3f4d95 rcache deadlock reduction and 813762334e memory/patcher: hook madvise (2017-08); v5.0.x patcher patches madvise. No comments. |
| #3145 | Getting Segmentation fault when run OpenFoam with openib on aarch64 | rishards | 2017-03-12 (9y6m) | bug, question | Close (unsupported version) (reported on master-2017): OpenFOAM segv in btl_openib_handle_incoming on aarch64 (corrupted hdr->tag, credit issues); ARM folks pinged in 2017, no follow-up. btl/openib does not exist in v5.0.x or main (cat-file). Use UCX on v5. |
| #2985 | wrong endianness for "external32" representation | tgastine | 2017-02-15 (9y7m) | - | Close (unsupported version) (reported on 2.0.x): OMPIO wrote native-endian data for the external32 datarep. edgargabriel said support was incomplete; ROMIO fixes were backported in #2996/#2997. OMPIO external32 read/write came in PR #6697 (2019), which is in v5.0.0 and in v4.1.0 via the ompio resync ff130e7a9c. |
| #2984 | Something odd about cuda.h configury checking | jsquyres | 2017-02-15 (9y7m) | - | Close (unsupported version) (reported on master-2017): Siegmar's config.log showed cuda.h usability failures; sjeaugey confirmed those lines were hwloc's own configure, OMPI CUDA support was detected. Only a wish to teach embedded hwloc about CUDA paths remained. v5 uses hwloc 2.x (bundled or external). Last activity 2017-02. |

Last reply in 2016 promised more info, but none came. romio341 in v5.0.x keeps the HAVE_DECL_PWRITE==0 fallback, which modern glibc does not trigger. 3rd-party/romio341 is absent from v6.0.x and main. |
| #2389 | MPI_Lookup_name fails if process for name has exited | pietern | 2016-11-08 (9y10m) | bug | Close (unsupported version) (reported on 2.0.1): MPI_Lookup_name via standalone orte-server returned stale zeroed entries after publisher exited (PACK-PMIX-VALUE unsupported type).

Related --with-mpi-moduledir exists since v5.0.4 (3095d2dde0) but does not do multi-compiler builds. No owner for years. |
| #2025 | can opal_progress() call opal_progress()? (test hanging in MPI_COMM_DUP) | jsquyres | 2016-08-27 (10y) | bug | Keep (reported on master-2016, 3.0.x, 3.1.x): Started as a keyval test hang, then became MT/idup CID deadlocks. bosilca confirmed overlapping MPI_Comm_idup (or idup+Ibcast) is valid MPI and can deadlock. ggouaillardet's PoC patch was never merged (last activity 2019). In v5.0.x/main, ompi_comm_nextcid_nb only uses the extended-CID path when comm==NULL, so idup keeps the old algorithm. Repro: two back-to-back MPI_Comm_idup on COMM_WORLD with 4 ranks. |
| #1764 | Handling of datatypes with initial gaps in certain in-place collectives | hiliev | 2016-06-07 (10y3m) | bug | Close (unsupported version) (reported on 1.10.2): In-place MPI_Allreduce with a datatype having a large initial gap segfaulted in coll_base_allreduce. ggouaillardet fixed allreduce and reduce in 0e393195d9 (2016), first tag v3.0.0; v5.0.x coll_base_allreduce.c uses inplacebuf = inplacebuf_free - gap. No further reports. |
| #1763 | Tuned bcast data corruption | nysal | 2016-06-07 (10y3m) | bug, Target: main, help wanted | Keep (reported on master-2016 (2.x)): Tuned bcast segmented algorithms corrupt data when ranks use different count/datatype pairs with same type signature. bosilca 2020: cannot be fixed efficiently; PoC #1789 abandoned; only libnbc got a workaround (350ef67fe0). v5.0.x tuned bcast decision still picks pipeline/split-bintree for large msgs. Reproducer in issue. |
| #1666 | MPI_Accumulate Error when using datatype "MPI_SHORT_INT" | Zhiming-Wang | 2016-05-11 (10y4m) | bug | Keep (reported on master-2016 / 2.0.x): MPI_Accumulate MINLOC with MPI_SHORT_INT broken (padding/non-contig pair type). Forum agreed it must be supported; pt2pt fixed, rdma not; #2832 added an abort workaround. osc_base_obj_convert.c in v5.0.x, v6.0.x and main still has the TODO abort for these pair types. Last activity 2018. |
| #1635 | romio build failure on OpenBSD-5.7 | PHHargrove | 2016-05-05 (10y4m) | - | Close (unsupported version) (reported on 1.8, 1.10, 2.0): ROMIO failed to build on OpenBSD 5.7 because struct statfs has no f_type. Commit b159587325 (May 2016) fixed it, first released in v3.0.0. In v5.0.x, 3rd-party/romio341 ad_fstype.c only uses f_type under ROMIO_HAVE_STRUCT_STATFS_WITH_F_TYPE. |
| #1620 | OMPI-1.7 MPI_Alltoallv hang | beginZero | 2016-05-03 (10y4m) | - | Close (unsupported version) (reported on 1.7, 1.10.2): osu_alltoallv with btl tcp over 96 ranks hung or crashed with connection reset by peer. Reporter found it worked when restricted to ib0 and failed only on eth0, which points to a site network problem. Last activity 2016-06; nothing to act on for v5.0.x. |
| #1544 | Have constants available in shared library | eschnett | 2016-04-14 (10y5m) | - | Close (fixed) (reported on any (2016)): Julia MPI.jl asked for MPI constants exported as data symbols; maintainers noted handles are pointers and suggested a configure-time probe. No activity since 2016. v6.0.x changelog adds MPI-5.0 standard ABI support (libmpi_abi.so, docs/building-apps/mpi-forum-abi.rst) which standardizes constant values. |
| #1462 | Invalid memory access inside allreduce_intra_recursivedoubling | patflick | 2016-03-16 (10y6m) | - | Close (won't fix) (reported on 1.10.2): User op copied full sizeof(T) though datatype true_extent was 12 of 16, reading past reduction temp buffer. ggouaillardet and bosilca explained span sizing is correct and the op violates the MPI_Op contract; suggested padded datatype or Pack/Unpack. User accepted. Last activity 2016. |
| #1453 | suppress debug printouts in malloc.c | jiayulu | 2016-03-14 (10y6m) | - | Close (stale) (reported on master-2016): User asked how to suppress 'malloc debug: Request for 0 bytes' output. jsquyres answered it is debug-build only. rhc asked for call sites (embedded pmix_ext_server_north.c, long gone). No follow-up since 2016-03. |
| #1441 | Update usnic BTL to handle unknown senders | jsquyres | 2016-03-09 (10y6m) | enhancement | Close (stale) (reported on master-2016): Request to let usnic lookup_sender() add unknown procs so MCA_BTL_FLAGS_SINGLE_ADD_PROCS can be dropped. Only follow-up was a 2017 ask to close or defer. usnic in v5.0.x/main still sets SINGLE_ADD_PROCS (btl_usnic_module.c), but usnic has had no feature work in years. |
| #1403 | "make check" can't run any tests that use components (without installing first) | jsquyres | 2016-02-25 (10y6m) | enhancement | Close (fixed) (reported on master-2016): Request to let make check exercise component-using tests without installing first; ggouaillardet/jsquyres noted --disable-dlopen makes it work. v5.0.x changelog: default build mode changed from DSOs to static inclusion in libraries. No activity since 2016. |
| #1364 | EXC_BAD_ACCESS when calling MPI_Finalize after main() returns (OS X) | valkenburg | 2016-02-15 (10y7m) | - | Close (unsupported version) (reported on 1.10.2): MPI::Finalize from a C++ static destructor after main crashed on OS X because OPAL's registered destructor ran first (bosilca). 8cc3f288c9 dropped the opal_class_finalize destructor (v3.0.0); v5.0.x has no opal/ompi destructor and ompi/mpi/cxx is gone. Last activity 2016. |
| #1360 | shmem_align argument ordering | paboyle | 2016-02-14 (10y7m) | - | Close (won't fix) (reported on 1.10/master-2016): User hit Cray MPT shmem_align(size, align) vs OSHMEM shmem_align(align, size). bosilca pointed to OpenSHMEM 1.2 sec 8.2.1 confirming OSHMEM order; no further action. v5.0.x shmem.h.in still declares shmem_align(size_t align, size_t size), per spec. |

| #1141 | corrected/expanded message about shmem temporary directory | loveshack | 2015-11-20 (10y10m) | - | Keep (reported on master-2015): Doc fix: shmem/mmap help text says $TEMPDIR but opal uses $TMPDIR. No comments. v5.0.x and main opal/mca/shmem/mmap/help-opal-shmem-mmap.txt line 34 still say $TEMPDIR. Trivial help-text PR; the suggested orte_tmpdir_base param name no longer exists (PRRTE era) so omit or update it. |
| #1122 | /usr conflicts with RH 7/7.1 | masteele | 2015-11-10 (10y10m) | - | Close (unsupported version) (reported on 1.8.4): RPM from 1.8.4 spec conflicted with RHEL7 filesystem package over /usr/bin and /usr/lib64. ggouaillardet pointed to fix 6ab3289582 on 2015-11-12 (rpm: fix openmpi.spec not to include /usr), contained in v3.0.0+. No further activity. |
| #978 | Default binding in heterogenous bindings is weird | jsquyres | 2015-10-05 (10y11m) | bug | Close (unsupported version) (reported on 1.10.x): Default binding mishandles non-homogeneous sockets (2015 users-list report). Punted 1.10->2.x->3.x, last activity 2017-07 with no fix. Mapping/binding is now done by PRRTE in v5.0.x+, so the ORTE code is gone; any remaining issue belongs in openpmix/prrte. |
| #862 | Non-standard behavior in MPI_File_open | nasailja | 2015-09-03 (11y) | - | Close (won't fix) (reported on 1.8.8): User expected fopen(w) truncation semantics. ggouaillardet, bosilca and edgargabriel agreed MPI modes mirror POSIX open() flags and OMPI just translates them, so no truncation is correct. No activity since 2015-09. |
| #860 | OpenMPI cannot handle standard UNIX filename | nasailja | 2015-09-03 (11y) | - | Close (fixed) (reported on 1.8.8): ROMIO treats ':' as fs-type prefix; OMPIO does not. Request was to document it (PR #861 closed unmerged). 86270e7613 added the note, present in v5.0.x docs/man-openmpi/man3/MPI_File_open.3.rst. Last activity 2015. |
| #665 | TCP causes performance penalty on single-node runs | jsquyres | 2015-06-25 (11y2m) | bug | Close (unsupported version) (reported on master-2015): TCP BTL kept opal_progress event count raised even when vader was selected, slowing single-node runs (esp. macOS). bosilca PR #3738 moved increment to connection setup; merged 2017-09 as ab68aced23, first tag v3.1.0. Issue left open after merge. |
| #628 | opal_path_nfs test is undeterministic and may fail in chroot environments (such as mock) | dvandok | 2015-06-05 (11y3m) | - | Close (stale) (reported on 1.8.x/master-2015): opal_path_nfs make-check test compares mount(8) output against statfs and can fail in a chroot. jsquyres suggested exit(77) under mock and the reporter proposed HOSTNAME=mock as the signal (2016). Nobody implemented it: test/util/opal_path_nfs.c in v5.0.x/main still has no chroot/mock skip. No other reports in 10 years. |
| #475 | No protection for opening plugins from wrong OMPI version | opoplawski | 2015-03-16 (11y6m) | enhancement | Keep (reported on master-2015): Stale plugins from an older install in the same prefix get dlopened and crash. Devs agreed in 2015 to check project version, but v5.0.x and main mca_base_component_repository.c still only compare MCA 2.1 and still say 'TODO -- add checks for project version'. v5 builds static by default, but DSO builds are still exposed. |
| #442 | Fix MCA var alias problem | jsquyres | 2015-03-03 (11y6m) | bug, enhancement, feature request | Close (stale) (reported on master-2015): 2015 discussion of MCA var alias registration race; the concrete trigger was want_fork_support aliases from oob/ud and btl/openib. Last activity 2017 milestone bump. opal/mca/common/verbs and btl/openib absent in v5.0.x and main (cat-file). No owner, no follow-up. |
| #409 | OPAL MCA memory leaks | jsquyres | 2015-02-20 (11y7m) | bug | Close (unsupported version) (reported on master-2015): Valgrind showed opal signal and net_private_ipv4 MCA string storage leaked at finalize. hjelmn thought it was fixed; last ping 2017. a7b0c00ab6 (Apr 2015) removed the NULL assignments in opal_deregister_params that caused exactly this leak. |

| #321 | Fix the attribute mess | bosilca | 2014-12-20 (11y9m) | bug, documentation | Keep (low priority): George (2014) said the ompi-release#142 attribute fix was a band-aid and the real fix is a per-object flag for attribute changes during callbacks. The only reply since was a 2016 milestone move. main still uses a single global attribute_lock, and MPI_Comm_free docs still say delete_fn must not add or delete attributes on the same object. |
| #194 | Non-uniform BTL usage not working | ompiteam | 2014-10-01 (11y11m) | bug | Needs check: BTLs treated a missing peer modex key as a fatal error, which breaks mixed-BTL jobs. usnic was fixed in r31258 and tcp in r31753, and tcp on main now ignores OPAL_ERR_NOT_FOUND. But btl/ofi on main still aborts on any modex_recv failure (btl_ofi_module.c) and uct errors out. Test with an MPMD run where only one side enables ofi or uct. |
| #189 | Remove PERUSE in favour of upcoming MPI_T pvar implementation | ompiteam | 2014-10-01 (11y11m) | RFC | Needs check: 2014 proposal to remove PERUSE in favour of MPI_T. bosilca objected. jsquyres (2022) said close when #8057 (MPI_T events) merges. #8057 and #13133 were closed as superseded by #14083, which merged (783ecc7605). PERUSE is still in ompi/peruse on main, but MPI_T events currently cover only comm/win/init/errhandler events, not PML-level ones. Maintainers need to decide whether to remove PERUSE now. |
| #160 | TCP BTL does not support Linux virtual interfaces | ompiteam | 2014-10-01 (11y11m) | bug | Keep: TCP BTL gets confused by Linux virtual/alias interfaces (eth0:0) because it keys on the kernel index (kindex). bwbarrett reopened it in 2018 and explained the if_include/address-selection flaw. The same limitation is still described in a comment in mca_btl_tcp_create() in opal/mca/btl/tcp/btl_tcp_component.c on main. No fix found. |
| #139 | Use new Autoconf 2.69 Fortran m4 macros | ompiteam | 2014-10-01 (11y11m) | enhancement | Keep (low priority): Request to use the Autoconf 2.69 Fortran macros (AC_FC_MODULE_FLAG, AC_FC_IMPLICIT_NONE, etc.) once the minimum was raised. Main now requires 2.69 but still uses the custom config/ompi_fortran_find_module_include_flag.m4 and none of the macros. A configury cleanup. |
| #124 | mpi_show_handle_leaks=1 doesn't show all leaks | ompiteam | 2014-10-01 (11y11m) | bug | Keep (low priority): mpi_show_handle_leaks originally checked only comms, infos and files. Main now also checks windows (d7205f90f1, 2015). Datatypes, groups, ops, errhandlers and keyvals are still not reported. A valid enhancement. |
| #123 | Fix MPI_File auto-close on Finalize | ompiteam | 2014-10-01 (11y11m) | bug | Needs check (v5.0.x): MPI_File left open at MPI_Finalize is auto-closed after ompi_instance_count drops to 0, and ROMIO's close still calls MPI_Barrier, which trips the after-finalize check. v5.0.x still ships ROMIO 3.4.1 (removed from main by 73a55fe4fe); default ompio is unaffected. Test the 2010 reproducer on v5.0.x with --mca io romio341. |
| #46 | Add FAQ entry about firewalls | ompiteam | 2014-10-01 (11y11m) | Severity: minor, documentation | Keep: request for firewall documentation: (1) disable firewalls between nodes, (2) how to run through a firewall using port ranges. Item 1 is covered in docs/launching-apps/troubleshooting.rst. Item 2 is not: docs/ never mentions port ranges (btl_tcp_port_min etc.) or firewalls in that sense. This is a small docs task. |
| #24 | Implement MPIX_GREQUEST_START | ompiteam | 2014-10-01 (11y11m) | enhancement | Keep: request for an MPIX_Grequest_start user API with a progress callback. devreal asked to expose it in 2020 and jsquyres agreed. On main, ompi/request/grequestx.c exists behind --enable-grequest-extensions (PRs 5337/5353/6991/7546) but is internal only: there is no public MPIX API and nothing outside ompi/request uses it. |
