malloc error when using mpi+metis

[francoisfraysse]

Dear all,

First of all, thank you to make this code available 👍

I get an error with test Euler/UniformFlow when executing it with mpi and metis partitionner, see log
log.txt

This test works with openmp or mpi + sfc partionning.

I am using gcc version 7.5.0 on ubuntu 18.04. mpich 3.2.1 and metis 5.1.0 compiled with default options except IDXTYPEWIDTH=64 and REALTYPEWIDTH=64.

Horses3D compiled with default options except COMM=PARALLEL and MODE=DEBUG

Ask me if you need any other info

Thanks again !
François

Hi @francoisfraysse,

Sorry for the long time to reply. I completely forgot about this issue. When you wrote the comment we had less experience with compiling horses with different compilers and versions of the libraries, so I didn't know what to do to try and solve the problem.
What I have seen that works is use newer versions. For example, gcc 11 or gcc 12 work well.
About metis, I use 5.1.0, just as you. I am not so sure about the MPI.
If you still have any kind of interest about this, I'll try to solve any question faster than last time :D
