Add cgroup_cli.sh, a simple CLI tool wrapping systemd-run for starting, stopping, and monitoring synthetic workloads. This tool is useful for building microbenchmark experiments that stress particular scheduler functionality. See more in README.md. 2 example experiments are included. One illustrates launching 10 cpu hog threads across 4 cgroups each with 10 CPUs. Another demonstrates launching 2 cpu hogs across 2 CPUs which are chosen to be on different LLC slices on a given architecture.

Looks good in general, but can we have a single script that takes different arguments for different combinations? |

Sorry @kkdwivedi, just back from PTO. Combining synthetic_workloads/expts/* into one script? Sure thing! |
