This is what CentOS installed. $ yum list installed hwloc\* Loaded plugins: langpacks Installed Packages hwloc.x86_64 1.11.8-4.el7 @os hwloc-devel.x86_64 1.11.8-4.el7 @os hwloc-libs.x86_64 1.11.8-4.el7 @os
I will ask my coworker to install a test version. What can I do by way of flags or environment variables to get the best output to report? I believe that `srun` is preferred as the process starter on Slurm clusters, but I think `mpirun`/`orterun` has better debugging capabilities?
