Okay, your tests confirmed my suspicions. Slurm isn't doing any binding at all
- that's why your srun of get-allowed-cpu-ompi showed no bindings. I don't see
anything in your cmds that would tell slurm to bind us to anything. All your
salloc did was tell slurm what to allocate - that doesn't imp

1. please do send the output from ompi_info
You can find them attached to this email.

Any help will be greatly appreciated.
Thanks!
