Could you please include (a) what version of OMPI you are talking about, and
(b) the binding patterns you observed from both srun and mpirun?

Hi,
I wonder if mpirun can follow the cpu binding settings from slurm, when running
under the slurm environment.
Currently, in my tests, when I run
srun bash -c "cat /proc/self/status|grep Cpus_allowed_list"
I saw the correct binding set by salloc. When running
mpirun bash -c "cat /proc/self/status|grep Cpus_allowed_list"
The bindings are not correct.
Thanks,
Chang
