Are you able to update the MPICH version? MPICH 3.2.1 was released in 2017 and is no longer actively supported/maintained.

Niyaz, I don't know what prevents your from using shared memory. But in the meantime if you want to turn off shared memory, you could try configure mpich with --without-ch4-shmmods. -- Hui ________________________________ From: Niyaz Murshed <Niyaz.Murshed(a)arm.com> Sent: Friday, July 5, 2024 9:14 AM To: discuss(a)mpich.org <discuss(a)mpich.org>; Zhou, Hui <zhouh(a)anl.gov>; Jenke, Joachim <jenke(a)itc.rwth-aachen.de> Cc: nd <nd(a)arm.com> Subject: Re: Custom rank for processes Hi Hui, Any suggestion on this ?

The -hosts options is convenient if you have somewhat uniform assignment. If you want arbitrary assignment, just use -rankmap option. -- Hui ________________________________ From: Niyaz Murshed <Niyaz.Murshed(a)arm.com> Sent: Monday, July 1, 2024 4:30 PM To: Zhou, Hui <zhouh(a)anl.gov>; discuss(a)mpich.org <discuss(a)mpich.org>; Jenke, Joachim <jenke(a)itc.rwth-aachen.de> Cc: nd <nd(a)arm.com> Subject: Re: Custom rank for processes Sorry to bother you again with silly questions.

"-rankmap (vector,1,1,0,0,0)" is a list of 5 node ids, one for each rank. So rank 0 gets node 1, rank 1 gets node 1, rank 2 gets node 0, and so on. The -hosts options is convenient if you have somewhat uniform assignment. If you want arbitrary assignment, just use -rankmap option. -- Hui ________________________________ From: Niyaz Murshed <Niyaz.Murshed(a)arm.com> Sent: Monday, July 1, 2024 4:30 PM To: Zhou, Hui <zhouh(a)anl.gov>; discuss(a)mpich.org <discuss(a)mpich.org>; Jenke, Joachim <jenke(a)itc.rwth-aachen.de> Cc: nd <nd(a)arm.com> Subject: Re: Custom rank for processes Sorry to bother you again with silly questions.

I believe there has been an error in packaging, possibly resulting from a change in configure options, that has rendered the MPICH library incompatible with Hydra's mpiexec. ☹ I have no good solution besides building your own MPICH from source. I will reach out to the Ubuntu maintainer about the issue. Thanks for reporting.

Re: [mpich-discuss] All processes only find themselfs

Hm, there is a PMIx dependency that is presumably coming from the MPICH library. MPICH's mpiexec is not compatible with an external PMIx, so I suspect that is the issue. Can you try setting MPIR_CVAR_PMI_VERSION=1 and see if that works?

Can you confirm which MPI library you binary is linked with using ldd? Adding -v to the mpirun command should also provide some clues in the PMI client/server traffic.
