Ok. OpenPMIx is the "bottom" of the stack of Open MPI --> PRRTE --> OpenPMIx, so fixing the 32 bit issues there first is what makes sense -- see https://docs.open-mpi.org/en/v5.0.x/installing-open-mpi/required-support-libraries.html#library-dependencies.
We have been trying to get Open MPI v5.0.0 out for quite a while, and seem to actually be getting closer to getting over the finish line. So getting these fixes in sooner rather than later would be better. ________________________________ From: Yatindra Vaishnav <yatindr...@hotmail.com> Sent: Monday, February 6, 2023 2:56 PM To: Jeff Squyres (jsquyres) <jsquy...@cisco.com>; devel@lists.open-mpi.org <devel@lists.open-mpi.org> Subject: RE: [OMPI devel] 32 bit support needs a maintainer Yes Jeff, I can give roughly 5-8 hours a week.

What kind of timeframe do you have to work on this? Will you be able to look into the OpenPMIx 32-bit bugs in the immediate future, and then start testing with PRRTE and Open MPI?

And yes I responded to the same mail. I registered myself for OpenMPI development community. And I'm aware about the responsibilities. And I can setup a 32-bit VMs to do bug fixes and testing. I already have a server machine which I can help with.

Just curious: are you replying in response to the discussion that just came up a few days ago on https://github.com/open-mpi/ompi/pull/11282, where we set the upcoming Open MPI v5.0's configure script to abort in 32-bit environments? I.e., are you part of the Debian community? Regardless, there are several aspects of 32 bit support that are needed: * Bug fixes in OpenPMIx * Potential bug fixes in PRRTE * Potential bug Open MPI * Testing of all 3 of the above Specifically: we know that there are 32-bit bugs in OpenPMIx that need to be resolved. As such, we stopped testing 32 bit in all 3 projects quite a while ago. Hence, even when 32-bit support is re-enabled in OpenPMIx, other 32-bit bugs may surface in PRRTE and Open MPI that require fixing. There will also need to be continual testing of all 3 of these in 32-bit environments. This likely doesn't mean writing new tests, but rather running at least some subset of our existing tests in 32 bit environments to ensure that everything works properly. Is this something that you would be able to provide?
