OpenMPI 4.1.5

[bdevcich]

Any plans to update to the latest stable version of OpenMPI?

[alculquicondor]

It should just work. Feel free to send a PR.

IIRC, we don't specify the OpenMPI version. So just rebuilding the image might be enough.

&& apt install -y --no-install-recommends openmpi-bin \

It appears that 4.1.0 is the latest that is going to be provided with bullseye: https://packages.debian.org/bullseye/openmpi-bin. I didn't see any updated packages in the updates.

It looks like bookworm has 4.1.4: https://packages.debian.org/bookworm/openmpi-bin

Any concerns with building openmpi from source?

I see.

I want to avoid building the OpenMPI to avoid increasing maintenance costs.

Actually, we already have a PR to update the Debian version, although there are unresolved issues: #573

Can you try to update the Debian version instead of building OpenMPI?

WDYT? @alculquicondor @terrytangyuan

[alculquicondor]

Yes, prefer to update the debian version.

[terrytangyuan]

Agreed. We should not build it from source

[bdevcich]

Thanks.

Makes sense. It adds some complexity. I think 4.1.4 (that comes with bookworm) will be fine as it contains the fix that we're interested in.

So the path forward is to get traction on #573 ?

I think you can open the new PR :)

[alculquicondor]

In any case, you should be able to run any version of OpenMPI with the operator. You can build your containers against bookworm (or any other distro).

@bdevcich @tenzen-y is there a reason why we do not make the install from source?

• OMPI

As I mentioned the above (#588 (comment)), we should avoid increasing maintenance costs.
