[OMPI users] OpenMPI Segfault when psm is enabled?

[Saliya Ekanayake]

Hi,

I've been trying to resolve a segfault that kept occurring with OpenMPI
Java binding. I found this thread in OpenMPI mailing list (
https://www.mail-archive.com/***@lists.open-mpi.org/msg27524.html) that
suggested to disable psm as a solution.

It worked, but I would like to know what this module is and is there a
disadvantage in terms of performance by disabling it?

Thank you,
Saliya

PSM is the infinipath driver, so unless you have some infinipath hardware,
you can safely disable it

Cheers,

Gilles
