Re: [OMPI users] hwloc error

[Brice Goglin via users]

Hello Dwaipayan

You seem to be running a very old hwloc (maybe embedded inside an old Open MPI release?). Can you install a more recent hwloc from https://www.open-mpi.org/projects/hwloc/, build it, and run its "lstopo" to check whether the error remains?

If so, could you open an issue on the hwloc github at https://github.com/open-mpi/hwloc/issues/new?

Thanks

Brice

Your error looks strange. We've seen issue with such "intersection" errors in the past because the BIOS or ACPI was reporting invalid cache or NUMA affinity with respect to CPU packages. But intersecting packages is really unexpected. Among what's requested in the issue template, the important information that we'll need is the tarball generated by hwloc-gather-topology, it will allow us to check that Linux is indeed reporting invalid socket information. By the way, this mailing list is for Open MPI, the hwloc mailing list is hwloc-us...@lists.open-mpi.org. Please use that list if you want to discuss by email instead of in a github issue.

Recently, I have been facing issues while using the CFD software package ANSYS Fluent in my local machine which have two Xeon processors with 12 cores each. Whenever I am trying to run a simulation in parallel, it gives me this warning And then when I run the simulation it abruptly stops giving me a segmentation fault
