Description

That's the second time I see this pop up (first was month(s) ago). Does not seem to be predictable.

It means that the supportLevel() is SupportLevel::LogicalProcessorCount.

Stop using hwloc on old ARM slave

We're not sure what the problem is, but it will never be
a priority to fix it.

Fixes #2284

History

#1 Updated by Szilárd Páll over 3 years ago

I think we should disable it, it really isn't relevant on this old 32-bit ARM chip. Alternatively, we could install a newer hwloc, but I'm not sure it's worth the effort.

#2 Updated by Erik Lindahl about 3 years ago

  • Tracker changed from Bug to Task
  • Priority changed from Normal to Low
  • Affected version deleted (git master)

This seems to be a bug in hwloc rather than Gromacs, so changing it to a task.

#3 Updated by Mark Abraham over 2 years ago

  • Target version set to 2019

Still happening:

Cannot determine basic hardware topology from hwloc. GROMACS will still

work, but it might affect your performance for large nodes.
Please mail gmx-developers@gromacs.org so we can try to fix it.

We can just disable hwloc in the matrix
