[Mvapich-discuss] [mvapich-discuss] MVAPICH2 2.3.5 and HDF5 1.10.7 parallel tests

[Subramoni, Hari]

Hi, All.

We had some offline discussion on this. We were able to resolve the issue. The solution will be available in the next release of MVAPICH2.

Best,
Hari.

Hi, Mark.

Sorry to hear that you're facing issues.

Can you please let us know if the is issue particular to POWER9 + Lustre + UFS combination or does it happen on x86 systems as well?

We will try out the steps you've mentioned locally and see if we are able to reproduce it.

Thx,,
Hari.

Hi there,

I'm having trouble getting HDF5's parallel tests to pass when built on top of MVAPICH2. I was wondering if anyone else is seeing this, please?

For reference (not sure it's relevant), I had similar trouble with the version of ROMIO bundled inside OpenMPI (https://urldefense.com/v3/__https://github.com/open-mpi/ompi/issues/6871__;!!KGKeukY!nWOQssfAxiSnSZJJ7bf62O6vhk438EzOmw7yXziKQ3niAaJZUYlmw-6k6nKp0Si8pwjiqKIs-3I4CJc$ )

Thanks,

Mark
