As a side-question, if the PIO build assumes it's using OpenMPI 3. rather than 4., would it be compiling differently?
On the NERSC/Perlmutter cluster (Cray+SLES) I'm seeing about 50% failures in the make check
.
I suggest that you try using the cmake build. I have confirmed that this works on the ncar gust system with nvhpc/23.1 - on the perlmutter system I don't see nvhpc/23.1 in the list of available compilers. There is nothing in PIO that handles openMPI 3. different than 4..
I also ran the parallelio tests on gust and all 108 tests pass.
I cannot find openmpi on perlmutter - I'm not sure how I can help further.
Do you use spack on perlmutter? If so parallelio is a spack package - are you using that?
I'm building PIO 2.5.10 using OpenMPI 4.1.5 built with the NVHPC 23.1 compiler. During the configuration phase, I see these messages:
If I run the command
it gives this output
It looks to me like this had been parsed incorrectly, to get
23.1 -> 3.1
