[Harms, Kevin]

Pramod,

  are there ayn environment variables that can be set to print out what the error code is? Did you build libdarshan using the HP MPI?

Subject: [Darshan-users] About HPE MPI (MPT) support in Darshan (MPT ERROR: PMI2_Init)

Dear All,

I was trying to use Darshan (3.1.6) with HPE MPI (MPT)<https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00037728en_us&docLocale=en_US> on our system and seeing below error:

LD_PRELOAD=/gpfs/some_path/lib/libdarshan.so  srun -n 1 /gpfs/some_another_path/bin/ior -a MPIIO -b 1G -t 4M  -c  -i 3
MPT ERROR: PMI2_Init

With other MPI (e.g. intel-mpi), everything is working fine.

Do you have any suggestions / workaround? Please let me know and I could help to debug/test the issue.

Regards,
Pramod
