Oneapi compability issue

[hikaruseven]

Dear Developer and Users,
I used the intel compiler for the mpi implementation in the SERPENT2 parallel
calculation. However, per 2021 the whole intel compiler is integrated into
one single software, which is called oneapi. Since then, whenever i tried to
do the serpent2 calculation with multiple nodes in my cluster the calculation
will be stopped and error at sharing input to the mpi task. While it work properly
with one node.

Have you guys ever experience this issue and would possibly offer some
solution?
Thank you So much for the help

Hi,

Thanks for reaching out to us.

Could you please share with us the OS details along with the result of the below command:

mpirun --version

Can you specify whether the application consists of C or Fortran-specific MPI code?

Could you please try using "verbs" as libfabric provider as mentioned below before running the serpent 2 calculation & share with us the complete log by keeping I_MPI_DEBUG=10?

export I_MPI_OFI_PROVIDER=verbs

Thanks & Regards,

Santosh
