Hi,

Thanks for reaching out to us.

>>> "Issue with mpirun excuting applicaciom compiled with Intel tools (Icc, mpiifort...)"

We have attached a sample mpi hello world program. Could you please try and let us know whether you are able to run sample hello world program without any issues?

Could you please provide us the sample reproducer code and the steps to reproduce the issue to investigate more on it?

>>>"Is there available any option for debugging or logging?"

Yes, you can use the options I_MPI_DEBUG=<any postive integer> and FI_LOG_LEVEL=debug while running a MPI program.

Could you please provide the complete debug log by setting I_MPI_DEBUG=10 and FI_LOG_LEVEL=debug ?

For example:

I_MPI_DEBUG=10 FI_LOG_LEVEL=debug mpirun -n <number-of-processes> -ppn <processes-per-node> -f <hostfile> ./a.out

Thanks & Regards,

Hemanth
