Intel Oneapi mpirun issue

[jainiltrivedi2022]

Hello there.

I am using intel oneapi MPI Library to work on one model.

(mpirun version = Intel(R) MPI Library for Linux* OS, Version 2021.2 Build 20210302)

My issue is that when we try to compile any program with mpif90 or any other compiler, it is able to generate the executable file and when we try to run that executable file without using MPI it is able to produce the desired output.

However, when we try to run that executable file using 'mpirun' command with 4 or 8 number of processes it is not producing output as well as not giving any kind of error and program is stuck. Following command I tried to execute after compiling file:

(Command: mpirun -n 4 ./filename)

One noticeable thing is when we run above command it is invoking 'hydra_pmi_proxy'.

Hope to receive valuable help.

Hi,

Thanks for posting in Intel Communities.

Could you please provide us with the OS and Hardware details of the machine you are using?

Could you let us know if you are able to run the sample hello world code(attached the code)? If you are able to run the sample code without any issues then please provide us with the sample reproducer you are trying to execute.

Please find the below commands for compiling and running MPI code:

Compilation: mpiifort test_mpifortran.f90 -o test
Running:  mpirun -n 3 ./test

And also, could you please provide us with the complete error log(screenshot) you are facing at the time of execution?

Thanks & Regards,

Varsha

Thank you for considering my query.

Yes, I was trying to execute the same hello world code for testing. Also, I had applied the same set of commands that you suggested.

OS Specifications:

$ uname -a

Linux wks08 4.18.0-383.el8.x86_64 #1 SMP Wed Apr 20 15:38:08 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Hardware Specifications:

$ lscpu

PFA.

Executed following commands:

$ which mpiifort
/opt/intel/oneapi/mpi/2021.2.0/bin/mpiifort

$ mpiifort test.f -o prog

$ mpirun -n 3 ./prog

It showed no output. However, I had taken the snapshot of 'top' command.
