mpi failed using Intel sample code

ramy_a_ — Mon, 11 Apr 2016 16:44:45 GMT

Hi,

I have installed intel parallel studio xe cluster edition 2016 on HPC environment.

All compilers are working fine.

when I tried to execute the following commands:

#mpirun hostname

#mpirun --machinfile hosts hostname

It executed successfully returning all nodes' hostname

And I compiled the following sample <Intel_DIR>/compilers_and_libraries/linux/samples/en/mpi/test.c

using the following:

#mpiicc test.c

and execute the following command:

#mpirun a.out

#mpirun --machinfile hosts a.out

but I got the following error:

HYDU_create_process (../../utils/launch/launch.c:622): execvp error on file a.out (No such file or directory)

I wonder what might cause this error

Appreciate your help.

Thanks

Hi,

Could you please make sure that a.out is available on all the nodes from the hostfile? Also try to run the following variations of your initial command:

mpirun --machinfile hosts ./a.out

mpirun --machinfile hosts <full_path>/a.out

Thanks Artem.
