[mpich-discuss] Parallel jobs

Hi Talla

It sounds like all processes are trying to read from stdin, right?
Stdin/stdout are not guaranteed to be available to all processes.

Have you tried to add these flags in your mpiexec/mpirun
command line:  "-s all" ?
Check the meaning with "man mpiexec".

My two cents,
Gus Correa
