Hello Jeff and Kiril,
Thank you for your responses. Based on the information you both provided, I
was able to get buildrpm to make the OMPI RPM the way I wanted. I ended up
having to define _prefix , _mandir , and _infodir .
Additionally, I found I had to use --define "shell_scripts_basename
FWIW: an upcoming version will have the ability for you to specify all
ranks to receive stdin...but that's a little ways off.
For now, only rank=0 does.

In general though using stdin on parallel applications is rarely a good

#!/bin/sh
my_exe < inputs.txt
and pass it to mpirun.

Ok thanks!
That's a solution but i was wondering if there could exist a more elegant one ?
means without any modification at the source level

Why not modify your program to read inputs.txt instead of stdin?

Dear all,
I'm trying to lunch an MPI program using the command
mpirun -np 64 my_exe < inputs.txt
inputs.txt actually contains the entries that are read by all processes
however it seems that openmpi redirect the stdin only to the processes with
rank 0. with leads to a segmentation fault on th
