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

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

tdin problem
As a slight modification, you can write a wrapper script
#!/bin/sh
my_exe < inputs.txt
and pass it to mpirun.
