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 the other processes.
The option "-stdin rank" doesn't help since i need all processes read the inputs.txt file.
I'v tested with openmpi 1.3 and 1.2 whitout success.
Thanks in advance for you help.
