It's a known race condition problem that has been fixed for the 1.3.1 release - hope to have that out in the near future.

Sorry

I have searched for solutions to this problem, but have not been successful. The following command works okay when using Open MPI 1.2.8:
 
      shell$ mpirun --hostfile procs -np 5 my_app < my_input
 
However, the above command produces the following error message when using Open MPI 1.3:
 
      forrtl: severe (24): end-of-file during read, unit -4, file stdin
 
Note that all the processes have access to the "my_input" file. Also, I have tried different process ranks for the "--stdin" flag to no avail.
 
Anyone have any ideas or can point me to a solution?
 
Thanks.
