Or better still if you want to be able to pass the filename and args on
the mpirun command line use the following and then run it as
mpirun -np 64 ./input_wrapper inputs.txt my_exe
#!/bin/bash
FILE=$1
shift
"$@" < $FILE
In general though using stdin on parallel applications is rarely a good
solution.
