OK.
This is what I am trying to accomplish. I am trying to run a single binary on different nodes for different data sets.i.e. a single binary has to run on different data sets on different nodes....I understand that it can be done using ssh or rsh i guess....but I want to do this using MPI library.....

For example....

node1 may run --------> ./binary -in file1 -out file1-output
node2 may run --------> ./binary -in file2 -out file2-output

so on and so forth....
where in my mpi program this line(./binary -in file1 -out file1-output) is in "1-exec" and so on.....

I have tried to distribute the 'load' on each node using the rank.......but the get errors as I discussed...

Thanks

Fahad
