Whats this Lie-nix Thing?

Hi all,

I am submitting parallel jobs like so:

mpiexec -np 12 -machinefile < nodes.inp ./myprogram

The nodes.inp file contains the list of nodes to be used. But the mpiexec thinks the ./myprogram is also a file to be read by -machinefile so mpiexec tells me that I haven't given it an executable but indeed "myprograms" is an executable. How can I tell linux to only input just one file to -machinefile (or any linux program for that matter, doesnt have to be mpiexec), obviously "<" is not working. Any suggestions could be awesome! Thanks!

mpiexec -np 12 -machinefile < nodes.inp ./myprogram

After looking at the man pages for mpiexec I do not see a reason to use <. Have you tried.
mpiexec -np 12 -machinefile nodes.inp myprogram
