Making lam work across multiple machines

To make lam work across multiple machine take the following steps:

  • Create a bhost file
      bunter.nist.gov cpu=4
      hobson.nist.gov cpu=4
      alice.nist.gov cpu=4
    
  • $ export LAMRSH=ssh
  • $ lamboot -ssi boot_rsh_ignore_stderr 1 bhost
  • $ mpirun -np 12 python script.py

This should then work transparently across the three machines. The stdout streams from the other machines didn't appear on the screen, but they were certainly running in parallel.
