OK, so maybe not heroic. But my attempts at getting MPI running are much like an uphill battle.

I managed only partly, so far, so here are some notes:

  • I used passwordless-hostbased-ssh logins between the nodes
  • I used Torque as the batch system
  • I used the RHEL4 provided openmpi (that does not include the tm module, hence the ssh stuff)
  • It worked with torque
  • It does not yet work with CREAM, als all the processes are run on the same node.
