Hi,
I'm setting up a compute environment with a load scheduler and submit
mechanism (Sun Grid Engine) where we basically want our users to use
the submit mechanism and disallow them a direct logon to the
computational nodes of the cluster. (rsh and ssh not allowed)
For most applications this works just fine but almost every MPI
implementation requires a working, passwordless rsh / ssh logon.
This poses a bit of a problem because if I go this route, every user
will logon to a node of their choosing and start their job locally
instead of submitting it thereby clogging up resources which would
otherwise be managed by SGE.
Do you have any suggestions for this type of problem?
Thanks in advance,
Jeroen Kleijer
