I'm trying to install MPICH on a small cluster of powermac G4's
running opensuse 10.1 . The machines are in a campus network
environment with no cluster-specific fileserver, central LDAP host
etc. While I have been able to compile and install MPICH, I can't
get the ring up and running (mpdboot fails).
What sort of network connection do I between the cluster of
machines? I can ssh to and fro within the cluster (with a
password). Do I need to set up a fileserver to run MPICH in a
satisfying way?
What is the proper way to set up ssh so that once I've connected to
one machine within the cluster I never have to enter a password again
to move within the cluster? Is this what is necessary to get MPICH
to run?
regards,
Nathan Moore
