I'm an undergrad and have been working on getting a simple 5 node
cluster (of Pentiums) up and running for some simple parallel computing
experiments. I've gotten Scyld ("Label Side Up Edition" ver 27bz-8) up
and running fine. However the problem I'm having is that I can't get
mpirun to work correctly. Using linpack and the mpich example programs

-I can use the BProc system calls to pass messages and compute on the
child nodes, however I want to write somewhat cross-platform code.
I feel like I need to install some library or rpm that the default
install fails to. However I've looked high and low and none of the
install tutorials mention any extra steps beyond the default install.
Thanks for the help,
