But it seems that too much RAM is being ussed up. All I have done was boot
up the slave nodes, and have not run anything on them. Or is this normal?

Also, another question is about mpi. I have ran a simple test code on
the cluster, and some processes seem to run on the master node. What do I
have to do to prevent this from happening? So that the processes only run on
the slave nodes.
