I suddenly became an admin of the cluster in my lab and I'm lost. I have experiences managing linux servers but not clusters. Cluster seems to be quite different.
I figured the cluster is running CentOS and ROCKS. I'm not sure what SGE and if it is used in the cluster or not.
Would you point me to an overview or documents of how cluster is configured and how to manage it? I googled but there seem to be lots of way to build a cluster and it is confusing where to start.
