Hi Trevor, what kind of jobs do you want to run on the cluster?
What I am after is: is it mainly number crunching, large parallel jobs, serial jobs, jobs which do a lot of disc IO, need much memory, visualisation..... For example, I am not the 'master' of 8 clusters and most of them have different purposes. The largest cluster has a fast InfiniBand network as people are running parallel jobs there, sometimes up to 128 cores or so. Large for that cluster but still tiny for others, I know. A different cluster has a web interface for the users, so here they can submit structures, see whether they have been calculated before, re-do it or just get the results. So here I have installed a webserver and a database (both in virtual machines, incidentally). I am using Debian as the OS here, with wheezy and jessie for the versions. I use PXE for the installation of the nodes which gives me the advantage I got a rescue OS as well in case there is a disc problem. The nodes get their IP from a DHCP server and I am running a local DNS server so the command $ ssh node1 does actually work throughout the cluster. I hope that helps you a little bit. All the best from a sunny Graz where I am on vacation!
