Yes and no :)
You first need to identify what you want/need:
* what is the (typical) problem you want to solve?
* what software do you need for that, do you need a batch scheduler or do you
have very few users which work at the same place and share the cluster without
* think about the OS (Debian is a good choice here ;))
* Think about the compute hardware, you probably need a login node, execute
nodes and a file server, do you need many local cores or are the problems too
large to fit into a few nodes? Then you need to look into networking
(Infiniband or high performance Ethernet), is the software susceptible to
latency and/or bandwidth available......
You see there are MANY questions to look at first, before you even want to
start installing the machines :)
Try describing a "typical" problem, the sizes involved, that may help a lot.
