High Performance Computing
I am interested in setting up some High Performance Computing clusters and would like to get people's views and experiences on this.
I have 2 requirements:
1. Compute clusters to do fast cpu intensive computations
2. Storage clusters of parallel and extendable filesystems spread across many nodes
Both of these should run across multiple commodity hardware nodes and ideally be Linux/Unix based and open source.
Any feedback welcome.

chosts
chosts(1M) System Administration Commands chosts(1M)
NAME
chosts - expand cluster names into host names
SYNOPSIS
$CLUSTER_HOME/bin/chosts name [name...]
DESCRIPTION
The chosts utility expands the arguments into a list of host names.
OPERANDS
The following operands are supported:
name The parameter name can be a hostname or a cluster name. If name is a hostname, it is expanded to be a hostname. If name
is a cluster name, that is, an entry exists in the /etc/clusters database (or a NIS or NIS+ map), it is expanded into
the list of hosts that make up that cluster, as specified in the database. The list is typically used by programs that
wish to operate on a list of hosts.
If an entry for clusters has been made in the /etc/nisswitch.conf file, then the order of lookups is controlled by that
entry. If there is no such file or no such entry, then the nameservice look up order is implicitly nis files.
