Think carefully about what sort of problems you want to solve, e.g.
parallel computation or task farming?
If the former, then are the communications latency-bound or bandwidth-bound? Are collective communications important? Will you need full switching for remote comms, or just nearest-neighbour?
CPU-bound or memory-bound or IO-bound?

These factors are not necessarily mutually exclusive and Inevitably there are trade-offs, but one size does not fit all.

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. ATTRIBUTES
