Thanks for the response. I did start reading those 2 sites.
I was also interested in people's opinions and experiences of any of the technologies surrounding Linux High Performance Clusters and parallel filesystems.
Is anybody out there using these technologies in production and what kinds of things are they doing and how?

clusters
clusters(4) Sun Cluster File Formats clusters(4)
NAME
clusters - cluster names database
SYNOPSIS
/etc/clusters
DESCRIPTION
The clusters file contains information regarding the known clusters in the local naming domain. For each cluster a single line should be
present with the following information:
clustername whitespace-delimited list of hosts
Expansion is recursive if a name on the right hand side is tagged with the expansion marker: ``*''.
Items are separated by any number of blanks and/or TAB characters. A `#' indicates the beginning of a comment. Characters up to the end of
the line are not interpreted by routines which search the file.
Cluster names may contain any printable character other than an upper case character, a field delimiter, NEWLINE, or comment character. The
maximum length of a cluster name is 32 characters.
This information is used by Sun Cluster system administration tools, like cconsole(1M) to specify a group of nodes to administer. The
names used in this database must be host names, as used in the hosts database.
The database is available from either NIS or NIS+ maps or a local file. Lookup order can be specified in the /etc/nsswitch.conf file. The
default order is nis files.
EXAMPLES
Example 1 A Sample /etc/clusters File
Here is a typical /etc/clusters file:

planets mercury venus
wine zinfandel merlot chardonnay riesling
Here is a typical /etc/nsswitch.conf entry:
