Note that Andrej Sali mentioned they were going to use Clustor, which I
know well as it's the commercial version of the Nimrod system developed
by my colleague David Abramson.

Nimrod/Clustor provide an overall execution  management regime across
multiple systems. It's particularly suited for problems that can be
partitioned, such as atmospheric modelling, etc. etc.

We have built a cluster of rack-mounted 330MHz Pentiums specifically for
running Clustor-based applications. We can use either Linux (RH at
present) or NT or a mixture of the two.
