[Nottingham] Linux PC super-cluster possible?

[Martin]

Folks,

Is it possible to...

Have a number of PCs, interconnected by LAN, appear as a single
multi-cpu system?

That is, you write a program with multiple parallel threads, and you can
then run it unchanged on the multi-PC cluster as though it was on a
multi-CPU single PC?

Another requirement is that as far as the application software and LAN
activity is concerned, contact with anything else on the network that is
not part of the cluster must appear as a single computer.

Possible?
Hackable?
Ideas?

Cheers,
Martin
