I've heard of people making clusters out of Alphas running Linux
before - can't remember where, but I did see someone had done it.
Here at Sanger, we used to have a 400 node cluster of AlphaServer
DS10Ls running Tru64. We have long since got rid of them and
switched to Linux on X86 hardware, the main reason being cost. It
really isn't cost-effective to carry on maintaining old
AlphaServers. HP start charging a *lot* of money for maintenance
after a while (more, in fact, than it would have cost to replace the
machines with more powerful X86 boxes).
So I'd be tempted to say don't bother with an Alphaserver cluster at
all any more, but if you are going to have one, it can be made to
work with either OS.
