Sun Ras.

One has to think really hard to justify why a SMP machine
with 64 cpu's would be preferable over 64 PC's in a Beowulf
cluster. Like you say, RAS is naturally easier with a
distributed program which utilises the software level to
manage the hardware. Where large CPU SMP's come in is where
large traffic low latency becomes an issue, for example
transaction processing. The extra layer of software (eg
Beowulf or even PVM) and network speed increases the
latency significantly. Of course, price/performance is the
key metric and so long as the machines are economical, they
will find a market.
