| Yes, the Cray X-MP.

Another problem: it is not a very common computer.  Nearly everyone who
is doing some serious benchmarking at least has access to a VAX.

If it weren't for the memory restrictions and porting problems, I'd vote
for the IBM PC with specified compilers -- common as dirt (also *runs*
as slow as dirt, but that's a different matter ;-)
