Hi John,
I just found no STREAM benchmark results were posted for the Fujitsu VPP5000 machine, right ?. As long as it is truely a supercomputer (peak > 1TFlops for 128 processors) with a pure distributed memory architecture I thought it could be interesting to measure it. So here are the results. I am not sure why Fujitsu Japan never released the numbers, but anyway anyone having access to such monster can easily run the test, so I did. Results are quite good I guess, feel free to publish them - well, hummm, seems to be one of the best single processor result so far...!
Regards,
Pierre.
