One comment on SPEC. It is a workstation benchmark as far as I can see. For supercomputers, even Perfect is not. (Some of the codes in there may be). What is the point of running a 12 second, 16 MByte problem on a supercomputer? And Nothing, just about, scales up linearly! So it is useless to run a small version of a big problem. And, it is not always the case that you increase the dimensions and run the program again and you have a supercomputer application! At some point you need new code, new algorithm, new science. I think in some areas applications are not being developed as fast as hardware is! Can it be that too many scientists are busy making back-ups of their pc's?! Shahin. disclaimer,etc.
