I wonder how the latest >crays stack up against those Compaq beasties. With the right kind of programming, the T932 will simply blow the doors (and the paint) off of any of those machines. Remember the simple math: each cpu can read 32 bytes per clock cycle, and write 16 bytes per clock cycle. That is 48 bytes, times 32 cpus, at a clock rate of 500mhz. I think that _any_ machine will choke when presented with that kind of data throughput requirement. :)
