at many dozens of gigaflops, how do they expect to keep the processor fed with data? What's the mem bandwidth and is it enough? How are they going to keep it fed when it's 3 or 4 times faster, then 16 times faster? Or do they expect it to work only with very restricted data sets (per-processor locally cachable), which frankly seems unhelpful for large data sets which I understand most hpc problems to be.
A crysis-worthy[*] superdupercomputer starved of bandwidth slumps into being just a pc.
[*] just thought I'd get that one out the way, clear the air a bit.
