It is a bit weird if you claim to be NDA bound, whereas the news has it in big capitals what the new IBM CELL can deliver.
I thought he was referring to double-precision on Nvidia gpus, which have indeed not been shipped publicly (afaik).
So a very reasonable question to ask is what the latency is from the stream processors to the device RAM.
sure, they're GPUs, not general-purpose coprocessors. but both AMD and Intel are making noises about changing this. AMD seems to be moving GPU units on-chip, where they would presumably share L3, cache coherency, etc. Intel's Larrabee approach seems to be to add wider vector units to normal x86 cores (and more of them). I personally think the latter is much more promising from an HPC perspective. but then again, both AMD
and Nvidia have major cred on the line - they have to deliver competitive levels of the traditional GPU programming model. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
