OpenCL is indeed very interesting, as a cross-platform version of CUDA. Some programs can get absurdly faster with relatively little porting effort. I recently handed an image registration program back to its authors with a 10x speed up - and was apologising for not making it faster (another 3x should be available). The toolchain isn't quite mature yet, unfortunately, and Apple machines can't have decent GPUs in them yet (that said, I have a machine with decent GPUs, and I've just wasted a day trying to upgrade to Fedora 10....).

CUDA is hot for quants now too...

Not sure what this means for me, as the Chicago financial scene is still pretty cratered, but I do think about the implications...

I heard that with many Chrysler stores shutting down and worries that "Obama Motors UTLC" {unlimited taxpayer liability concept} lots of current Challengers are going into "museum" garages of people that fear only Al Gore approved vehicle will come out of UAW staffed plants...


Back on topic -- does anyone hear anything about Apple are REAL HPC these days? I mean I understand that is such a sliver of a niche that it does not matter to the dollar & cents directly, but it strikes me that there is TREMENDOUS MIND SHARE to be held / gained from stressing the fact that even the MBPs have uniquely powerful graphics hardware that COULD also be used for a range of numerically intensive computations...

Anyone ???

I know people who like giving presentations on their MBPs, with live calculations provided by the onboard GPU. It gets people's attention. That said, the HPC community is not that impressed by NVIDIA's current products. There's no ECC RAM and the fault reporting hardware isn't up to the standards of Cray and IBM.

stan and YDD -- could you email me your experiences and references on that? that'd be an interesting story to pitch.

ddt:

I wish I was having some real experiences. Although I am currently completely and gainfully employed in a financial services firm, I am not working in the HPC part of things right now as the firm I work for can no longer afford their own inhouse staff for that area...

My buddies that are at firms that DO have some budget for this are HIGHLY CONSTRAINED by their firms' general risk intolerance.
