This is something most of the high-end investment banking houses here in NYC and also in the UK are seriously looking at. We currently use symphony based grid orchestration for lot of our compute power needs for various risk calculations (monte-carlo simulations, prepayment modeling and fixed income risk calculations). But now several teams are trying to evaluate moving to GPU based computing. My initial reactions to this was that GPU based computing is good if you are doing a "pure-maathematical-grind" type of calculations rather than something that requires an "if-else" type structured logic. Well that does not come to me as a surprise as GPUs were primarily built for that kind of stuff - image rendering or graphics type programming, where matrix algebra is the cornerstone for all computations. What we were a little hesitant as part of our evaluation and future possible adoption was that someone using CUDA is sort of married to the architecture and its hard to unplug out of it. Most of the code logic in CUDA world is very intrusive and not platform agnostic. Might not be a big issue but this is something software engineers are usually cautious about. (P.S: we were looking at the NVIDIA based products). But on the flip side there is huge-huge cost savings in hardware needs and data center needs. We were amazed by the amount of reduction we would have in h/w if we ever redid all of our code using the CUDA based API. While this space is sure to evolve in the very near future in terms of compute power needs, I also have a strong suspicion that the likes of Intel/AMD will try to put something in place in their architectures to prevent or limit folks from leveraging the massive GPU power or at least make sure that they are somehow the part of the equation. At the end of the day the "instruction-set" or the brain power still is with the main CPU and they (Intel/AMD) could tweak things around... Cheers!! Uttam,

What a site. You have a real knack for making a blog readable and easy on the eyes. Some sites look like train wrecks, but not yours - it's a pleasure to read. I find wireless phone technology very interesting. I have learned a lot in implementing a small VoIP network at home, and am thinking of starting VoIP business in my area. There are a number of small businesses in my region that would benefit from it greatly. Wow! What a site. You have a real knack for making a blog readable and easy on the eyes.
