From: Amir on 26 Nov 2008 05:11 We are thinking of making some equipment purchases for CUDA use. Can someone detail what the CUDA support is in this release of Mathematica if any? We haven't received a copy of 7.0 yet and the new documentation doesn't mention CUDA or how it's integrated, but it has appeared in Nvidia marketing blurbs. For example, will it be use-able with a only newer Nvidia cards? How does it get around the use of single precision in current cards? Thanks, Amir.
From: Jens-Peer Kuska on 26 Nov 2008 07:22 Hi, a) Mathemnatica run on Solaris and system with ATI/AMD cards so there can no general support fo CUDA b) it is simple to make a MathLink program that use CUDA and *this* is the support that exist since version 2.0 Regards Jens Amir wrote: > We are thinking of making some equipment purchases for CUDA use.

Dear Amir, CUDA supported products are at: http://www.nvidia.com/object/cuda_learn_products.html I can't wait to get my hands on Mathematica 7 so that I can try and run some parallel calculations on the GPU. >From what I've read up until now it supposed to run the calculations from Mathematica directly without the need for compiling the C code. As for the double precision, the new Nvidia boards should have it. I you get to try Mathematica 7 with CUDA, let me know your results. Antonio
From: Amir on 27 Nov 2008 05:29 Our sales rep indicated that Mathematica would have support for CUDA. I think I misunderstood her in what form the support would appear. I assumed it meant integrated into new parallel commands. Thanks for posting your CUDA template mathlink scripts. I have used them.

Hello, I do not really understand what you are talking about here, Jens, and on what basis. But I know from a very good talk (on the Mathematica users conference and not under NDA) by one person of Wolfram Research and another one of Nvidia, that they are experimenting seriously with CUDA. (Alltogether it seems not to be that simple, it was said that one requires good support by the graphics card manufacturer in order to get it going). Also, if I understood the speakers well, one cannot go beyond the single precision limit in general. So, I understand that only specific numerical code parts can be executed on the graphics card (?). If such support makes it into a future version of Mathematica, I, of course, don't know.
