I' talking about that a general multi-platform system like Mathematica can't use very special hardware in general, because the very special hardware does not exist in general. As to see from http://www.gpgpu.org/ "With desktop systems based on Tesla GPUs, Mathematica users will be able to perform complex, data-intensive computations right at their desk, negating the need to write native C programs or wait for time on a public cluster, a process which can often take days or even weeks. The CUDA accelerated version of Mathematica is expected to be available in Q1 2009." > > 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. What may be the difference between "experimenting seriously" and "support it in a product" ?? > (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). Only *one* Graphics card manufacturer support it at all. AMD/ATI will use its Stream Computing/ Brooke+ language (http://ati.amd.com/technology/streamcomputing/sdkdwnld.html) and Intels Larrabee will also have it's own languange. Moreover, it seems that BrookGPU /Brooke+ (http://www-graphics.stanford.edu/projects/brookgpu/) will become the standard and not CUDA Especial because nVidia try to sell its newes graphics cards for CUDA, while BrookGPU work well even with older ones. Also, if I understood the speakers well, one cannot go > beyond the single precision limit in general. GTX260, GTX280 can do that and this is so general as to have a GeForce Graphics card and not a Intel, ATI, S3 ...
