Meh. "Needs" is such a weird word around here, because as far as I know none of us are getting paid to do any GPGPU work. > Doesn't AMD already work on OpenCL for their cards?

OpenCL is non-trivial to support. It requires a lot of infrastructure, and a lot of per-driver code since r300 and r600 are both kind of experimental/non-working in Gallium right now. > Roland Scheidegger wrote: >> On 10.07.2009 00:06, wild-thing wrote: >>> Hello there! >>> >>> I guess this could be a feature request: (An unusual question) >>> >>> I am sure you know BOINC: http://boinc.berkeley.edu/ I am spending >>> processor time for one of the related projects as user only.

We could totally do CUDA and CTM and all kinds of GPGPU on r300-r500 cards. It would just suck a lot. Seriously, though, I expect that we'll get "free" r300 support in Gallium for a few GPGPU libs, when those libs get regular Gallium support. Just don't be surprised when it's all slow and fail. ~ C. _______________________________________________ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
