In direct answer to your question Nvidia, AMD (Formerly ATI), Intel, and others make GPGPU's they all have issues and none of them were compatible with each other in the past, but there seems to be a light stating to appear they all seem to be standardizing on support for OpenCL so at least the code is becoming portable but most of them need proprietary drivers to load code into the card. there are some notable strange exceptions Samsung is building GPGPUS for smartphones which don't need proprietary drivers. Im not completely sure what they intend to use them for but its at least one vendor and i have a feeling more will follow soon. I know there is progress on a a free AMD Radeon driver which allows you to program in openCL http://dri.freedesktop.org/wiki/GalliumCompute I haven't tried it but it shows there is potential. now someone just needs to write code to software render 3d graphic in OpenCL and maybe we will finally be able to put the proprietary driver BS to rest. > > On 03/25/2013 07:34 PM, Paul Robert Marino wrote: >> >> Um well >> Frankly the proprietary driver is never up to date with the kernel and >> it is well that's luck if it ever works with a new version of the kernel >> after you have reinstalled "recompiled the module with code you can't >> see against the new code" >> >> >> If you have a problem with the proprietary driver take it up with >> ?Nvidia.
