Title: GPU low-level programming? Post by: Proofer on November 29, 2011, 02:52:51 AM Can AMD/ATI GPUs be programmed in -- not sure this CPU terminology is appropriate -- assembly language? Is there an instruction set specification for the various cards available somewhere? --Haven't found such things (yet) on an AMD site.

I also looked at the source code for cgminer and its assembly language module.Title: Re: GPU low-level programming?
