  2. Article Summary • Recent GPU history • Stream Processor ,2006, AMD acquired ATI • CUDA SDK, 2006, NVIDIA • Tesla, 2007, NVIDIA • Larrabee • Parallel CPU, i86’core processors in a line (rather than parallel and connected in a ring), sharing access to cache memory • Old hardwired instructions are gone • Like the Cell in many ways, but easier to program • Won’t be on the shelves late 2009, elephant not yet in the room • CUDA • Proprietary language for proprietary hardware • Open GPU computing • Open Computing Language (OpenCL), not ready for prime time • Brook, is obscure
