Re: Disrtibuted Computing Benchmarking

The biggest problem I see is finding a problem that decomposes efficiently the same in both systems. CUDA is conceptually the same as a single node of the PS3 cluster. The PS3 cluster would benefit most from a single problem that can be broken into N large subproblems which can then be broken into Y...
