Therefore I would suggest to expand the benchmark for faster devices, for example nqueens with n=9, to see how much the real computation takes on the "fast" device. I noticed the issue of accurate timing for very fast results in the beginning of making the benchmark already, especially when starting with the assembly languages. The solution was to use an outer loop, that allows a much more accurate timing and making the overhead insignificant. I've used 100000 iterations for the SH-3 assembly version for example, what should be accurate enough, I guess. I've also tested larger chess boards for verifying the same speed factor. Thanks for pointing this out. Calculator Benchmark |
