Go up one level in this thread
without posting all the logs (too much noise) here are the search times for 15 ply searches in this position, for 1, 2, 4 and 8 processors... log.001: time=1:33 mat=1 n=193586736 fh=92% nps=2.07M log.002: time=52.28 mat=1 n=215674371 fh=92% nps=4.13M log.003: time=29.54 mat=1 n=315208284 fh=92% nps=7.97M log.004: time=15.92 mat=1 n=328379288 fh=92% nps=14.14M speedups seem to be 1.8, 3.1 and 5.84, so my 4 cpu speedup is worse than yours, although of course one positions doesn't mean a lot... also notice my NPS is still not 8.0x faster. Here is it closer to 7.0, but I'm working on it. :)
