Three runs. First with one cpu, second with two threads, hyper-threading turned off. Final with hyperthreading on and using four threads: log.001: time=1:25 cpu=100% mat=0 n=85541803 fh=91% nps=1002k log.001: time=55.76 cpu=100% mat=0 n=62194368 fh=95% nps=1115k log.001: time=1:40 cpu=100% mat=-1 n=89351765 fh=94% nps=892k log.001: time=1:17 cpu=100% mat=0 n=82359320 fh=92% nps=1056k total time used = 317.76s log.002: time=58.39 cpu=198% mat=0 n=93417000 fh=91% nps=1599k log.002: time=32.12 cpu=199% mat=0 n=57789717 fh=95% nps=1799k log.002: time=1:01 cpu=195% mat=-1 n=88101174 fh=94% nps=1431k log.002: time=55.31 cpu=197% mat=0 n=92187038 fh=92% nps=1666k total time used = 206.82 1.54X SMP speedup (two threads/processors) log.003: time=53.90 cpu=397% mat=0 n=107889313 fh=91% nps=2001k log.003: time=25.70 cpu=395% mat=0 n=57514689 fh=95% nps=2237k log.003: time=1:03 cpu=396% mat=-1 n=113942925 fh=93% nps=1800k log.003: time=41.66 cpu=396% mat=0 n=86861862 fh=92% nps=2085k total time used = 184.26 1.73X SMP speedup (four threads, SMP on, two processors) I'm sure that if I run them multiple times, there will be some variability of sorts. However, none seem to be "badly behaved" positions so I don't think the variability will be wild. any more tests I should run??? Not that four positions is particularly interesting in terms of a test of anything. Or, as I expect, I'm sure something is wrong with these results too... Not particularly bad or good performance in my opinion, but that is just one small test set that is as meaningless as any other small test set...
