I ran two speed tests: 1.7 Ghz WIN2K default hash and no crafty.rc ============================================== your version on my machine: 1st test: bench Total nodes: 89942714 Raw nodes per second: 595647 Total elapsed time: 151 SMP time-to-ply measurement: 4.238411 2nd test: wac 300 with sd=8, st=9999 command test d:\wac.epd 2 total positions searched.......... 300 number right...................... 290 number wrong...................... 10 percentage right.................. 96 percentage wrong.................. 3 total nodes searched.............. 49316196 average search depth.............. 4.5 nodes per second.................. 636584 my version version on my machine: =================================================================== same tests for with my version for my machine 1st test bench: Total nodes: 89942714 Raw nodes per second: 637891 Total elapsed time: 141 SMP time-to-ply measurement: 4.539007 2nd test: wac 300 with sd=8, st=9999 command test d:\wac.epd 2 total positions searched.......... 300 number right...................... 290 number wrong...................... 10 percentage right.................. 96 percentage wrong.................. 3 total nodes searched.............. 49316196 average search depth.............. 4.5 nodes per second.................. 685899 =================================================== so for my machine, my version is about 6-8% faster -- and it may be slower on your machine -- all falls under the category - YMMV - your mileage may vary - this version is also 2% faster than the one I sent out as I combined all the *.c in one big file. I will email this version out when i have a chance to allfty Se subscribers. ===================================================== my version is compiled under Intel v8 with the following options: CFLAGS = /O3 /G6 /Ob2 /Gr /Qunroll /Qip /Qipo /QaxiW /W0 COPTS= /MT /DSMP /DCPUS=4 /DFAST /DVC_INLINE_ASM /DASM_INLINED /DNT_INTEREX /DFUTILITY /DEPD Best, Michael
