Is this because of the new SMP stuff or changes to >the evaluation? Did you do the compile? I didn't notice any changes at all on my box at the office between 19.19 and 19.20. However there are eval changes, so if you are just looking at total time, it might be slower, because the tree could be bigger due to many of the eval changes... I generally watch raw NPS for speed comparisons... > >regards >Andy > >--------------------------------------- > >System uname: 2.6.12-gentoo-r6 x86_64 AMD Athlon(tm) 64 Processor 3400+ >(default-linux/amd64/2005.0, gcc-3.4.4, glibc-2.3.5-r1, 2.6.12-gentoo-r6 x86_64) > >same compile options: > >linux-amd64: > $(MAKE) target=LINUX \ > CC=gcc CXX=g++ \ > CFLAGS='$(CFLAGS) -Wall -pipe -D_REENTRANT -march=k8 \ > -fomit-frame-pointer -O3' \ > CXFLAGS=$(CFLAGS) \ > LDFLAGS='$(LDFLAGS) -lstdc++' \ > opt='$(opt) -DFAST -DFUTILITY -DINLINE_AMD' \ > crafty-make > > >%crafty19-19 >unable to open book file [./book.bin]. >book is disabled >unable to open book file [./books.bin]. > >Crafty v19.19 > >White(1): bench >Running benchmark. . . >...... >Total nodes: 96761642 >Raw nodes per second: 2199128 >Total elapsed time: 44 >SMP time-to-ply measurement: 14.545455 >White(1): quit > >%crafty19-20 >unable to open book file [./book.bin]. >book is disabled >unable to open book file [./books.bin]. > >Crafty v19.20 > >White(1): bench >Running benchmark. . . >...... >Total nodes: 86620029 >Raw nodes per second: 1924889 >Total elapsed time: 45 >SMP time-to-ply measurement: 14.222222 >White(1): quit
