Hello Crafty Fans! My tips for this week is based mainly on older versions of Crafty. How do you get more performance out of them? #1) Recompile the source with a newer compiler. VC++ 2005 E. EdB1. You might have to experiment with the optimizations. #2) Using an SMP version of Crafty. Use the mt command to use more threads. Example: P4 (1) 3.0 Ghz, HT enabled. With the older version, 18.01 smp, do your bench with the following: mt 2 hash 96m hashp 24m cache 8m bench <Enter> Run the program again... mt 1 hash 96m hashp 24m cache 8m bench <Enter> See the difference in results? Try the single CPU version in comparison to the mt 1 benchmark. Newer versions however, 19.17, do not necessarily work the same way. In some of the older versions you could see a 300-400k nodes/second increase. Enjoy, Joshua Haglund toneewa@yahoo.com
