Subject: 8 game match 34 game total Crafty vs CT13

Author: Paul Doire

Hardware: 541Mhz Celeron  128 MB Ram
5 and some 6 man tablebases
Hash: Chess Tiger 13=                              48 MB RAM
Crafty.rc: hash 24,hashp 20,cache 4=               48 MB RAM

Excerpt from Crafty.doc:

"The only thing to watch for is that if you make hashp too large,
 particularly under Windows, performance  will  suffer  badly
 because  of paging I/O overhead. When Crafty is searching in
 a normal (non-book, non-endgame database) position, the disk
 light should *not* be on, indicating lots of I/O.

 There  is no danger in making the pawn structure/king safety
 table too large, although if Crafty barely fits  in  memory,
 doing  something  else on the machine can cause Crafty to be
 swapped out completely or partially, depending on the  oper-
 ating  system  you  are  using."

The disk light was never on!!
