Hi, guys!
Could somebody post a Pepito´s config.dat for 32Mb in total (including hash size, pawn hash size, eval size and egtb cache size)? Ive never understood this numbers with entries...for sure a really beast :-)
Thanks in advance

With this settings (I don't know if they make sense):
HASH_SIZE 16
PAWN_HASH_SIZE 12
EGTB_CSIZE 4
ECACHE_SIZE 4
RESIGN_MARGIN -700
EGTB_PATH g:\tb
Pepito says:
HASH_SIZE: 1048576 entries / 16.00 MB
PAWN_HASH_SIZE: 524288 entries / 12.00 MB
ECACHE_SIZE: 262144 entries / 4.00 MB
EGTB_PATH: g:\tb
RMARGIN: -700
USE_BOOK: yes
I don't know about the EGTB_CSIZE. According to the NT taskmanager
it's using 34280 KB of ram.

Hi Carlos,
Here is mine:

# Configuration file for Pepito
#
# Hash size in MB. MUST be a power of two. If set to zero, disables hashing.
# I'm not sure why anybody would want do this but... Anyway, if you're using
# book, hash size must be at least the same as book size.
HASH_SIZE 16
# Path were tablebases are located in your hard drive (if any). Set it to a
# directory with no tablebases if you want Pepito not to probe them. This
# configuration file is overriden by environment variables.
EGTB_PATH D:\sakk\tb
# Resignation margin. It's up to you to set this so high that Pepito will
# always resign. In centipawns.
RESIGN_MARGIN -700
# Pretty self-explainable. :)
USE_BOOK yes
# If this is set to no, Pepito will think of book moves as if they were the only
# legal moves and do a normal search. This should make it play into lines that
# it likes (and hopefully, plays better). My tests say this is false anyway.
BOOK_RANDOM yes
HASH_STORE_DEPTH 0
PAWN_HASH_SIZE 6
ECACHE_SIZE 8
EGTB_CSIZE 4
LOGGING yes

Note that this only adds up to 30 MB (16 min hash, 6 pawn hash, 8 evaluation hash), but there is no way to set it to 32 MB's exactly. The reason of this is that main hash and eval hash can be set only to powers of 2, while pawn hash can be set only to values such as 3, 6, 12, 24 etc.
Cheers,
Gábor

Thanks a lot, Gabor and Alfredo!! :-)
