I want to play a 100 game match (with the 50 gambit positions) between SF13 and the Dragon (the obvious leaders on the GRL) using 20 cores, TC=10m+10s (average 15-20 seconds per move) then what would be the ideal hash table size for such a setup, 1Gb, 2Gb, 4Gb? Never done this before. Match will run using my improved webmatch util (live broadcast eng-eng matches) currently in beta test at:

How much RAM have you got in total?

16Gb on one, 32Gb on another.

with 20 cores and 10s increment id go with 2-4GB, probably 4GB but im not very experienced in eng vs eng matches

What is the hardware that can run 20 threads ?

It's 10 cores not 20, there is a big chance that running the engines with 20 threads on this hardware will only weaken them.

It's 2x10 cores, 20 cores, 40 threads

Looking forward to the match.

Then it is a dual processor system, this was not clear from the link you posted.

It says:

. Hardware : Intel Xeon E5 2680 v2
. Frequency : 2.8 - 3.6 Ghz
. Used cores : 20

Shouldn't it be:

. Hardware : 2 x Intel Xeon E5 2680 v2
. Frequency : 2.8 - 3.6 Ghz
. Used cores : 20
