Why Komodo 9 support only 16 GB hash ?

[Vinvin]

16 GB is quickly filled with 16 cores.
64 GB should be a minimum in 2015 !

Komodo 9 does support up to 64 GB hash tables (in linux, Mac and Windows 64 bit compile). In 32 bit mode, the memory models do limit it to less. But you really should run Komodo in 64 bit mode. Note that older versions of Komodo did have the 16 GB limit. I try to adjust things as computers improve.

Unless you are doing a really long (multiple day) search for (perhaps) correspondence chess or deep analysis, searches with 64 GB will fare much worse than smaller hash tables.

Of course, the exact performance will depend on the system since on chip cache varies a lot from machine to machine.

Good to know, you should ask Chessbase to correct here : http://shop.chessbase.com/en/products/k ... 5OH0EFN840

The Komodo 9.02 engine which can support up to 64 processor cores and 16 GB of hash memory

Why 64 GB should slower than 4 GB ?
64 GB should be filled in less than 30 min on 16 cores.
For an overnight analyze, we need more !

yeah, what happens if I get a 32 core machine? I suppose I'll have to use an 8GB hash for better performance?

I could fill up 16GB hash on my i7 4 core rather quickly. IF I had a 16 core I would get at least a 128GB for optimal results.
