Re: Question about Critter 1.6 & Gaviota gtb's

Experiment (CSS, 2006 (german magazine for computer chess))

Access time:

HDD (MHU2100AT): 20,35ms
2GB USB-stick: 2,43 ms
4GB USB-stick: 1,00 ms

-> TB acces 20x faster on an 4 GB USB-stick (today the flash memory is better)

Re: Question about Critter 1.6 & Gaviota gtb's

I would be surprised if HDD seek time beats USB2 access time. For tablebase access, seek time is what counts. USB access is 20-100x faster than HDD-access. Because of that, all TBs are very, very slow on HDDs! Of course a real SSD would perform better than a USB stick. Not sure about that. A SSD is...

Critter 1.6 and Critter 1.6a (both 3000 games)

I played 3000 games with Critter 1.6 and 3000 games with Critter 1.6a (with 20''+250ms) against 10 Top-Engines for my old LightSpeed-rankinglist (work on the new LightSpeed-rankinglist is in progress - still 14 days to go...). Overall result: Critter 1.6: 56.9% Critter 1.6a: 56.4% That is within the...

Re: Deep Saros 3.2 released

Download: http://deepsaros.jimdo.com/ Tested it in my LightSpeed-rankinglist (exact like the TEB-rankinglist except the thinking time: only 20''+250ms). And it scored 4% weaker than Deep Saros 3.0 (after 3000 games against the same opponents). So the new 3.2 will not tested in the TEB-rankinglist.....

Disappointing: +9 elo (inside errorbar). Intel i7-2630QM (SSE42 support, Windows 7 64bit, Quadcore, FritzMark=20.2), 64 M...
