Komodo 4 32 bit re-compile

We have found the problem with the 32 bit compile of Komodo 4 and have made a corrected version, to be called version 4c2 (for second compile, 32 bit only). This version, while still a bit under half the speed of the 64 bit version, should be comparable in true speed to Komodo 3 32 bit, allowing for...

Re: Testing Komodo4

Hi Larry, I am conscious about the difference between these two tests. This is the reason I have started a 80 test (x 2 computers = 160 games) at 25 minutes per game with no increase of time, against the same opponents. The difference between SSE and no-SSE is about 14% in one of my computers and 1...

Thanks, but could you tell us what Komodo 3 does on the same hardware? It should be in the 140-150 range unless something is wrong with Komodo 4 32 bit.

Re: Don- Don't understand Komodo 4?? A bug??

Komodo 1.3 and 2.03 32bit in 40/3 repeating both average somewhere between 270kn and 350kn- nodes per second. Still in 40/3 repeating, Komodo 3 averages around 170 to 220 kns But with Komodo 4, again 32bit and 40/3 repeating, the node count drops to between 70kns to 85 kns. I have yet to see Komodo...

Re: Komodo 4 SP released!

It is certainely worth $20 if it is the new king of the hill :) But is it so? We have yet to see the first reports to surface... Then, the next Critter is around the corner and maybe Houdini had some spare reserve to produce. Interesting times I think $20 for number 2 is still a very good deal, if ...

I would have hopped to read a feedback from the Komodo team.

Are they waiting on Vas to make a move ?

Re: Komodo 4 SP released!

I have no objections to a commercial MP Komodo, and have every intention to purchase it, but I wonder what prompted the decision to go commercial on the SP version as well? I understood that SP Komodo would remain freely available. It is still effectively free for someone planning to buy the MP ver...

Re: Testing Ivanhoe B46fb at 1 hour/game.

I'm always glad to see engines tested at longer time controls, but I would just like to make one point about it: when you test closely related engines like the four you are now testing, there is no reason to expect a significant difference in "scaling"; how much each benefits from additional time. ...
