Reference 331 Activate starts the dialog for the program activation. Activate Offline starts the dialog for the program activation on a computer without Internet access. Deactivate deactivates the selected program version. 3.12.8 Improve the responsiveness of the computer while the engine runs There are several ways to keep your computer more responsive while Kommodo is thinking: Run the engine at “Lower than normal” priority. Most chess GUI will provide this option, for example: Fritz/ChessBase has a "Priority Below Normal" checkbox in the dialog for creating the UCI engine. If you want to use your computer for other purposes while analyzing chess positions, set the "Threads" configuration option to a value smaller than the the number of physical cores of your computer - for example, use 3 on a quad-core computer. This will leave one core available for other applications while the chess analysis runs in the background. 3.12.9 Which Hash Size should I use at various time controls? Forinfinite analysis or long Time Control matches you should use the largest hash possible - typically about half of the total RAM memory of your computer. For example, on a system with 4 GB of memory you can use up to 2048 MB hash size, on a 12 GB RAM system you can use up to 8192 MB. For shorter games, e.g. 3 to 5 minute games, it’s better to use 256 MB or 512 MB as this will provide the best performance. For 16 min games 1024 or 2048 MB hash size should be fine. If you know the average move time T (in seconds) and the average node speed of your hardware S (in kN/s), you can compute the optimal hash size with the formula: (T x S / 100) MB. For example if you use a Time Control of 10 minutes for 40 moves repeating, the average move time T = 15 seconds. On hardware that produces about 2,000 kN/s the optimal hash size would then be approximately (15 x 2,000 / 100) = 300 MB, in other words 256 MB or 512 MB would be the recommended values. 3.12.10 Deep Position Analysis feature If you use the Deep Position Analysis feature, it is possible that Kommodo analysis went down risky lines without taking note of drawing/equalizing chances almost every move. Is that to be expected? If you want Kommodo to favor drawing lines, you should consider putting Houdini's "Contempt" value to 0. © ChessBase 2015
