RAPIDROID RELOADED: September-2015 with Komodo 9.2

Although this release took a few days of delay, it was just because of a hard working week. Anyway, i believe the improvements compensate largely.

The highlights of this release are:

* UPDATED Komodo 9.1 to Komodo 9.2

* UPDATED Zurichess Basel to Zurichess Fribourg

* ADDED Fridolin 2.0.0

* ADDED Rybka 2.3.2a MP as new Windows engine

* ADDED The King 3.50 x64 as new Windows engine

* ADDED Novag Secondo as first tabletop computer engine

* ADDED 50 ELO to all Android engines for better calibration

THE TOPPER:

Komodo 9.2 is clearly stronger than 9.1, in contrast to my initial expectations. After a short hesitation, i replayed all previous Komodo games and 9.2 proved itself. It seems the reptile will stick to the top for a while, at least until Stockfish 7 kicks in.

As mentioned previously, the list needs good calibration vs CCRL and SSDF to be as readable as possible. I always knew it's very complex without the same hardware configuration for Windows engines and use them as trustable calibers.

AMD Athlon x2 4600+ used by CCRL and Intel Quad Core Q6600 used by SSDF have both disappeared. The only solution remaining is to find an acceptable correlation between my Intel Core i7-620M, which has also disappeared from the market long ago.

Past comparisons in benchmarking sites and some available tools show that i7-620M performs better than Athlon and slightly lower than Q6600 with MP. Therefore Windows engines must collect as much ELO as in CCRL but not more than SSDF when tested against Android engines, simply and logically.

Remote connection feature of Chess for Android worked well between Samsung Galaxy Note II and my notebook except for the gauntlets. No way to run like this.

I've had to alter my pairing method to increase automation, by playing vs each Android opponent one by one in separate gauntlets using a collection of related openings instead of consecutive rounds with various opponents using same opening for whole round.

The network engine feature works okay but needs improvement to become more effective. That's a topic i'll come back to in details in a future post.

WINDOWS CALIBERS:

Both Rybka and The King seemed to have some flaws in the calibration task:

Rybka uses hypertrading in MP mode. HT divides each physical core to two logical threads and virtually doubles the total number of threads. Unfortunately, the increase in nodes per seconds doesn't deliver the expected strength increase. HT is not efficient when used with chess engines. I've chosen to tolerate the efficiency loss in Rybka case and keep following because on my notebook there's no option to disable HT via BIOS.

The second caliber is The King. It works well under Arena as a Winboard engine via KingUCI.exe which acts as wb2uci interface. Threads and hash are selectable via wb2uci.eng but strangely the engine hogs the CPU for no reason unless i run it with only 1 thread ouf 4 available. When i use all 4 threads, 3 of them stay loaded after King makes its move. I made sure it's not because of pondering because Fritzmark running in parallel hits the usual score. There must be something wrong keeping the "freed" threads busy. Since it's not comfortable to hear the cooling all the time, relying on 1 CPU rating of CCRL looks better. However, i suspect 1 thread out of 4 on my notebook is not exactly the same as 1 core out 2. It should be something between 0.5 to 1 CPU.

Finally, i've decided to add 50 ELO to all Android engines. Rybka and The King are both ranked well within acceptable error margins for the moment.

In next steps, i'll need some single thread Windows engines to bypass the hyperthreading effect and compare better with other rankings.

SWEET MEMORIES:

If one wonders why Novag Secondo is in the list as one the weakest dedicated chess computers ever sold, i must state it's a very old friend to me. It was my first chess computer in 1993 and still works without problem in 2015!!!

So i could not keep myself from putting it into the pit after all these years. After all, my retro companion needs more weak opponents to move forward a little bit.
