Mobile phones have very limited memory. On the iPhone I only have about 20 MB. This is a big limitation for UCT programs.

I am not a hardware expert, so I do not know. I took the data from the SSDF list at http://ssdf.bosjo.net/list.htm There we have 1 Deep Rybka 3 x64 2GB Q6600 2,4 GHz 3213 +25 -23 ... .. 35 Pocket Fritz 3 Hiarcs Ipaq 214 624 MHz 2722 +53 -51... I'm not trying to refute you or claim you did anything wrong. I'm just suggesting a refinement to get a more accurate estimate of how much we can expect to lose going to the mobile phone platform. My refinement is more appropriate for what to expect when porting a GO program to the mobile platform. Trying to extrapolate what I know from your data and the "rybka adjustment", you get this: As a general rule of thumb, if you port your go program to a mobile platform you will get the same performance that you would get if you played on the PC at a time control 6 or 7 times faster. So for example if you set your program to play a game in 3 minutes on the Q6600 platform and other programs are playing 20 minute games, you should come relatively close to what you can expect on the mobile platform. Don I think, this Hiarcs version was especially tuned for "limited" hardware. They probably took the program that was easiest and most sensible to port. I believe Hiarcs is 32 bit program which will port to mobile phone hardware with the least amount of ELO loss. A 64 bit program would take an additional hit in performance being ported to 32 bit hardware. Ingo PS: The reason to mention go programs for mobiles was that Valkyria's graphic seems ideally suited for small screens. -- GRATIS! Movie-FLAT mit über 300 Videos.
