Re: [computer-go] correspondence or turn-based servers
Some Go players do use computers do analyze correspondence games. Computer Go play in general is nowhere close to dan-level play, but a computer program can read out smaller tactical problems with a very high level of accuracy. Does such play have anything to do with the real game of chess or Go? In a sense, it might be considered a striving for kami no itte - the hand of god or the perfect play.

Also, opening novelties and ideas found in postal chess can be used in real games. And you probably can't tell the difference just by looking whether a game was played over the board or by postal chess. I say probably because I have heard than most top players go for very sharp interesting lines and complexities. But so do some strong over the board players. - Don ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
[computer-go] July KGS Computer Go tournament: small boards, fast
The July 2007 KGS computer Go tournament will be on the second Sunday in July, July 8th, in the Asian night, European afternoon and American morning, starting at 16:00 UTC (GMT) and ending soon after 18:30 UTC (GMT). The Formal division will be an 8-round Swiss with 9x9 boards and 8 minutes each sudden death. The Open division will be a 5-round Swiss with 13x13 boards and 13 minutes each sudden death. Both will use Chinese rules with 7.5 points komi. There are details at http://www.gokgs.com/tournInfo.jsp?id=300 for the Formal division, and at http://www.gokgs.com/tournInfo.jsp?id=301 for the Open. Registration is now open. To enter, please read and follow, as usual, the instructions at http://www.weddslist.com/kgs/how/index.html. The rules are given at http://www.weddslist.com/kgs/rules.html. As for the June event, please send it (with the words KGS Tournament Registration in the title as usual) to me at maproom at gmail dot com (converted to a valid address in the obvious way).

Re: [computer-go] CGOS 19x19
I think it's a server bug. It doesn't know what to do when only 2 program are playing. I restarted the gnugo anchor. - Don On Thu, 2007-06-28 at 22:37 -0400, Don Dailey wrote: It looked somehow wedged, but I restarted it.

Re: [computer-go] MPI vs. threads

I would suggest you use MPI if you already know and like it, and use threads if you already know that. If this is an opportunity to learn, then I'd learn threads for a single multicore machine. The usage of MPI that I've seen required explicit population of (user-defined) communication structures that get copied in the process of doing an MPI call. This is true and something we tried to put some wrappers around to simplify, but this underlying fact could not be removed. I think it is a pain that whenever we want to modify the message we have to go down a few layers and tell MPI the number of integers and floats we are going to pass. It led to a few debugging headaches when we started, but we are used to it now. Whenever a struct changes we check to see if it is in any messages. But SlugGo runs on a cluster of many boxes, so threading is not a choice for us. But once the code uses MPI, it works just fine across the network or in the same CPU. I really didn't want to manually specify, populate, and then read out data for any given inter-process call. I ended up using delegates / functors for inter-process communication and restricted the bot to threading to keep the work to implement it simple. Maybe after doing enough multi-threaded programming I'll come to realize that MPI isn't much of a cost and shift my IPC design to use MPI. In the mean time, I'm comforted that allowing slug go support can bridge the gap if needed. What about if a heavy playout algorithm is using a pattern library too big to fit in the cores local cache? Would that change the MPI vs. threads decision? Not to me. Cheers, David ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
