I have put a report of the weekend's challenge games between MoGo and Catalin
Taranu 5p at http://www.computer-go.info/tc/
mainly to make it easier for people to find the game records.
Thanks a lot for that.
Some points are wrong however, below some informations about the errors.
The hardware was provided by Bull and operated by Bull; we have never
had an access to the hardware ourselves, in the mogo-team.
Only the solution
used when the initial hardware was down was operated by me. The hardware
used for calibrating comes from Grid5000, but as Grid5000 does not agree
for the use of its hardware for Go competitions, it was only for
calibrating and experimenting.
The hardware in case of trouble,
which has been used for two games, is provided by Université Paris-Sud.
The code was originally written by Sylvain Gelly and Yizao Wang, with
ideas from Remi Munos and minor contributions from me. Rémi Coulom
has also helped the initial developments and we had some discussions
with him at various steps of the development. Then, the
code has been improved by Arpad Rimmel, Jean-Baptiste Hoock, Julien Perez
and me. Thomas Herault and Vincent Danjean also helped for profiling
various aspects of the parallelization.
This is a small list of contributors, as we have opened the cvs
access to many people and many people have suggested or coded some
points: a complete list of contributors is in
http://www.lri.fr/~teytaud/crmogo.html (in french, an english version
should come soon). This web page is itself a draft, in progress; I'll
include more informations later.
For the first game, the game was played by the cluster from Bull during 13
moves, then the cluster was down (hard drive full). I then launched the
second machine, a 4-core system.
For the second and third game, the game was played by the cluster with
no bug; one win for Catalin, one win for Mogo.
For side games, played around the challenge against Catalin, there was no bug;
mogo won both times.
In 19x19, the cluster lost its connection to internet and therefore I
launched once again the second solution. The cluster came back later in
the game. I am not able to remember at which times (perhaps in the KGS
record).
In my humble opinion, there was no problem for the clock in 9x9 games;
only in 19x19, we were afraid that the KGS time might be different
from the physical clock, but the trouble was minor as mogo resigned before
any trouble.
Thanks,
Olivier
