That's the most remarkable crosstable I've ever seen (in Shahrokh's
link). The players are essentially well-ordered; the top beat everyone,
2nd beat everyone except 1st, 3rd beat everyone except 1 and 2, etc,
all the way down. It makes a upper-trianglular matrix. Remarkable.<br>

I used to give 13 stones to ManyFaces on my own PC. I suspect this beast, on that cluster, could give me several.<br>
I still give 6 to programs running on just PCs.<br>
(3 stones is about knight odds, in chess terms)<br>

On a related note, at the same tournament, the cluster version of "Many
Face of Go" has won the Gold medal in both 9X9 and 19X19 categories
with no defeats. Go is notoriously harder than Chess for
computers to play as you might now. The results are here:<br> <br> <a href="http://www.grappa.univ-lille3.fr/icga/tournament.php?id=181">http://www.grappa.univ-lille3.fr/icga/tournament.php?id=181</a><br> <br>
incidentally, the code was running on a Windows HPC Server 2008, 32
core intel cluster (we helped the author port/tune his MPI code a
little).<br> <br> For some info re challenges in computer Go see:<br> <br> <a href="http://en.wikipedia.org/wiki/Computer_go">http://en.wikipedia.org/wiki/Computer_go</a><br> <br> <br> Shahrokh<br> <br> <br> <br> From: <a href="mailto:beowulf-bounces@beowulf.org">beowulf-bounces@beowulf.org</a> [mailto:<a href="mailto:beowulf-bounces@beowulf.org">beowulf-bounces@beowulf.org</a>] On Behalf Of Peter St. John<br>

The World Computer Chess Championship is onging in China (part of the
World Mind Sports thing). The leaders, about half-way through , are a
40 core cluster from the US and a "8 x 4GHz" machine from the UK, with
4.5 out of 5. There are 10 participants, it's a nine-round round robin.
Cluster Toga, also a cluster, is notable for drawing both of the
leaders.<br> <br> >From <a href="http://www.chessbase.com/newsdetail.asp?newsid=4935">http://www.chessbase.com/newsdetail.asp?newsid=4935</a><br> Rybka<br> USA<br> Cluster, 40 cores 3.5 4 5.0 4.50<br> Hiarcs<br> GBR<br>
