Yes great performance by P. ConNers in this tournament , beating Dautov (2606)
today .I remember that it score 4.5/7 at Paderborn earlier this year.This is a
brief description i found but don't know if it is still valid as for hardware
equipment:

P.ConNerS
P.ConNerS stands for 'Parallel Controlled Conspiracy Number Search'. It has been
written by Ulf Lorenz, who is a member of Prof. Dr. Burkhard Monien's research
group at the University of Paderborn. U. Lorenz mainly works on the research
fields of domain independent selective search in game trees, and on the field of
efficient parallel algorithms for optimization problems. P.ConNerS uses a
variant of the so called 'Controlled Conspiracy Number Search' algorithm. As a
result it examines highly selective and irregular game trees. Evaluations are
done by the help of depth 2 alphabeta searches. When it runs on a parallel
machine with 60 Pentium 300 MHz processors, P.ConNerS reaches a rate of about
1.2 million nodes per second. In February 1999 it won the 8th International
Paderborn Computer Chess Championship.
