My guess is that it weighs a few thousand pounds.  Here are Ulf Lorenz's papers:

Here is his computer chess page:

Here is a rough description:

And the blurb from IPCCC:
"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."
