Deep Junior and >Diep are two examples that spring to mind. It is time for my next project. Today I finished the PO for a new beowulf cluster machine here. This machine will have 8 nodes, with each node being a quad xeon 550mhz machine. The nodes will be connected by a gigabit/sec switch. And no, it won't be crafty's permanent machine. But look for it to do some interesting matches on ICC later this year when I get to the distributed search. :) This is an interesting 'cluster' since it has 8 machines with 4 cpus per node. We are adding 8 more machines this Summer. It will be a horse of a box, and the initial 8-node box ought to be able to search at 8M nodes per second easily...
