You mean the Paragon? Massively-parallel computing would be
ideally suited for this type of job. Each CPU grabs a chunk of the
keyspace and then works on it totally independently of all the others.
If you have a 4096-node system, with each CPU only capable of 100,000
keys/sec, you still end up with 400 million keys/sec. That would be a
match for the world-wide effort under way with the genx.net server.
