So compare Slates dual 2100+ (1.73Ghz) getting a 1.68x speedup with Crafty v18.11 and 1.69 million nodes/sec to your other P4 systems. :) the 2400+MP chips are already out, too.. Dual 2400+ should pull right under 2 million nps. If for some reason you'd like the "1.7x dual amd" binary, grab it at: ftp://speedycpu.dyndns.org/pub/crafty/c1811smp-k7sse.zip >>>>>If I recall, the 4=way dual 2.0ghz xeon is the fastest PC-class machine around >>>>>right now, >>>>>by a wide margin.
