Bob, you might be interested to find out what the SMP speedup on my Dual Xeon is. The single CPU Crafty 19.13 (P. Skinner) gets 988,403 kns on a single Xeon 2.4. The dual CPU Crafty 19.13 goes up to 1880052 kns. The speedup, rounded off to "only" six decimal places, is 1.858249. More raw data for you :-)
