No... it was not 18.15. I had written "this is the latest version" but I
somehow deleted that when cutting/pasting the actual output.  I'll try to
compile 18.15 and test it...

Here is the same test for 18.15.  Machine = 2.8ghz dual xeon, 1.0gb DDR RAM,
one processor without SMT and two processors with SMT enabled.

Total nodes: 97487547
Raw nodes per second: 1107813
Total elapsed time: 88
SMP time-to-ply measurement: 7.272727


Total nodes: 118365893
Raw nodes per second: 2156433
Total elapsed time: 59
SMP time-to-ply measurement: 10.666667


Again the last run was averaged over four separate runs of the bench
command, for those that like to forget that I do this most every time.
