Subject: AMBER: HT vs no HT

This isn't exactly the benchmark info that you were looking for, but it
might be relevant:

I compared sander running with 4 processes and HT turned on to sander
running with 2 processes and HT turned off on a dual Xeon 2 GHz. Across
the 3 or 4 benchmarks I ran, the 4 process HT method was about 10-20%
slower.

This was with ifc/icc compiled sander from AMBER 8 circa July and LAM MPI.
