Thanks for the report. It's possible that linking some shared libraries
(vs. loading static libs) could be the source, but that would be a
surprise, since none of those libraries is called much in a typical benchmark
calculation. FWIW, I don't see any speed difference between pmemd in
cmake vs legacy build -- don't know if you have tried that.
As far as I can see, the fortran optimization flags (-O3 -mtune_native)
are the same in the two builds, and I don't see obvious changes in the
link commands.
