Hi Kevin,

This shouldn't matter. Bob has done a LOT of work on PMEMD to make it fully
compatible with sander and results should be identical although when running
in parallel different summation orders can lead to round off differences.
However a test case run with PMEMD should pass when compared using dacdif
against a test case save file generated with sander and vice versa. Indeed
the tip5p test case passes on my machine with both sander and pmemd so I
think what you are seeing is just your compiler rounding things in a
different way that as Dave says for a very short run can give marked
differences in the RMS.
All the best
Ross
