Lubos -
If you really need this, for pmemd just edit get_cmdline.f90 to
include -execer_id as something that is filtered out in the mpi code. First
grep for "-np", see what is done to filter it out, and do the same thing
for -execer_id. You can do the same thing in sander; the relevant code is
in mdfil.f.
Regards - Bob
