Is it possibly an MPI problem? What version of MPI are you using on the MAC
(I see mpich2 on ubuntu). Have you ever tried openmpi using the configure
script we provide?
If it is a compiler problem, this is a major stumbling block, since 4.4.x
is the current released compiler, and is found all over the place. Users
can mostly live without running parallel RISM, but the pmemd errors are in
bog-simple calculations that everyone will want to run. I'll see if I can try
some tests myself.
