Hi David,
You are probably right, then. Since I don't officially support either
OpenMPI or g95, I could see potential mix/match grief if there are some
other issues, but where the fortran compiler is complaining about void *
stuff, well that is just nonsense. For pmemd, I don't support module
interfaces to the mpi stuff and just carefully check any calls I code - I
can get away with that since I am the only guy in the code, and it
simplifies life where the module interfaces may not be readily available.
So I would say run it, and if it blows up, we look for mismatched default
types. Arturo, if you have trouble with running pmemd, then send me the
compiler listing.
Regards - Bob
