I have tried Jeff's code and the next GM message sent is effectively garbage, so the barrier hangs. It works fine in C, though. BTW, the full fork support in Linux is provided by gm-1.5.2 that should be released today or tomorrow (we are at the release candidate 4). I have tried the same fortran code with this GM release and it works fine. I will see with our Linux guru why vfork in Fortran is not working properly, actually it works but it has a bad side effect on GM.
