Steve (et alia),
Is it possible for a non-Coarray Fortran program to launch a Coarray Fortran? Can a Coarray Fortran image launch other Coarray Fortran images? I'm imagining using RUNQQ() in both cases. We are exploring some (perhaps unconventional) ways to parallelize very large sections of engineering code. These ideas arise from the need to very carefully balance work load between Coarray images if full efficiency is to be obtained.
