The gfortran49 man page says:

            lib Library-based coarray parallelization; a suitable GNU Fortran
                coarray library needs to be linked.

Which is "a suitable GNU Fortran coarray library"?
I didn't think there was any.

Well, currently only "-lcaf_single". Unfortunately, there is currentlyno working multi-image coarray communication library for gfortran. Andalso the compiler does not yet generated all required communication calls.

The full support is planned - but it is unclear when it will becompleted. Recall, gfortran is essentially developed in the spare timeof only a few volunteers. Thus, new volunteers are highly welcome ...
