It's taken quite awhile but I'm looking forward to getting the board. I hope there are decently mature go binding because that would be incredible to have a goroutine coprocessor.

Both MPI and OpenMP are fairly mature and easy to use with C or C++ (I haven't used them with FORTRAN, but I believe you can, with a few slight alterations).
