I’m not a Fortran programmer so I’ve perhaps not as close an eye on this as other areas, however looking at the Fortran IDE FTranProjectBuilder release notes it seems there have been 17 updates in the last 12 months. FTranProjectBuilder is now up to version 1.15 with new features being added at a steady rate. Of note for scientists FTranProjectBuilder has support for two of the most common parallel processing libraries. If your program is coded for MPI using OpenMPI or OpenMP and you have them installed, you can use FTranProjectBuilder to run on multiple processors.
