FortranM is a computer language for modular parallel programming.[1][2] Its syntax is based on Fortran but has additional elements such as channels and ports for communication between processes.[3]
The language was designed by K. Mani Chandy's group at Caltech, along with an Argonne national labs team. [3] The compiler for the language is freely available from Argonne labs.[3]
In FortranM processes communicate by sending and receiving messages on channels.[3] Processes and channels can be dynamically created, but programs remain deterministic.
