[CoArray Fortran Framework of Efficient Interfaces to Network Environments (Caffeine)](https://github.com/rouson/caffeine): parallel runtime library that aims to support Fortran compilers with a programming-model-agnostic application binary interface (ABI) to various communication libraries, by Damian Rouson et al. Current work is on supporting the ABI with the GASNet-EX or with POSIX processes.
