Description:
Open-source coarray Fortran ABI, API, and compiler wrapper

About:
Opencoarrays is an open-source library that extends the GNU Fortran compiler to support the coarray Fortran parallel programming model. It provides an application binary interface (ABI) and API for partitioned global address space (PGAS) programming. This allows developers to write parallel code using native Fortran syntax while the library handles communication via MPI.

Key Features:

GNU Fortran compiler extension for coarray support
Open-source MPI-based communication backend
Standard coarray Fortran API implementation
Compiler wrapper for seamless integration

Use Cases:

Parallel scientific and high-performance computing applications
Porting coarray Fortran code to systems without native support

Alternatives:

Intel Fortran Compiler – Includes native coarray support but is proprietary and not open-source.
Coarray-C – A C library implementation of coarrays, whereas Opencoarrays targets Fortran specifically.
