MPISOURCE

MPISOURCE is a community-driven online resource that serves as a repository and distribution hub for MPI (Message Passing Interface) source code and related materials. The project aggregates source trees, patches, build instructions, tests, and documentation to support developers, researchers, and educators working with MPI.

Scope includes major MPI implementations and related libraries, enabling access to historical versions, reference code, and platform-specific notes. While not all MPI projects are hosted exclusively on MPISOURCE, the site aims to be a centralized index and download point, often linking to official repositories while curating patches and compatibility notes.

Typical workflows include browsing version histories, downloading tarballs, or cloning via Git, applying patches, and participating in discussions or issue trackers. MPISOURCE may host or link continuous integration results, performance benchmarks, and portability tests to help users gauge compatibility across platforms.

Governance is usually community-led with volunteer maintainers and a governance policy that guides contribution, review, and release processes. Licensing is variable, reflecting the open-source licenses used by constituent MPI implementations, commonly including permissive and copyleft options.

Impact and usage: It is used in research, education, and HPC practice as a reference point for MPI source availability and interoperability. Critics note that reliance on a single aggregation point may obscure provenance; users are encouraged to verify licenses and source integrity.
