Portals 4.0 Implementations

Reference Implementations

• Reference implementation developed through collaboration between Sandia National Laboratories and System Fabric Works. Supports InfiniBand and shared memory, utilizing a progress thread for each process: Portals 4 reference implementation
• Reference implementation over UDP developed by Eviden (Atos): Portals 4 reference implementation

Shared Memory Implementation

The earliest reference implementation of Portals 4.0 was over shared memory only, and was optimized to examine overheads in the Portals semantics relative to other messaging interfaces. While the code can be found on the Portals 4 Google Code page, the implementation has been deprecated in preference to the reference implementations.
