DescriptionOpenSHMEM is a PGAS API for single-sided asynchronous scalable communications in HPC applications. OpenSHMEM is a community driven standard for this API across multiple architectures/implementations. This BoF brings together the OpenSHMEM community to present the latest accomplishments since the release of the 1.4 specification, and discuss future directions for the OpenSHMEM community as we develop version 1.5. The BoF will consist of talks from end-users, implementers, middleware and tool developers to discuss their experiences and plans for using OpenSHMEM. We will then open the floor for discussion of the specification and our mid-to-long term goals.
