Abstract:   In this BoF, the new GASPI API specification and its reference implementation based on the Fraunhofer PGAS communication library GPI are released. As such, industry proven scalability, flexibility and fault tolerance on large scale heterogeneous systems are addressed. We present the small, yet powerful API composed of synchronization primitives, synchronous and asynchronous collectives, fine-grained control over one-sided read and write communication primitives, global atomics, passive receives, communication groups and communication queues. We show performance results and discuss fault tolerance of GASPI conform applications, especially in the industrial set up. We believe that many of the features in GASPI are unique and are of paramount importance to any next-generation API for exascale architectures. Specifically, GASPI offers support for asynchronous data-flow programming models on distributed memory architectures. In this BoF, we would like to engage the discussion about these features and we are looking for possible collaboration.
