摘要： Methods, apparatuses, and computer program products for endpoint-based parallel data processing with non-blocking collective instructions in a parallel active messaging interface (‘PAMI’) of a parallel computer are provided. Embodiments include establishing by a parallel application a data communications geometry, the geometry specifying a set of endpoints that are used in collective operations of the PAMI, including associating with the geometry a list of collective algorithms valid for use with the endpoints of the geometry. Embodiments also include registering in each endpoint in the geometry a dispatch callback function for a collective operation and executing without blocking, through a single one of the endpoints in the geometry, an instruction for the collective operation.

摘要： Systems, methods and articles of manufacture are disclosed for effecting a desired collective operation on a parallel computing system that includes multiple compute nodes. The compute nodes may pipeline multiple collective operations to effect the desired collective operation. To select protocols suitable for the multiple collective operations, the compute nodes may also perform additional collective operations. The compute nodes may pipeline the multiple collective operations and/or the additional collective operations to effect the desired collective operation more efficiently.
