【 摘 要 】

This document outlines a proposal for extending UPC'spoint-to-point memcpy library with support for explicitly non-blockingtransfers, and non-contiguous (indexed and strided) transfers. Variousportions of this proposal could stand alone as independent extensions tothe UPC library. The designs presented here are heavily influenced byanalogous functionality which exists in other parallel communicationsystems, such as MPI, ARMCI, Titanium, and network hardware API's such asQuadrics elan, Infiniband vapi, IBM LAPI and Cray X-1. Each sectioncontains proposed extensions to the libraries in the UPC LanguageSpecification (section 7) and corresponding extensions to the GASNetcommunication system API.
