摘要: The industry-standard Message Passing Interface (MPI) provides one-sided communication functionality and is available on virtually every parallel computing system. However, it believed that MPI's model not rich enough to support higher-level global address space programming models. We present the first successful application of MPI as a runtime system for PGAS model, Global Arrays (GA). This work has an immediate impact users GA applications, such NW Chem, who often must wait several months year or more before becomes new architecture. explore challenges in MPI-2 models motivate features upcoming MPI-3 standard. performance our evaluated popular high-performance architectures through benchmarking using Chem computational chemistry suite.
