我们描述了UPC PGAS模型应用于NAS并行基准测试套件中的三个应用基准测试的性能研究。这项工作的重点是针对数据亲和性和数据访问所做的编程选择的性能影响。我们比较了以UPC编码的每个基准的多个版本在共享内存和基于集群的并行系统上的运行。这项研究指出了UPC的潜力以及在使用该语言时实现高性能的一些问题。
We describe a performance study of the UPC PGAS model applied to three application benchmarks from the NAS Parallel Benchmark suite. The work focuses on the performance implications of programming choices made for data affinity and data access. We compare runs of multiple versions of each benchmark encoded in UPC on both shared-memory and cluster-based parallel systems. This study points out the potential of UPC and some issues in achieving high performance when using the language.
