Abstract

Abstract: We present a benchmark suite for computational Grids. It is based on the NAS Parallel Benchmarks (NPB) and is called NAS Grid Benchmark (NGB) in this paper. We present NGB as a data flow graph encapsulating an instance of an NPB code in each graph node, which communicates with other nodes by sending/receiving initialization data. These nodes may be mapped to the same or different Grid machines. Like NPB, NGB specifies several different classes (problemsizes). NGB also specifies the generic Grid services sufficient for running the suite. The implementor has the freedom to choose any Grid environment. We describe a reference implementation in Java, and present some scenarios for using NGB.
