Abstract

In this paper we present the results of benchmark experiments carried out on a Silicon Graphics Origin2000. We used the EuroBen Benchmark ([11]) to assess the performance of a single node and, where relevant, the performance as a shared memory system and as a distributed memory system. For relevant programs results are compared with those obtained on a Cray T3E. 1 Introduction This paper describes our first experiences with the Silicon Graphics Origin2000 system obtained through experiments with the EuroBen Benchmark ([11]). These experiments have been conducted between June and September 1997. We think that they have given us a fairly intimate knowlegde of the behaviour of the Origin2000 system with regard to its performance. The knowlegde of the system architecture together with the benchmark results also gives some confidence about predicting performances of programs that to a fair extent employ algorithms as present in the benchmark. The Origin2000 is a so-called Non-Uniform ...
