Linpack HPL Performance on IBM eServer 326 and xSeries 336 Servers

Overview This paper examines the performance of the Linpack benchmark on IBM eServer 326 (e326) and IBM eServer xSeries 336 (x336) systems. The e326 is powered by AMD Opteron processors, and the x336 is powered by Intel Xeon processors. In this paper, system factors are considered that affect benchmark performance, such as processor and network performance, and the paper shows that it is not sensitive to memory performance. The paper also considers ways to tune the benchmark. In particular the paper examines what are good values for P, Q, N, and NB, and concludes that optimal values for NB must be determined through experimentation, although many values of NB can be eliminated through simple analysis.
