We also mention the knowledges obtained through these experiments about parameter tuning for better HPL performance. ![]() In this paper, we present the combination of parameters we used when Xenia got the 195th place on 20th Top500 Supercomputer Sites, and show how to tune the parameters. It is possible to get better performances through ne-tuning of parameters, but it is dicult to determine the best, because HPL has a wide range of parameter selections. We evaluated the cluster system using HPL, which is an implementation of LINPACK benchmark, which is widely used for evaluating performance and is introduced in the TOP500 Supercomputer Sites. At Intelligent Systems Design Laboratory, we install an HPC cluster system called Xenia which is a 64-node cluster running Linux Operating System. HPC cluster systems are attractive to the scientist and engineers who are need of high-performance computations. PC cluster systems consist of many PCs connected by network and are used for parallel or distributed computations. Due to recent improve performance of widely available personal computers, PC cluster systems attract attention than high performance vector supercomputer.
