An evaluation of the performance of VGTU PC cluster

Abstract

In this work we have tested the performance of VGTU PC cluster "Vilkas" in order to identify the main characteristics of the system and to nd for what type of computational jobs the cluster is well adopted. HPC Challenge suite of benchmarks was used for that purpose. The results of tests are presented and discussed. We analyze the in uence of di erent compilers and hyper-threading technology on the performance of the cluster. Some recommendations for future upgrade of the system are given.
