Over the last decade, a dramatic increase has been observed in the need for generating and organising data in the course of large parameter studies, performance analysis, and software testings. We have developed the ZENTURIO experiment management tool for performance and parameter studies on cluster and Grid architectures. In this paper we describe our experience with ZENTURIO for performance and parameter studies of a material science kernel, a three-dimensional particle-in-cell simulation, a fast fourier transform, and a financial modeling application. Experiments have been conducted on an SMP cluster with Fast Ethernet and Myrinet communication networks, using PBS (Portable Batch System) and GRAM (Globus Resource Allocation Manager) as job managers.
