Clusters, built using commodity-off-the-shelf (COTS) hardware components and free, or commonly used, software, provide an inexpensive computing resource to educational institutions. In the Department of Informatics of T.E.I. of Athens, we have built a dynamic clustering system consisting of a Beowulf-class cluster and a NoW. The technical details of the system, as well as the experience gained in constructing the dynamic clustering system have been presented in a previous paper. The goal of constructing this system was to build an non-expensive computing resource and use it as an educational and research infrastructure. In this paper, we evaluate the use of the dynamic clustering system, as a platform for running the laboratory work of various courses (parallel computing, operating systems, distributed computing), as well various parallel applications in the framework of research, which is in progress under the programme “Archimedes”.
