Why and How Using HPC in University Teaching? A Case Study at PoliTo

After an era of “personal-computers-only”, supercomputing facilities and services are coming back to Universities to support research activities and computationally intensive simulations, but with some important differences with respect to the past. Besides the technological issues, while in the seventies-eighties the scene was dominated by mainframes, managed by skilled system managers and most of times used by operators with good computer expertise, today, the widespread and pervasive use of computers has lead to a completely different scenario. The demand for computation resources is emerging from a wide variety of areas and disciplines and mostly by users with basic expertise in computers, who however most of times request to have full control of the computation resources. Within this picture and especially at University level, High Performance Computing (HPC) has emerged as a good tradeoff to meet the different demands, and at the same offering good services at reasonable setup and maintenance costs. Traditionally, HPC has been and is being mostly used in support to applied research, but more recently some questions have emerged: - How much is it reasonable to offer HPC also to some teaching activities? What are the problems, advantages, and drawbacks? Is this the “right” way or should HPC resources be directed to research only? At Politecnico di Torino we tried to respond to these questions and started a test project called HPC-4-teaching. In this paper we present the results achieved by this project on a small set of courses during one full academic year
