Large Scale Cluster Computing Workshop Fermilab, IL, May 22nd to 25th, 2001 Proceedings 1.0 Introduction Recent revolutions in computer hardware and software technologies have paved the way for the large-scale deployment of clusters of off-the-shelf commodity computers to address problems that were previously the domain of tightly-coupled SMP computers. As the data and processing needs of doing physics research increases while budgets remain stable or decrease and staffing levels only incrementally increase, there is a fiscal and computational need that must be and that can probably only be met by large scale clusters of commodity hardware with Open Source or lab-developed software. Near-term projects within high-energy physics and other computing communities will deploy clusters of some thousands of processors serving hundreds or even thousands of independent users. This will expand the reach in both dimensions by an order of magnitude from the current, successful production facilities. A Large-Scale Cluster Computing Workshop was held at the Fermi National Accelerator Laboratory (Fermilab, or FNAL), Batavia, Illinois in May 2001 to examine these issues. The goals of this workshop were: To determine from practical experience what tools exist that can scale up to the cluster sizes foreseen for the next generation of HENP experiments (several thousand nodes) and by implication to identify areas where some investment of money or effort is likely to be needed; To compare and record experiences gained with such tools; To produce a practical guide to all stages of designing, planning, installing, building and operating a large computing cluster in HENP; To identify and connect groups with similar interest within HENP and the larger clustering community. Computing experts with responsibility and/or experience of such large clusters were invited, a criterion for invitation being experience with clusters of at least 100-200 nodes. The clusters of interest were those equip
