Design, Deployment and Bench of a Large Infiniband HPC Cluster

This paper provides an overview of the Universite de Sherbrooke (UdeS) experience, in terms of design, deployment and bench of a large InfiniBand HPC cluster. In particular, attention is focused on tuning MVAPICH and the linpack benchmark in order to achieve 83.9% of the theoretical peak, which is usally reserved for high end proprietary clusters.
