hpc.rs.umbc.edu is a distributed-memory cluster with currently 33 compute nodes, each equipped with two dual-core AMD Opteron processors and 13 GB of memory, connected by an InfiniBand network and with an Infiniband-accessible 14 TB parallel file system. The initial purchase in 2008 pooled funds from several researchers with seed funding from UMBC. This machine will be extended over the next three years up to a total of 128 compute nodes with funding partially supported by the National Science Foundation and additional funding from individual researchers. If you are interested in joining the effort, contact the chair of the user committee: Matthias K. Gobbert (gobbert@math.umbc.edu). More information on hpc.rs.umbc.edu
