DURHAM UNIVERSITY SELECTS ROCKPORT SWITCHLESS NETWORK FOR LARGE-SCALE ASSESSMENT ON ONE OF ITS DIRAC FACILITY HPC CLUSTERS

Durham University , one of the UK ’ s leading HPC research facilities , has chosen 232 nodes of its COSMA7 DiRAC system for a test deployment of a new Rockport switchless network architecture which , based on codes , is seeing a performance improvement over InfiniBand . The Arepo cosmology code saw up to 28 % performance improvement over a comparable EDR InfiniBand network when running on a small test cluster . By conquering congestion – a workload killer – the university hopes to speed up research results with more predictability , better resource utilisation and economic efficiency . Alastair Basden , DiRAC / Durham University , Technical Manager of COSMA HPC Cluster , tells us more and explains the necessary priorities in the design and build of a data centre and how this contributes to uptime . urham University ’ s

Institute for Computational Cosmology ( ICC ) has selected the Rockport Switchless Network as part of the ExCALIBUR programme around new networking technologies for a test deployment on its COSMA7 supercomputer , part of the DiRAC HPC facility . For the first time , the COSMA7 cluster and its 232 Rockport nodes will provide Durham University , DiRAC and the ExCALIBUR programme with insight into the benefit of potentially reduced congestion as they model exascale workloads and use codes to run on future exascale systems . www . intelligentdatacentres . com
