The Hoffman2 Cluster is a project of the Institute for Digital Research and Education (IDRE) Cluster Hosting Program. It opened to users on January 28, 2008. The Hoffman2 Cluster is managed and operated by the IDRE Research Technology Group under the direction of Bill Labate.
UCLA’s Shared Hoffman2 Cluster currently consists of 1,200+ 64-bit nodes and 15,256 cores, with an aggregate of over 75TB of memory. Each node has 1GB Ethernet network and a DDR, QDR, or FDR Infiniband interconnect. The cluster includes a job scheduler, compilers for C, C++, Fortran 77, 90 and 95 on the current Shared Cluster architecture, applications and software libraries that offer languages, compilers and software specific to Chemistry, Chemical Engineering, Engineering, Mathematics, Visualization, Programming and an array of miscellaneous software. The current peak CPU performance of the cluster is approximately 150 Trillion Floating Point, double precision, operations per second (TFLOPS) plus another 200 TFLOPS with GPUs. Hoffman2 is currently the largest and most powerful cluster in the University of California system.
Additional Hoffman2 resources for researchers include complete system administration for contributed cores, cluster access through dual, redundant 10Gb network interconnects to the campus backbone, the capability to run large parallel jobs that can take advantage of the cluster’s InfiniBand interconnect, and web access to the Hoffman2 Cluster through the UCLA Grid Portal, as well as access to a Panasas parallel filesystem and a NetApp storage system. Current HPC storage capacity is 2 petabytes.
The cluster is also an end point on the Globus Online service using the 10Gb network interconnect backbone, thus providing researchers a facility for fast and reliable data movement between Hoffman2 and most leadership class facilities across the USA.
