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 Lisa Snyder.
UCLA’s Shared Hoffman2 Cluster currently consists of 1,300+ 64-bit nodes and over 20,000 cores, with an aggregate of over 50TB of memory. Each node has 1GB Ethernet network and a DDR, QDR, FDR, or EDR 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 shared cluster in the University of California system.
Additional Hoffman2 resources for researchers include complete system administration for contributed cores, cluster access through dual, redundant 100Gb network interconnects to the campus backbone, the capability to run large parallel jobs that can take advantage of the cluster’s InfiniBand interconnect, and access to a Panasas parallel filesystem and a NetApp storage system. Current HPC storage capacity is 2 petabytes.
New User Registration
For new user registration, please follow the following two steps in order to create a Hoffman2 account.
1. New User Registration <- Click Here!
When you click on this link, your session will be redirected to the UCLA Federated Authentication Service so that you can authenticate yourself as a member of the UCLA community. To do so you will need your UCLA Logon ID and password. If you do not have one, go to http://accounts.iam.ucla.edu/ and get one now.
2. Once in the Grid Identity Manager, you will be asked to select a faculty sponsor for your new cluster account. Please select Collaboratory Workshops as your faculty sponsor. After completing the selection for faculty sponsor, you’ll be ask to create a propose screen name, and grid password. Please complete the require information as requested.
