The ETS Supercomputing unit helps UCSB academic community members access and use the High Performance Computing (HPC) resources available from the national supercomputing centers: SDSC (San Diego Supercomputer Center) and XSEDE (Extreme Science and Engineering Discovery Environment).

SDSC resources are available through TSCC (Triton Shared Computing Cluster) to University of California researchers and affiliates. UCSB purchases an annual block of computing time that is allocated to individuals, research groups and for use in teaching. This resource is ideal for classes and novice users, or researchers who want to quickly get started on projects with preliminary calculations, due to the short wait times in obtaining access to the computing facilities. For more information, see the TSCC resources page.

The second program through which UCSB offers supercomputing facilities, XSEDE, is an advanced collection of computing resources and services funded by NSF (National Science Foundation). XSEDE is a network of several institutions across the country offering allocations on their machines. As a member of XSEDE's Campus Champions program, UCSB has an annual allocation totaling about 250,000 hours on different supercomputers and direct access to XSEDE's staff. In addition, ETS's supercomputing services also provide support to UCSB research groups writing individual grants for larger XSEDE allocations. For more information, see the XSEDE resources page.

SDSC also offers a new program HPC@UC for Unversity of California researchers. With HPC@UC, researchers can get up to 1M hours from the Comet and Gordon clusters. The awarded hours will be available for a year and the users are then expected to apply for a research allocation within the XSEDE program. Applications a re reviewed on an ongoing basis anand applicants will be notified within 10 days of review decision. For more information and application forms, please visit HPC@UC

UCSB's Center for Scientific Computing (CSC) also provides a broad range of resources for campus researchers. The CSC sponsors classes, tutorials, and individual training in general Unix/Linux, compiling, and optimization of code. A quick introduction to CSC resources can be found here.  A summary of UCSB's supercomputing resources is presented each year in a seminar, whose slides can be accessed here.
