Supercomputing Resources

By Burak Himmetoglu, UCSB Supercomputing Consultant

The Supercomputing unit in Enterprise Technology Services (ETS) offers the UCSB academic community access to various High Performance Computing (HPC) resources. These resources are available through local, regional and national centers, serving both educational and research interests. Maintenance of accounts, allocations of computing time, user support and research consultation is provided by the campus supercomputing consultant, Burak Himmetoglu, who has worked at ETS since July 2015.

Triton Shared Computing Cluster

In collaboration with San Diego Supercomputer Center (SDSC), computing time is available to UCSB's research community through the Triton Shared Computing Cluster (TSCC). ETS purchases an annual block of service units that is allocated to individuals, research groups and for use in teaching. TSCC is ideal for instructors and research groups who want quick access to computer time without the requirement of writing detailed allocation proposals. UCSB researchers can access the TSCC by contacting the supercomputing consultant at Further information on policies and access to the TSCC is available at

Extreme Science and Engineering Environment

The second program through which UCSB offers HPC resources is Extreme Science and Engineering Environment (XSEDE), a service organization funded by the National Science Foundation (NSF). Currently, XSEDE supports more than a dozen supercomputers, as well as high-end visualization and data analysis resources across the nation. As a member of XSEDE’s Campus Champions program, UCSB has an annual allocation of supercomputing resources and direct access to XSEDE staff. The supercomputing consultant manages allocations and access to XSEDE resources.

UCSB researchers can obtain trial allocations on any XSEDE resources ( by contacting the supercomputing consultant. The trial allocations are limited, and researchers are expected to request startup and research allocations for conducting their projects.

The startup allocations are easily obtained with a one-page request, and usually available within two weeks of submission. Startup allocations are designed for researchers to develop codes, test the performance of their applications, and get a head start on their projects. Users are then expected to apply for Research Allocations, which requires a detailed request be submitted to the XSEDE allocations committee. This committee accepts applications four times a year.

Additionally, Educational Allocations through XSEDE are available year-round and require a short allocation request. For more information, visit or speak with your campus supercomputing consultant.

Center for Scientific Computing

UCSB’s Center for Scientific Computing ( provides a broad range of resources available to UCSB researchers and collaborators. ETS, in collaboration with the Center for Scientific Computing, sponsors tutorials, workshops, individual training in Unix/Linux computing environments, compiling and optimization of codes, and technical support for computational research at UCSB.
