U Arkansas Acquires SDSC's Trestles Supercomputer

The University of Arkansas is the proud new owner of a supercomputer featuring 256 servers, 16.4 terabytes of memory, a processing speed of 79 teraFLOPs and 8,192 processing cores.

The supercomputer, named Trestles, is being moved from the San Diego Supercomputer Center (SDSC) at the University of California, San Diego to the Arkansas High Performance Computing (HPC) Center. The University of Arkansas' existing supercomputer, named Razor, has a processing speed of 77 teraFLOPs and 4,328 processing cores. The addition of Trestles will more than double the Arkansas HPC Center's computational capacity and allow it to run three times as many jobs for researchers.

SDSC and UC San Diego originally deployed Trestles in 2010 with a $2.8 million grant from the National Science Foundation (NSF), and the supercomputer was "recognized as the leading science gateway platform in the NSF's eXtreme Digital (XD) Network, a collaborative set of compute and storage resources in the United States that scientists can use for advanced computational and data-enabled research," according to information from the University of Arkansas and SDSC.

Jeff Pummill is one of the interim co-directors of the Arkansas HPC Center. Last year, through his connections with the NSF's XSEDE (eXtreme Science and Engineering Discovery Environment) program, Pummill learned that SDSC planned to replace Trestles with its new petascale Comet supercomputer and the organizations made arrangements to transfer ownership of Trestles to Arkansas.

In preparation for the installation of Trestles at the Arkansas HPC Center, the University of Arkansas will decommission the Star of Arkansas supercomputer, which was activated in 2007 and was once the most powerful computer in the state.
