Just six months after coming online, Comet, the new petascale supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California, San Diego, is already blazing new paths of discovery, thanks in part to its role as a primary resource for an assortment of science gateways that provide scientists across many research domains with easy access to its computing power. Simply described, science gateways provide web browser access to applications and data used by specific research communities. Gateways make it possible to run the available applications on supercomputers such as Comet, so results come quickly, even with large data sets. Browser access offered by gateways allows researchers to focus on their scientific problem without having to learn the details of how supercomputers work and how to access and organize the data needed. For the most recent quarter ended September 30, there were 3,310 gateway users across all XSEDE systems, according to data compiled by Wilkins-Diehr. There were 64,377 research jobs run by all gateways across all systems during the quarter, and 86 percent of them were run on either Comet or SDSC’s data-intensive Gordon supercomputer.
