Oak Ridge National Laboratory’s Jaguar supercomputer has completed the first phase of an upgrade that will keep it among the most powerful scientific computing systems in the world.
U.S. Energy Secretary Steven Chu recently made a quick visit to ORNL, where he got a briefing on advanced computer simulations of nuclear energy and even took a turn experiencing the 3D environment of a virtual reactor’s nuclear core.
ORNL is upgrading its Jaguar supercomputer to become Titan, a Cray XK6 that will be capable of 10 to 20 petaflops by early 2013. To prepare users for impending changes to the computer’s architecture, OLCF staff held a series of workshops January 23 through 27.
Researchers at ORNL are sharing computational resources and expertise to improve the detail and performance of a scientific application code that is the product of one of the world’s largest collaborations of climate researchers.
During Phase Five, the entire machine will be returned to users. The machine will consist of 200 cabinets running on …
Hai Ah Nam, a computational scientist a the OLCF, and Channa Palmer, ORNL university recruiter, led the SCUWP group through tours of ORNL’s historic Graphite Reactor, Spallation Neutron Source, OLCF, and the Everest Powerwall, a 30-foot screen for scientific visualizations.
Community development of the Lustre file system was named one of HPCwire.com’s most important trends in 2011. This came as no surprise to the computational science community at Oak Ridge National Laboratory (ORNL).
With Titan’s arrival, fundamental changes to computer architectures will challenge researchers from every scientific discipline. Members of the OLCF’s Application Performance Tools (APT) group understand the challenge. Their goal is to make the transition as smooth as possible.
Homa Karimabadi’s team, in close collaboration with William Daughton at Los Alamos National Laboratory, is currently using the OLCF’s Jaguar supercomputer to better understand the processes giving rise to space weather.
