OSC helps researchers unveil most accurate map of the invisible universe

COLUMBUS, Ohio — The Ohio Supercomputer Center played a critical role in helping researchers reach a milestone mapping the growth of the universe from its infancy to present day.

The new results released Aug. 3 confirm the surprisingly simple but puzzling theory that the present universe is composed of only 4 percent ordinary matter, 26 percent mysterious dark matter, and the remaining 70 percent in the form of mysterious dark energy, which causes the accelerating expansion of the universe.

Ohio Supercomputer Center runs largest scale calculation ever

The Owens Cluster is the most powerful supercomputer in OSC history. 

The Ohio Supercomputer Center recently displayed the power of its new Owens Cluster by running the single-largest scale calculation in the Center’s history.

Scientel IT Corp used 16,800 cores of the Owens Cluster on May 24 to test database software optimized to run on supercomputer systems. The seamless run created 1.25 Terabytes of synthetic data.

Statewide Users Group conference highlights OSC resources, client research

Overview

Research using Ohio Supercomputer Center resources continues to break new ground, and OSC clients continue to gain more high performance computer power and a better experience.

Nearly 100 attendees gathered at the Ohio Technology Consortium building for the conference, which featured a keynote address from NVIDIA’s Jonathan Bentz, breakout sessions on a variety of topics and the ever-popular poster and flash talk competitions. Participants presented 24 posters and 10 flash talks with winners receiving 5,000 resource units of time on OSC systems while runners-up gained 2,500 resource units.

Education Innovation

As part of the AweSim program, TotalSim USA has developed a computational fluid dynamics (CFD) app that allows college students on Formula SAE (Society of Automotive Engineers) teams to perform aerodynamics simulations on the Ohio Supercomputer Center and get wind tunnel-like data for development of their race cars. The app itself meshes geometry, configures solver settings, generates output visualizations and organizes results so students from such teams at The Ohio State University, the Univesity of Akron and Indiana University-Purdue University Indianapolis can focus on designing and improving their Formula SAE cars without being forced to become CFD experts.

 

SUG meeting illustrates wealth of OSC-supported research

SUG

More than ever, academic and manufacturing researchers from across Ohio are turning to the high performance computing power offered by the Ohio Supercomputer Center (OSC). On Thursday, an abundance of that research was on display at OSC’s semi-annual Statewide Users Group (SUG) meeting.

Attendees shared and gained insight into topics ranging from auto safety and dark matter to gene flow and a myriad of chemistry-related topics. They also heard two keynote addresses, and the competition portion of the meeting featured 27 posters and 12 flash talks.

 

OSC part of NSF-funded consortium for advancing research computing practices

CLEMSON, S.C. (Sept. 30, 2016) – The National Science Foundation has awarded a consortium of 28 collaborating institutions, including the Ohio Supercomputer Center (OSC) and led by Clemson University, a $750,000 grant to fund a Research Coordination Network to set up a national forum for the exchange and dissemination of best practices, expertise and technologies to enable the advancement of campus-based research computing activities. 

Ohio Supercomputer Center launches OnDemand 3.0

Columbus, Ohio – The Ohio Supercomputer Center has launched OnDemand 3.0, a vastly upgraded version of its “one-stop shop” for access to its High Performance Computing services.

This latest version of OSC’s custom-built OnDemand web portal is the first to be based on Open OnDemand, an NSF-funded OSC project to develop an open-source web portal providing advanced web and graphical interfaces for HPC centers.

Bharat Bhushan, Ph.D., and Samuel Martin, a Ph.D. candidate and co-author on Bhushan’s recent study, have used OSC resources to research black skimmer birds and shark skin to understand drag reduction.

Bharat Bhushan, Ph.D., was on sabbatical at EPFL in Lausanne, Switzerland in 2005 when a transformation began.

When life-threatening weather events loom, forecasters warn citizens days, even weeks, beforehand so they can take action. It seems to work: We clear supermarket shelves, board up windows and even evacuate to higher ground ahead of the impending tempest to avoid danger.
