SUG meeting continues growth

Columbus, Ohio (Dec 4, 2015) — 

Attendees at the semi-annual Statewide Users Group were immersed in a melting pot of eye-opening scientific research projects Thursday at the Ohio Supercomputer Center.

Research on topics such as virtual welding simulation, evolutionary modeling and water absorption – just to name a few – were on full display during the Flash Talk and Poster competitions of the SUG meeting.

Attendees to the Dec. 3 SUG meeting discuss research during the Poster competition.

SUG is a volunteer group comprised of the scientists and engineers who provide OSC’s executive director with program and policy advice and direction “to ensure a productive environment for research.” SUG was instituted in 1986, a year prior to the creation of OSC, to advise administrators and policy makers on their planning and acquisition activities for the Center.

“This is the third one we’ve had of this format,” said Brian Guilfoos, HPC client services manager at OSC. “This format has reinvigorated SUG and the next challenge for us is to continue that growth.

“I’m very happy with the turnout we’ve had and the exceptional number of people from around the state of Ohio coming out to show what they’re doing the services we provide.”

This meeting featured two Flash Talk sessions prior to the Poster session. A break between the Flash Talk sessions featured two keynote speakers.

Dr. Daniel Lacks, professor of Chemical Engineering at Case Western Reserve University, delivered a presentation titled “Solvophobicity” in which he discussed what makes a surfactant effective when the solvent is not just water. Suzy Tichenor, director of the Industrial Partnerships Program at Oak Ridge National Laboratory, followed with a presentation titled “Oak Ridge Leadership Computing Facility and Industry: Partnering for Success.”

Chris Ehemann of The Ohio State University claimed first place in the Poster competition followed by runner-up Connor Barber, also of the Ohio State University. Aaron Wilson, from Ohio State, won the flash talk portion with Ryan Ley, from Miami University, taking second place. Winners were awarded 5,000 resource units of time on OSC supercomputer systems, and their work will be featured in the Center’s annual research report. Second-place finishers got 2,500 units of supercomputer time.

Both winners said they were “surprised” to be awarded the top prize.

“There were a lot of good presentations today,” Wilson said. “This is the first one I’ve been to and there was a wide range of topics; a lot of things I don’t know a lot about. So I was able to briefly get introduced to a lot of different things. It was a good event.”

Wilson’s flash talk was on “Improving the Regional Arctic System Reanalysis with High-Performance Computing.”

“What we’re attempting to do is create a regional reanalysis that’s really high resolution in space and time,” he said. “It’s a blend of model observations to get a cohesive picture through space and time of the climate of the (arctic) region, and so we can take a model for the past and team that up with the observations and be able to look back and find out whether the climate changed over time.”

Ehemann’s poster was titled “Atomistic modeling of Ti-Nb alloys.” His abstract red: “Titanium alloys containing refractory metals like niobium exhibit multiple martensitic phase transformations involving coordinated motion of tens of thousands of atoms. Such large systems cannot be practically modeled with atomic-scale quantum-mechanical methods. This challenge is met by developing a classical molecular dynamics potential that mimics quantum mechanics with an algorithm suitable for large systems. We have developed a Modified Embedded-Atom Method (MEAM) potential for the Ti-Nb system, fitted to first-principles data using a genetic algorithm. Accuracy of the MEAM potential is tested by predicting the measured elastic anisotropy and phase transformation dynamics.”

Ehemann said he was very happy with how the poster turned out, “This was the first time I had large-scale dynamics results to present so that was really the driving force behind doing the poster.”

Barber claimed runner-up with a poster titled, “Quantifying Ionic Aggregates during Mechanical Deformation of Ionomer Systems using Molecular Dynamics Simulations.” Meanwhile, Ley’s second-place flash talk was titled “Investigating the phase behavior of Lidocaine in 1-n-butyl-3-methylimidazolium based ionic liquids.”

The meeting also included an OSC Organizational Update, in which outgoing OSC and OARnet Executive Director Pankaj Shah – who was recently selected as president and CEO of the Lonestar Education and Research Network – discussed his time leading OSC along with the future.

“You’re in great hands with the leadership here,” he said. “Both organizations are on very firm ground. For a leader, there’s nothing better than to leave an organization in better shape than you found it. I’m very grateful to the administration and all of you.”

The next SUG meeting is scheduled for early June.
