Present at the conference were Ph.D. students Robert Searles and Eric Wright from CRPL, Alex Bryer, a close collaborator from the University of Delaware department of chemistry, and Dr.
Four students from CRPL@ UDEL Mauricio Ferrato (Ph.D. student), Eric Wright (Ph.D. student), Robert Searles (Ph.D student), Kyle Friedline (Undergraduate student BSCS) attended the 2018 Brookathon - Brookhaven National Laboratory GPU hackathon held at BNL on September 17–21, 2018 as one of the 2 mentors for four hackathon teams. They have also served as mentors in the Boulder, Oak Ridge National Laboratory (ORNL), Pawsey Supercomputing Center and NASA hackathons. What do they have to say?
CRPL’s PhD Students Eric Wright and Mauricio Ferrato have a poster titled “Estimating Molecular Dynamics Chemical Shift with GPUs” accepted for the SC18 conference in Dallas. The research project was started as an undergrad project under the Vertically Integrated Project (VIP) program and consisted of accelerating a chemical shift prediction application called PPM_One using the parallel programming model OpenACC. CRPL’s undergraduate student Thomas Huber was also involved in this project. The application originally existed as a serial application only and porting it to OpenACC allowed to test for both multicore and GPU acceleration.
On Tuesday, July 3, 2018, Robbie presented his work on ORNL’s Minisweep miniappliation at The Platform for Advanced Scientific Computing (PASC) Conference. Watch his presentation below by clicking on the image.
The Vertically Integrated Project (VIP) program is a multi-year research as well as credit-based program for undergraduate students. Four students, Eric, Mauricio, Thomas and Edwin of CIS/CPEG recently won the VIP Best Poster Award in a inter-regional competition held at UDEL. They took a chemical shift prediction application called PPM_One, and accelerated it on state-of-the-art GPUs using the directive-based programming standard OpenACC. Results showed that the a dataset of ~2 million atoms running sequential for over 10+ hours took only 2 minutes on NVIDIA V100 GPUs.
Over the past year, Prof. Chandrasekaran and Robert Searles have teamed up with researchers Wayne Joubert and Oscar Hernandez of Oak Ridge National Lab in an effort to accelerate a miniapp called Minisweep. Minisweep is representative of the main computational kernel of a production Sn radiation transport application called Denovo, which is used for nuclear reactor neutronics modeling. This code is instrumental for nuclear scientists because modeling neutron flow helps them avoid a nuclear meltdown, and it provides them with information that is essential in designing an effective shielding system around the reactor to protect workers from excessive radiation exposure.
Prof. Chandrasekaran gave an HPC featured talk at the yearly GPU Technology Conference (GTC), San Jose, CA, 2018 on Adapting Minisweep, a Proxy Application, on Heterogeneous Systems Using OpenACC Directives based on work done by her PhD student Robert Searles. This is work in collaboration with Dr. Oscar Hernandez and Dr. Wayne Joubert at the Oak Ridge National Laboratory (ORNL). The talk highlighted programming challenges and its corresponding solutions using OpenACC, for porting a wavefront based miniapplication for Denovo, which is a production code for nuclear reactor modeling.
