Accelerating Chemical Shift Prediction of Protein Structures using GPUs

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.

Accelerating Nuclear Reactor Modeling Code on 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.

Accepted/Invited Talks

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.

Robbie, Kyle, Sanhu, and Jose Travel to Brookhaven National Laboratory for GPU Hackathon

On June 5-9, 2017, CRPL’s Robert Searles, Kyle Friedline, Sanhu Li, and José Monsalve Díaz traveled to Brookhaven National Laboratory (BNL) to participate in the GPU Hackathon hosted there. BNL hosted this event in conjunction with NVIDIA, The Portland Group (PGI), and Oak Ridge National Laboratory (ORNL). Robbie and Kyle acted as mentors for their teams, providing insight using their extensive GPU programming experience. Robbie served as the mentor for Team Uduh: a combination of members from University of Delaware and University of Houston.
