ASC Participates in First-Ever Office of Science HPC Symposium
ASC researchers were prominently represented in the first High Performance Computer Science Week (HPCSW), organized by DOE’s Office of Science in collaboration with the Krell Institute, held March 30 to April 4 in Denver, CO. The first half of the week featured a meeting of all principal investigators of the Office of Advanced Scientific Computing Research (OASCR) Computer Science projects, and the second week offered a comprehensive overview of the state of the art in HPC through one keynote, four panels, seven workshops, and two tutorials.
Researchers from the tri-lab community (LLNL, LANL, and SNL) represented a wide range of DOE/OASCR-funded projects from systems research to visualization. The program also featured an invited presentation by LLNL's Nathan Barton on the Cooperative Parallelism (COOP) framework developed at LLNL to support large-scale coupled simulations.
The HPCSW program in the second half of the week contained an international workshop on interoperable tool infrastructures with participation from several research groups in the U.S. and Germany. Organized by Martin Schulz and Bronis de Supinski (LLNL), David Montoya (LANL), and Jim Galarowicz (Krell Institute), it provided the stage for extensive discussions on how to build reusable software components that can be used across individual tools and how to scale them to future machines.
The Open|SpeedShop team represented by Schulz, Montoya, and Galarowicz presented a tutorial focusing on performance analysis using the ASC toolset Open|SpeedShop, and de Supinski gave an invited presentation at a workshop on Autotuning organized by Mary Hall (Information Sciences Institute/USC).
Bronis de Supinski (LLNL) presents his invited talk on Autotuning.
