To maintain a dialogue with the external community on DOE high performance computing (HPC) research and development challenges as the DOE NNSA and Office of Science partnership moves beyond petascale to new exascale models of computing while addressing eight focus areas:

  • Applications
  • Solvers, algorithms, and libraries
  • Programming models
  • Hardware architecture
  • System software
  • Tools
  • I/O, networking, and storage
  • Visualization and data analysis
