Accelerating ParaView on Crusher with VTK-m

  • Science Problem
    • DOE has a set of well-established tools to perform visualization for scientific discovery.
    • The software for these tools, dating back to the 1990’s, is designed for CPU processing.
    • New software is required to utilize the GPU acceleration needed for interactive visualization.
  • Technical Solution
    • The VTK-m visualization library is redesigning visualization algorithms for efficient execution on GPU devices.
    • VTK-m is being integrated into tools such as ParaView.
  • Science Impact
    • ParaView was demonstrated running on Crusher (Frontier early-access hardware) GPUs.
    • VTK-m is integrated to replace existing functionality with no effort on the users’ part.
    • Visualization tools continue to support science discovery.
