Presentation Transcript

  1. Alternative Processor Panel • Robert Singleterry: NASA’s Space Radiation Problem and FPGA Experience • Wu Feng: Performance Evaluation of Biological Codes on Cell and GPGPU • Richard Walsh: Larrabee Microarchitecture and Programming Potential Overview • Andrew Jones: Data Parallel or General Purpose Support and their Environments • John Gustafson: Alternative Processors and What is Really Needed

  2. NASA’s Space Radiation Problem and our Experience with Alternative Processors Robert C. Singleterry Jr. NASA Langley Research Center HPC Users Forum Tucson, AZ (GO Wildcats) 10-September-2009

  3. What does Space Radiation Do

  4. Code Details Boundary Conditions Physics Data Geometry (most complex) Interpolation Ray-by-ray Monte Carlo Finite Elements/SN Transport Response Functions Dose ETC… Dose Equivalent LET Effective Dose % REID

  5. Transport Codes • Interpolation • Serial can be vectorized • Ray-by-ray • Coarse parallel by ray with each ray vectorized • Monte Carlo • Inherently parallel – should be anyway • Cluster and vector • Finite Elements/SN • Space/energy/angle decomposition for cluster • Originally SN was vectorized

  6. Viva and FPGA After this, NASA stop supporting this work at my level
