  1. Advanced Computing Breakout Session THURSDAY - JUNE 22, 2006 (08:30 - 10:00) Todd Hutchinson - WSIChris Harrop – NOAA/GSDWei Huang – NCAR/SCDJoe Klemp - NCAR/MMMGerardo Cisneros - SGI

  2. Pre-Requisites for Petascale Computing • “Computation” is the easy part • How do we handle: • I/O Performance • parallel netCDF, MPI-IO, PHDF, … • Long-term storage • Analysis • Visualization • Feature extraction

  3. Pre-Requisites for Petascale Computing • Operations • Run the same thing over and over with different data • Research • NOT a waterfall • Iterative process • Analysis leads to new requirements • Storage vs. re-run

  4. Other Issues • Dynamic Load Balancing • Adaptive Timestep • How do I get my code into WRF? • Integration support • Web page • Process • Developers meeting • Testing • Action for MMM: publish process more visibly

  5. Other Issues • Dynamic Load Balancing • Adaptive Timestep • How do I get my code into WRF? • Integration support • Web page • Process • Developers meeting • Testing • Action for MMM: publish process more visibly

  6. Other Issues • Ease of use • Ease of development • Build rework • SI replacement • Registry generation • GIS, CF • Coupling • Grand Challenges vs. everything else?
