  1. Strategies for preparing for PetaScale computing Group II (Baldridge)

  2. Consider a 20 year outlook • 2007 - CFP • 2011 - PetaFlop machine delivered • 2016 - PhDs • 2016 - first pass for production applications • 2021 - optimized production applications • 2026 - end of 20 years; exaflops?

  3. Reaching for PetaFlops Significant time investment for each 10-fold increase in parallelism Some apps are “Peta Ready” today Which will be ready tomorrow? We may not know which ones they are Peta Scale Flagship app Covers of science 100 TF Tera Scale (2006)

  4. Scope Focused vs. large scale efforts Different kinds of goals Level of funding and selection criteria Team User base Appropriateness for resources Scientific Merit and impact Significance Risk FocusedLarge scale

  5. Strategies for longer term preparation for potentially new PetaScale apps • Training programs, workshops, summer school - to create efficient codes. • Funds to be identified for parallel biological application development • Run time systems • Libraries • Biological Petaflop Computing Initiative, on the model of NMI • Specialized programs to capture the specific biology subfields for development

  6. Classification • Biological applications are difficult to classify • Different from classic PDEs • But inroads should be made to classification to enable communication and exchange of ideas
