  1. Panel: System Architecture: Near, Medium and Long-term Scalable ArchitecturesCSRI Workshop: When MPI-only is not enough Douglas Doerfler Sandia National Labs Scalable Architectures Group dwdoerf@sandia.gov

  2. System Architecture Issues • Power - 2nd order - Medium/Long • Engineering Issue, not programming model • Low hanging fruit: Line to Machine • New Architectures - 2nd order - Medium/Long • Higher radix router trends • Scalability - 2nd order - Medium/Long • Application: Don’t do something w/o a scalable solution • Programming Model - 2nd order - Long • Will the model ever drive the architecture? • Resiliency - 1st order - Near/Medium • All the above really doesn’t matter if your job only lasts 10 minutes
