  1. La microarchitecture est morte. Longue vie à la microarchitecture! ISCA 2010 Panel, St. Malo, France (Microarchitecture isdead.Long live microarchitecture!)

  2. HPCA 2007 Debate [IEEE Micro 11-12/2007] • Amdahl’s Law and the Multicore Era [Computer 7/2008] • Software F parallel & 1-F sequential • Base core 1 resource  1 performance • Enhanced core R resources  performance • N resources per chip  N/R symmetric cores

  3. Speedup for Symmetric Multicore Chips 99% 90% 100% Fraction Parallel: 16 Base Cores 14 7 16 256 Base Cores 80 27 256  Concentrate on Increasing Parallelism!

  4. Asymmetric Optimal Core Size for Symmetric Multicore Chips 99% 90% 100% Fraction Parallel: 16 Base Cores 1 2 1 1 41 118 256 Base Cores 1 3 28  Concentrate on Core Design!

  5. Trends in Core Microarchitecture Research Credit Dan Gibson; Blame Mark Hill, 6/2010 5

  6. La microarchitecture est morte. Longue vie à la microarchitecture! ISCA 2010 Panel, St. Malo, France (Microarchitecture isdead.Long live microarchitecture!)
