  3. ITRS 2008 Roadmap • <10 nm,100s of procs on chip, multi-TB flash chips, etc • ITRS = International Technology Roadmap for Semiconductors Everything’s fine! http://www.itrs.net/ ? Gregory F. Pfister - CASC Anniversary

  4. Moore’s Law Will End,with No Economical Replacement • Computing ⇒ cheaper, not faster (per proc) • Democratization of some HPC • Traditional full-function PC will have integrated high-end graphics • At least TFLOPS (SP) on your lap • (for some value of “lap”) • Cellphone/laptop; or Yotta-cloud/fog/vapor • Nothing in between, as far as you can tell • Charged not by rack or proc, but by KWH • And possibly bandwidth. Gregory F. Pfister - CASC Anniversary

  5. Parallelism • There will be no savior language or architecture. • But data will be gigantic • “embarrassing” or “trivial” parallelism • Uninteresting, but practical • Parallel for power reduction: Pwr  F2 • more procs, constant time ⇒ lower power Gregory F. Pfister - CASC Anniversary
