Foil 6 Achieving 1 PF vs Bodega Bay Applications

From Some Numerical Memory and MicroProcessor Projections for PetaFlops JNAC (PetaFlops) Presentation -- August 28,1996. by Peter Kogge Notre Dame
10 TB Primary Memory supports almost all apps whose run time is under 1 day + over half of those that run > 1 day.
For 2007 conventional machine, using 2004 technology and a mere 10 TB primary memory
  • Approx. 20,000 DRAM chips @ $10M chip cost
  • AT LEAST 160,000 of state of art microprocessors
  • Problem: 1 memory chip/8 uPs fails bandwidth test!!!
At $1,000 per uP (cache, cooling, ...), this is approx
  • $200M machine
  • 1M sq. cm. of silicon
