Foil 42 Supercomputer Architectures in Years 2005-2010 -- I

From General NPAC Foils-B starting June97(PowerPoint) Beijing and Chang Sha China -- 28 Dec 97 to 5 Jan 98. by Geoffrey C. Fox
Conventional (Distributed Shared Memory) Silcon
  • Clock Speed 1GHz
  • 4 eight way parallel Complex RISC nodes per chip
  • 4000 Processing chips gives over 100 tera(fl)ops
  • 8000 2 Gigabyte DRAM gives 16 Terabytes Memory
Note Memory per Flop is much less than one to one
Natural scaling says time steps decrease at same rate as spatial intervals and so memory needed goes like (FLOPS in Gigaflops)**.75
  • If One Gigaflop requires One Gigabyte of memory (Or is it one Teraflop that needs one Terabyte?)
