Two Designs for a Petaflops System
Commodity technology design:
125,000 nodes, each w/8-way SMP.
Clock rate = 1 GHz; each processor sustains 1 Gflop/s.
Multi-stage switched network.
If built today, cost $40 B and consume 1 TWatt.
Silicon alone would take 3 football fields
May be feasible and “affordable” by the year 2010
