Scale-free Architectures • SW techniques for reliable computation on meshes of unreliable HW nodes • High value “statistical workloads” running reliably on meshes of unreliable cores (nodes) • HW meshes whose performance scale smoothly with size -- over multiple orders of magnitude(1K nodes upward) • “Write once”, scale-agnostic application code • Excessive defect tolerance, smooth response to soft error. • Shortened HW design cycle, minimum form factor, faster yield ramps. Farm (300K nodes) Server (50K) Desktop (20K) UMPC (2K) Cell phone (1K) All platforms with the same short design cycle
