Multi-Core CPUs Advantages Optimized for execution of sequential program • Complex Pipelines to achieve max frequency • Out Of Order, Super Scalar to achieve max ILP • Branch Predictors, Speculative execution • Register Renaming • Large Caches optimized for low latency access Multi-Core enables parallel multi-tasks/threads • Improved user response • Background task such as OS chores, virus scan, etc 36
Multi-Core CPUs Disadvantage Fine grain sharing of work between cores/caches • OS Overhead – spawn, communication, fork • Finding large number of task to Multi-tasktask is hard Embarrassing parallel apps • Limited Speed up (ALU & Bandwidth) • Limited Power/Flop advantage 37
