Scalable Multiprocessors
 
 
- Must scale the local memory bandwidth linearly.
- Must scale the global interprocessor communication bandwidth.
- Scaling memory bandwidth cost-effectively requires separate, distributed memories.
- Cost-effectiveness also requires best price-performance in individual processors.
- What we get:
- 
- Compelling Price/Performance
-  Tremendous scalability
-  Tolerable entry price
-  Tackle intractable problems
