1. FAWN:
A Fast Array of Wimpy Nodes
Presented by:
Clint Sbisa & Irene Haque
2. Motivation
Large-scale data-intensive applications
Facebook, LinkedIn, Dynamo
CPU-I/O Gap
storage, network and memory bottlenecks
low CPU utilization
CPU Power
slower CPUs execute more queries per second per Watt
1 billion vs. 100 million instructions per Joule
inefficient energy saving techniques
Memory Power
