1. Cluster and Warehouse-Scale Computing Responsible for Internet Services Websites (google) Content services (Netflix) Gaming (World of Warcraft) “Clouds” are examples of Clusters

2. Cluster Anatomy Made up of multiple nodes  Computer Nodes  Application Specific Integrated Circuits (ASIC) Networked together  TCP/IP Shares Kernel or Tasking protocol  Apache Hadoop  MapReduce  Message Passing Interface

3. History of Clusters First cluster unknown (Late 1950 – Early 1960)  Consumer need  Network Topologies  Network Protocols (TCP/IP) First Commercial Clusters  Datapoint ARCnet (1977)  Digital Eqipment Corporation's VAXcluster (1984)

4. Commodity Computing Non standardized hardware Tasking Protocols First: ARPANET 4 nodes (1969) Parallel Virtual Machine (PVM) (1989) Most Powerful Clusters  Bitcoin (1,166,652 PFLOPS) (June 2014)
