  1. Chapter 2 Computer Clusters Lecture 2.2 Computer Cluster Architectures

  2. We will first discuss basic, small-scale PC or server clusters. • Then we will discuss how to construct large-scale clusters

  3. Basic Cluster Architecture

  4. Large Cluster Architecutres • In building large-scale clusters, cluster nodes are classified into two categories: compute nodes and service nodes. • Compute nodes appear in larger quantities mainly used for largescale searching or parallel floating-point computations. • Service nodes could be built with different processors mainly used to handle I/O, file access, and system monitoring. • For MPP clusters, the compute nodes dominate in system cost, because we may have 1,000 times more compute nodes than service nodes in a single large clustered system.

  5. MPP Cluster Compute node architecture • Homegeneous design • Hybrid node design

  6. Example MPP Cluster Architecture – IBM Blue Gene/L System

  7. Hardware, Software, and Middleware Support for Large Scale Clusters

  8. Chapter 2 Computer Clusters Lecture 2.3 Cluster System Interconnects

  9. High-Bandwidth Interconnect Technologies • Compare four interconnect technologies

  10. Interconnect Example: Google Search Engine Cluster

  11. InfiniBand Architecture
