Chapter 2 Computer Clusters

Lecture 2.2 Computer Cluster Architectures


Chapter 2 computer clusters

  • We will first discuss basic, small-scale PC or server clusters.

  • Then we will discuss how to construct large-scale clusters


Basic cluster architecture

Basic Cluster Architecture

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.


Chapter 2 computer clusters

  • MPP Cluster Compute node architecture

    • Homegeneous design

    • Hybrid node design


Chapter 2 computer clusters

  • Example MPP Cluster Architecture – IBM Blue Gene/L System
