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