Non-Uniform Memory Access - NUMA Vs. Cluster Computing

NUMA Vs. Cluster Computing

One can view NUMA as a very tightly coupled form of cluster computing. The addition of virtual memory paging to a cluster architecture can allow the implementation of NUMA entirely in software where no NUMA hardware exists. However, the inter-node latency of software-based NUMA remains several orders of magnitude greater than that of hardware-based NUMA.

Famous quotes containing the word cluster:

    “the green hells of the sea
    Where fallen skies and evil hues and eyeless creatures be;
    On them the sea-valves cluster and the grey sea-forests curl,
    Splashed with a splended sickness, the sickness of the pearl;”
    —Gilbert Keith Chesterton (1874–1936)
