SYMMETRY MANAGEMENT IN MULTIPROCESSOR SYSTEMS

摘要

A set of processors in a symmetric multiprocessor (SMP) system are deconfigured following a first failed processor to return the SMP system to a symmetric state. One or more deconfiguration options are identified, and a respective cost is calculated for each deconfiguration option. A deconfiguration option is selected and applied to the SMP system based on the respective costs of the one or more identified deconfiguration options.

1. A method comprising:
identifying a first failed processor, wherein the first failed processor is a component of a symmetric multiprocessor system, wherein the first failed processor is associated with a set of horizontally corresponding processors and a set of vertically corresponding processors in the symmetric multiprocessor system; calculating a horizontal cost of deconfiguring the first failed processor and the set of horizontally corresponding processors; calculating a vertical cost of deconfiguring the first failed processor and the set of vertically corresponding processors; determining a first deconfiguration based on the horizontal cost and the vertical cost; and deconfiguring a set of processors associated with the first deconfiguration.
