AFFINITY GROUP ACCESS TO GLOBAL DATA

摘要

A method, system, and computer readable medium to share data on a global basis within a symmetric multiprocessor (SMP) computer system are disclosed. The method may include grouping a plurality of processor cores into a plurality of affinity groups. The method may include creating hints about the global data in the plurality of group data structures. Each group data structure may correspond to an affinity group. The method may read a first group data structure by a thread executing on a processor core associated with a first affinity group.

1. A method of managing data in a symmetric multiprocessor computer, comprising:
grouping a plurality of processor cores into a plurality of affinity groups; creating a global data hint from a global data structure in a plurality of group data structures in a memory, each group data structure corresponding to an affinity group of the plurality of affinity groups; and reading a first of the plurality of group data structures corresponding to a first of the affinity groups by a first thread executing on a first processor core associated with the first of the affinity groups.
