Method for computing the degree of parallelism in a multi-user environment

摘要

A method and apparatus are provided for computing degrees of parallelism for parallel operations in a computer system. The degree of parallelism for a given parallel operation is computed based on a set of factors. The set of factors includes a target degree of parallelism that represents a desired total amount of parallelism in the computer system, a current workload and a requested degree of parallelism.
