Abstract

A module capable of performing up to K synchronizing operations in a single request/response cycle, where K is smaller than N, the number of processors in a multiprocessor system, is described. The objective is to provide for parallel synchronization to the degree that it is expected to be useful, but not to the degree that supports fully parallel synchronization of all processors in a system, which is far more costly to implement.
