STRUCTURE AND METHOD FOR MANAGING WORKSHARES IN A PARALLEL REGION

摘要

A data processing system is adapted to execute at least one workshare construct in a parallel region. The data processing system uses at least one thread for executing a corresponding subsection of the workshare construct and provides control blocks for managi ng corresponding workshare constructs in the parallel region. A method of managing the contro l blocks comprises: adding an array of control blocks to a control block queue; assigning control blocks in the initialized array to corresponding workshare constructs in the parall el region until a barrier is reached; and waiting at the barrier for all threads in the parallel regio n to complete their corresponding subsections and then resetting the control block to the beginning of the control block queue. Also provided are a computer program product and a data processing system for implementing the method.
