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 managing corresponding workshare constructs in the parallel region. A method of managing the control 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 parallel region until a barrier is reached; and waiting at the barrier for all threads in the parallel region 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.
