STRUCTURE AND METHOD FOR MANAGING WORKSHARES IN A PARALLEL REGION

摘要

A data processing system is adapted to execute at least one workshareconstruct in a parallelregion. The data processing system uses at least one thread for executing acorrespondingsubsection of the workshare construct and provides control blocks for managingcorrespondingworkshare constructs in the parallel region. A method of managing the controlblockscomprises: adding an array of control blocks to a control block queue;assigning control blocksin the initialized array to corresponding workshare constructs in the parallelregion until a barrieris reached; and waiting at the barrier for all threads in the parallel regionto complete theircorresponding subsections and then resetting the control block to thebeginning of the controlblock queue. Also provided are a computer program product and a dataprocessing system forimplementing the method.
