COMMON RESOURCE UPDATING APPARATUS AND COMMON RESOURCE UPDATING METHOD

摘要

A common resource to be updated is logically divided among the respective threads, and update processing is performed in parallel among a plurality of cores. The common resource updating apparatus comprises a processor which controls an execution of a program configured from a plurality of threads, and updates a common resource including a plurality of areas associated with the plurality of threads, wherein the processor causes at least one thread among the plurality of threads to be an update thread which updates an area of the common resource associated with the thread, and causes a thread that is different from the update thread to be a reference thread which sends an update request to the update thread upon updating the common resource, and directly refers to the common resource upon referring to the common resource.
