Abstract
A method and system for scheduling the execution of a plurality of threads in a computer system to control the concurrency level. Operating system data structures, called "queue objects," control the number of threads that are concurrently active processing incoming requests to an application program, a server or other processor of requests. The queue objects keep track of how many threads are currently active, and ensure that the number of active threads is at or near a predetermined target level of concurrency. By ensuring that new threads are not added to the pool of active threads if the system is operating at or above the target level of concurrency, the queue objects minimize the number of superfluous context switches that the operating system must perform and thus increases system efficiency and throughput.
