SYSTEM AND METHOD FOR IMPROVING RUN-TIME PERFORMANCE OF APPLICATIONS WITH MULTITHREADED AND SINGLE THREADED ROUTINES

摘要

[OOO42]A system and method for improving run-time performance of applications with multithreaded and single threaded routines that are linked with libpthreads library is disclosed. In one embodiment, a method for running a mixed ST/MT application program linked with libpthreads library including creating an interceptor library containing pthread application programming interface (pthread_API) call interceptors and loading the interceptor library into the mixed ST/MT application program, and running the mixed ST/MT application program by using light weight (L W) and heavy weight (HW) synchronization routines based on determining switchovers between ST and MT program modes, respectively, during run-time using the interceptor library.
