Abstract
Described herein is a system and method of performing flow control for multi-threaded access to contentious resource(s) (e.g., shared memory). A request to enter a critical section of code by a particular thread of a plurality of concurrent threads is received. A determination is made as to whether or not to allow the particular thread to enter the critical section of code based, at least in part, upon a CPU core associated with the particular thread, a state associated with the particular thread, and/or a processing rate in the critical session of code associated with the particular thread. When it is determined to allow the particular thread to enter the critical section of code, the particular thread is allowed to enter the critical section of code.
