The exemplary embodiments describe systems and methods for utilizing a semaphore with timeout and lock-free path for message passing architectures. One embodiment is related to a method comprising receiving a request from a client to access an object, the object including a plurality of resources, placing the request in a lock-free pend queue of a semaphore, manipulating a count of the semaphore based on an availability of at least one of the plurality of resources, and determining whether the client can use a fast path to the object.
