Abstract: Apparatuses, methods and storage medium associated with spinlock are disclosed herein. In embodiments, an apparatus for computing may comprise a first and a second processor core to correspondingly execute a first and a second thread; a storage location to store a spinlock to facilitate exclusive access by the first or the second thread to a plurality of resources implicitly shared by the first and second threads; and spin logic to be executed by the second processor core to occupy the second processor core to suspend execution of the second thread to prevent the second thread from using any one of the implicitly shared resources, whenever the spinlock is set by the first thread for exclusive access to one or more of the implicitly shared resources. Other embodiments may be disclosed or claimed.

Abstract: 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.

Abstract: A method including requesting access to a resource governed by a spinlock; determining an allocation of the resource to a further requester; determining an expiration of a time limit for the spinlock, if the resource is allocated to the further requester; and initiating a fault recovery, if the time limit is expired.
