Abstract: Apparatus comprises a data memory to store lock data for each of a set of processing resources, the lock data representing lock status data and tag data indicating a resource type selected from a plurality of resource types; and a processing element to execute an atomic operation with respect to the lock data for a given processing resource, the atomic operation comprising at least: a detection of whether the given processing resource is of a required resource type; a detection from the lock status data whether the given processing resource is currently unlocked; and when the given processing resource is detected to be currently unlocked and of the required resource type, performance of a predetermined action with respect to one or both of the lock status data and the tag data.

Abstract: Methods, systems, and media for binary compatibility comprises: receiving, from a foreign application, a function call to at least one surrogate function, wherein the at least one surrogate function is contained in a surrogate library, and wherein the surrogate library corresponds to a foreign library associated with the foreign function call; identifying a domestic function corresponding to the surrogate function; setting a pointer identifying a block of memory that is local to a thread associated with the surrogate function to point to a first portion of memory associated with the domestic function; invoking the identified domestic function; storing values including one or more error codes returned from the invoked domestic function; setting the pointer to point to a second portion of memory associated with the foreign function call; copying the one or more error codes to the second portion of memory; and continuing to execute the foreign application
