Abstract
Systems, devices, and techniques for processor synchronization are described. A described system includes sending, from first processors, release requests to an inclusion monitor, the release requests including an identifier tag; sending, from a second processor, an acquire request to the inclusion monitor circuitry, the acquire request including a weight value and the identifier tag; creating a content addressable memory (CAM) entry based on a receipt of at least one of the release or acquire requests; maintaining a count of the release requests that correspond to the identifier tag by using the entry's arrival counter; causing the first processors to stall if the entry's arrival counter does not satisfy a threshold criterion specified by the entry's weight value or if the acquire request has not been received; storing the acquire request's weight value as the entry's weight value; and releasing the first processors if the entry's arrival counter satisfies the criterion.
