  • Low overhead thread synchronization using hardware-accelerated bounded circular queues
    Patent number: 10002031
    Abstract: A first thread is placed into a blocked state by causing the thread to perform a blocking pop operation on a hardware-accelerated, single-entry queue. When a synchronization event completes, a second thread may release the first thread from the blocked state pushing a data value onto the hardware accelerated, single-entry queue. The push operation satisfies the blocking pop operation, and the first thread is released.

  • System, method, and computer program product for a two-phase queue
    Patent number: 9928104
    Abstract: A system, method, and computer program product are provided for accessing a queue. The method includes receiving a first request to reserve a data record entry in a queue, updating a queue state block based on the first request, and returning a response to the request. A second request is received to commit the data record entry and the queue state block is updated based on the second request.
