Latest Patents

One of his latest patents is focused on a multi-thread synchronization primitive. This invention relates to efficiently handling the execution of multiple threads to perform various actions. In this embodiment, an application instantiates a queue and a synchronization primitive. The queue maintains a set of work items to be operated on by a thread pool maintained by a kernel. The synchronization primitive controls access to the queue by multiple threads, including those of the thread pool. A first thread of the application enqueues a work item in the queue and issues a system call to the kernel to request that a thread of the thread pool operate on the first work item. The dispatched thread is executable to acquire the synchronization primitive, dequeue the work item, and operate on it.

Another significant patent is the Turnstile API for runtime priority boosting. This invention provides a computer-implemented method that includes instantiating a synchronization primitive to control access to a resource. The method involves acquiring the synchronization primitive at a first thread, which has a first priority, and associating a turnstile with the synchronization primitive. If a second thread, with a higher priority, attempts to acquire the synchronization primitive while it is held by the first thread, the priority of the first thread is increased to match that of the second thread.
