With a total of two patents to his name, Closson has showcased his expertise and ingenuity, particularly within multi-node computer systems and distributed memory architectures.

Latest Patents

One of his latest patents, titled "Lingering locks with fairness control for multi-node computer systems," tackles the complexities of processing requests for locking mechanisms in multiprocessor setups. The innovation ensures that while a lock can only be granted to one processor at a time, it maintains fairness across nodes by rotating lock availability after a set number of consecutive requests or a defined time period. This is achieved using a specialized data structure that manages lock requests, promoting efficiency and minimizing delays in system processing.

Another essential patent by Closson is "Disk block cache management for a distributed shared memory computer system." This invention introduces a structured buffer cache management system specifically designed for a non-uniform memory access (NUMA) machine. It optimally partitions metadata for disk blocks and manages operations based on the locality of the requested data block. By doing so, Closson enhances performance through localized processing, thereby improving overall system efficiency.
