Title: The Innovations of Charles Simmons
Introduction
Charles Simmons is a notable inventor based in San Mateo, CA. He has made significant contributions to the field of computer systems, particularly in lock management systems. With a total of 8 patents to his name, Simmons has developed innovative solutions that enhance resource access and deadlock protection in distributed systems.
Latest Patents
Simmons' latest patents include a system for managing locks that provide permission to access resources in a computer system. This lock management system is designed to be distributed, ensuring that information about which locks have been granted for a resource is stored at both a master node and at the nodes where processes desire access. The master resource object located on the master node grants locks to shadow resource objects on the nodes where the processes are located. Each shadow resource object is responsible for granting locks on the resource to the processes on the same node. Additionally, the system includes a convert queue that maintains a list of convert requests made by shadow resource objects. This innovative approach allows for efficient management of lock state transitions and provides deadlock protection.
Another significant patent by Simmons focuses on deadlock detection based on information stored in distributed objects participating in a distributed lock management system. This system also ensures that information about granted locks is stored at both the master node and the nodes where processes are located. Each shadow lock holds lock information that is crucial for detecting deadlocks, which can be represented through bipartite directed graphs that include nodes for resources and transactions.
