ABSTRACT:
An apparatus for and method of enhancing reliability and performance within a cluster lock processing system having a relatively large number of commodity instruction processors which are managed by a highly scalable, off the shelf platform. Because the commodity processors have virtually no system viability features such as memory protection, failure recovery, etc., the cluster/lock processors assume the responsibility for providing these functions. The low cost of the commodity instruction processors makes the system almost linearly scalable. The cluster/locking, caching, and mass storage accessing functions are fully integrated into a single hardware platform which performs the role of the cluster/lock master. The validity operation throughput of the clustered systems manager is increased by aging out validity entries for each of the process owners via a background operation. This minimizes the number of exclusive locks that must be utilized while performing a validity operation.
