Design of Hierarchical Thread Pool Executor for DSM

This paper discusses the Design and Implementation of Hierarchical Thread Pool Executor (HTPE) using the non blocking queues. This work enhances the performances of the Distributed Shared Memory (DSM) Programming. Few Java based DSMs make use of the concurrent utilities of Java that support the thread pool executor with blocking queues (i.e. Jackal). The study of the new proposed algorithm is done in a simulated environment which demonstrates that if the non-blocking queues are used, their performance improve significantly. The Hierarchical Thread Pool Executor using the non blocking queue has been simulated on the cluster environment using MinHeap tree data structure.
