Parallel Processing of Navy Specific Applications Using a Workstation Cluster

Abstract

In this thesis the benefits of parallel computing using a workstation cluster are explored for two typical Naval applications. The applications are examples of one off-line and one on-line program. The off-line program is a Navy program currently in use by the Naval Space Command in its satellite prediction model. The on-line program is a large grain data flow problem with critical throughput requirements and represents a hypothetical combat weapons system. Data and function decomposition techniques are used in both applications. Speedup and throughput are the performance metrics studied. The software employed was the Parallel Virtual Machine (PVM) by the Oak Ridge National Laboratory. PVM enables a network of heterogeneous workstations to appear as a parallel multicomputer to the user programs. PVM runs over the workstation operating system and provides the user with a set of library calls for message passing and process creation.
