Abstract

This paper presents measured communication and computational performance results on an ad-hoc computing network composed of several geographically distributed nodes. Communication speed was measured for three basic communication patterns commonly used in parallel and distributed applications: point-to-point, bidirectional ring, and all-to-all communication. For that purpose simple test programs were made, based on the MPI library. The parallel execution
time of two real-life computationally intensive parallel applications is also presented.
Results show that only the applications with low communication requirements could be beneficially executed on computing networks.
