✦ Synopsis

In this paper, we present performance results from several parallel benchmarks and applications on two large Linux clusters at Sandia National Laboratories. We compare the results on the Linux clusters to performance obtained on a traditional distributed-memory massively parallel processing machine, the Intel TeraFLOPS. We discuss the characteristics of these machines that influence the performance results and identify the key components of the system that are important to allow for scalability of commodity-based PC clusters to hundreds and possibly thousands of processors.

## Abstract Rapid growth of computer network sizes and uses necessitate analysis of network application middleware in terms of its scalability as well as performance. In this paper we analyze a distributed network management middleware based on agents that can be dispatched to locations where they
