The Performance of Parallel Disk Write Methods for Linux Multiprocessor Nodes to a local disk on Linux-based multiprocessor nodes. Using synthetic benchmark programs written with MPI and Pthreads, we have acquired detailed performance data for different application characteristics of programs running on dual processor nodes. In general, our results show that programs that pe

Evaluating the Performance of MPI-2 Dynamic Communicators and One-Sided Communicationperformance using dynamically created communicators is comparable to the approach presented in MPI-1 using a static communicator for different MPI libraries. We than evaluate, whether the communication performance of one-sided communication on current machines, represents a benefit or a drawback to

Ring Algorithms on Heterogeneous Clusters with PVM: Performance Analysis and Modelingge interactions. The algorithms were originally developed for homogeneous parallel systems, where they yield a nearly linear speed-up. Two heterogeneous platforms are considered: a network of ALPHA Unix workstations and a network of Pentium PCs with Windows 2000. The parallel framework is PVM..Our a

An MPI Tool to Measure Application Sensitivity to Variation in Communication Parametershe impact of communication performance on parallel applications. Our tool is based on Myrinet (along with GM). We use an extension of the LogP model to allow greater flexibility in determining the parameter(s) to which parallel applications may be sensitive. We show that individual communication par

Measuring MPI Latency Variancet the common way of measuring latency hides valuable information about the transmission time characteristics. We introduce a simple benchmark to measure transmission time variance and report on the results from a variety of systems.
