Time Synchronized Measurements in Cluster Computing Systems

August 1, 2000
Author(s)
Alan Mink, Robert J. Carpenter, M M. Courson
We describe hardware time synchronization instrumentation that we have developed which achieves time synchronization of better than one microsecond. The purpose of this instrumentation is for Quality of Service characterization of parallel and distributed

A Stall Metric to Track Communication Performance

February 15, 2000
Author(s)
Alan Mink, Wayne J. Salamon, Michael D. Indovina
Probing the communication protocol stack in Linux PC-based clusters to investigate erratic TCP/IP performance has led to a new metric, data stream stall, which is analogous to instruction stream stall in CPUs. Data stream stalling correlates well with

An Automated Benchmarking Toolset

January 1, 2000
Author(s)
M M. Courson, G J. Marcais, Alan Mink, B Traverse
The performance drive of parallel computing and platform upgrades or replacements are among the reasons frequent running of benchmark codes has become commonplace for application and platform evaluation and tuning. NIST is developing a prototype for an

Implementation of an Interactive Digital TV Java Environment

January 1, 2000
Author(s)
Robert D. Snelick, Wayne J. Salamon, Alan Mink
The emergence of interactive digital television (DTV) brings about a host of exciting opportunities for broadcasters, content providers, tool developers, and equipment manufacturers. Interactive DTV combines aspects of traditional television and the

Linux-Based Clusters at the National Institute of Standards and Technology

June 1, 1999
Author(s)
Wayne J. Salamon, Alan Mink
The Scalable Parallel Systems and Applications Group at the National Institute of Standards and Technology (NIST) has been experimenting with Linux-based clusters of computers. These clusters are used for both the running of computationally intensive

Performance Measurement of Remote ATM Clusters

April 1, 1999
Author(s)
C Martin, Alan Mink, Wayne J. Salamon, Michael D. Indovina, M M. Courson
We investigate the configuration and performance of remote commodity computing clusters. This is the dynamic pooling of separate clusters into a single large remote cluster via existing LANs or even the Internet. We discuss the configuration and setup of

Parallel Implementation of a Molecular Dynamics Simulation Program

December 13, 1998
Author(s)
Alan Mink, C A. Bailly
We have taken a NIST molecular dynamics simulation program (md3), which was configured as a single sequential process running on a CRAY C90 vector supercomputer, and parallelized it to run in a distributed memory message passing environment. Since

Performance Measurement Using Low Perturbation and High Precision Hardware Assists

December 3, 1998
Author(s)
Alan Mink, Wayne J. Salamon, J Hollingsworth, R Arunachalam
We present the design and implementation of MultiKron PCI, a hardware performance monitor that can be plugged into any computer with a free PCI bus slot. The monitor provides a series of high-resolution timers, and the ability to monitor the utilization of
