    Application benchmark results for Big Red, an IBM e1350 BladeCenter Cluster
    (2009) Stewart, Craig A.; Link, Matthew R.; McCaulay, D. Scott; Rodgers, Greg; Turner, George; Hancock, David Y.; Wang, Peng; Saied, Faisal; Pierce, Marlon; Aiken, Ross; Mueller, Matthias S.; Jurenz, Matthias; Lieber, Matthias; Tillotson, Jenett; Plale, Beth A.
    The purpose of this report is to present the results of benchmark tests with Big Red, an IBM e1350 BladeCenter Cluster. This report is particularly focused on providing details of system architecture and test run results in detail to allow for analysis in other reports and comparison with other systems, rather than presenting such analysis here.

    Technical Report: Distributed Parallel Computing Using Windows Desktop Systems
    (2003) Hart, David; Grover, Douglas; Liggett, Matt; Repasky, Richard; Shields, Corey; Simms, Stephen; Sweeny, Adam; Wang, Peng
    Like many large institutions, Indiana University has thousands of desktop computers devoted primarily to running office productivity applications on the Windows operating system, tasks which are necessary but that do not use the computers’ full capacity. This is a resource worth pursuing. However, the individual desktop systems do not offer enough processing power for a long enough period of time to complete large scientific computing applications. Some form of distributed, parallel programming is required, to make them worth the chase. They must be instantly available to their primary users, so they are available only intermittently. This has been a serious stumbling block: currently available communications libraries for distributed computing do not support such a dynamic communications world well. This paper introduces Simple Message Broker Library (SMBL), which provides the flexibility needed to take advantage of such ephemeral resources.

    Three-Dimensional Paleohydrologic Simulation using Parallel geofe on the Teragrid Resources
    (2007) Wang, Peng; Cohen, Denis; Person, Mark A.; Gopu, Arvind; Gable, Carl W.
    Abstract—Parallel geofe, a parallel, three-dimensional finite element paleohydrologic modeling program, was developed based on the serial code, with the aim to simulate ground water flow on the Atlantic continental shelf in New England within the past two million years, and help to explain the large amount of unconventional freshwater plumes within offshore aquifer systems in the above area. We used ParMetis for mesh partitioning and Aztec to solve the sparse linear system for the modeled groundwater flow, heat transfer and solute transport processes. The resulting program demonstrates good scalability on the Teragrid systems.
