A Performance And Productivity Study Using Mpi, Titanium, And Fortress, Amy Apon, Chris Bryan, Wesley Emeneker
A Performance And Productivity Study Using Mpi, Titanium, And Fortress, Amy Apon, Chris Bryan, Wesley Emeneker

The popularity of cluster computing has increased focus on usability, especially in the area of programmability. Languages and libraries that require explicit message passing have been the standard. New languages, designed for cluster computing, are coming to the forefront as a way to simplify parallel programming. Titanium and Fortress are examples of this new class of programming paradigms. This papers presents results from a productivity study of these two newcomers with MPI, the de- facto standard for parallel programming.
What A User Wants: Redesigning A Library's Web Site Based On A Card-Sort Analysis, Laura Pope Robbins, Lisa Esposito, Christ Kretz, Michael Aloi

Web site usability concerns anyone with a web site to maintain. Libraries, however, are often the biggest offenders in terms of usability. In our efforts to provide users with everything they need to do research, we often overwhelm them with sites that are confusing in structure, difficult to navigate, and weighed down with jargon. Dowling College Library recently completed a redesign of its web site based upon the concept of usability. For smaller libraries in particular, this can be a challenge. The web site is often maintained by one or two people and finding the time and resources to conduct …

A fundamental goal of cyberinfrastructure (CI) is the integration of computing hardware, software, and network technology, along with data, information management, and human resources to advance scholarship and research. Such integration creates opportunities for researchers, educators, and learners to share ideas, expertise, tools, and facilities in new and powerful ways that cannot be realized if each of these components is applied independently. Bridging the gap between the reality of CI today and its potential in the immediate future is critical to building a balanced CI ecosystem that can support future scholarship and research. This report summarizes the observations and recommendations …
An Application Of High Fidelity Ftds For Ab Initio Pilot Training: The Way Ahead, Nickolas D. Macchiarella, Tim Brady, Brandon S. Lyon

"Decreases in simulation costs and increases in aircraft training costs led to the need for further investigation into the application of simulation-based training. Researchers conducted an eighteen-month study using ab initio student pilots as participants. This study applied a Federal Aviation Administration (FAA) approved, Part 142, flight-training curriculum that included 60% flight training device (FTD) use. Researchers identified five causal factors that warranted further investigation. The causal factors identified were visual fidelity, procedural similarity, dynamic flight environment, difficulty of task, and visual scanning and response. These causal factors have the potential to affect transfer of training (ToT) from simulated flight …
Capacity Planning Of A Commodity Cluster In An Academic Environment: A Case Study, Linh B. Ngo, Amy W. Apon, Baochuan Lu, Hung Bui, Nathan Hamm, Larry Dowdy, Doug Hoffman, Denny Brewer
Capacity Planning Of A Commodity Cluster In An Academic Environment: A Case Study, Linh B. Ngo, Amy W. Apon, Baochuan Lu, Hung Bui, Nathan Hamm, Larry Dowdy, Doug Hoffman, Denny Brewer

In this paper, the design of a simulation model for evaluating two alternative supercomputer configurations in an academic environment is presented. The workload is analyzed and modeled, and its effect on the relative performance of both systems is studied. The Integrated Capacity Planning Environment (ICPE) toolkit, developed for commodity cluster capacity planning, is successfully applied to the target environment. The ICPE is a tool for workload modeling, simulation modeling, and what-if analysis. A new characterization strategy is applied to the workload to more accurately model commodity cluster work- loads. Through "what-if" analysis, the sensitivity of the baseline system performance to …
