Conventional performance environments are based on pro ling and event instrumentation. It becomes problematic as parallel systems scale to hundreds of nodes and beyond. A framework of developing an integrated performance modeling and prediction system, SCALability Analyzer (SCALA), is presented in this study. In contrast to existing performance tools, the program performance model generated by ...

The paper describes the configuration of a synchronization link sharing hardware components with the SAR instrument. Such a system is intended for the TanDEM-X mission. The resulting restrictions on the phase synchronization scheme, timing, and accuracy are investigated. The statistical properties of the phase compensation signal are used to derive a figure-of-merit for synchronization performa...

Distributed systems are available and provide vast compute and data resources to users. With the availability of multiple resources, one of the major issues to be addressed is site selection. Users have access to many resource sites from which to select for execution of applications. In this paper, we quantify the advantages of using performance prediction to select sites as compared to using l...

This paper is about the merging of two software applications that allows building decision makers to consider code compliance and to use performance simulation tools from the early, schematic phases of building design. By making the capabilities of a code compliance tool available at the early schematic phases of building design, the hope and expectation is that users will use this software to ...

The earlier concern was sparked by a paper by Mankiw and Weil (1989), in which the authors famously predicted that between 1987 and 2007, real house prices could fall by 3% per year. In fact, real house prices grew by an average of 31/2% per year from 1987 to 2004. Of course, the MankiwWeil prediction may yet come to pass; or it may have already occurred and simply been masked by the surge in d...
