The Microsystems Subgrid Physics project is intended to address gaps between developing high-performance modeling and simulation capabilities and microdomain specific physics. The initial effort has focused on incorporating electrostatic excitations, adhesive surface interactions, and scale dependent material and thermal properties into existing modeling capabilities. Developments related to ea...

In Microblog retrieval, a system’s ability to know when to ”shut up” and how many results to return for a given query can have huge impact on its performance [1]. In addition, since relevant but redundant tweets will be deemed as irrelevant, it is also important to detect whether a tweet contain novel information or not. Therefore, in this year’s Real-Time Summarization Track, we focus on estim...

Improved Feedback for Architectural Performance Prediction using Software Cartography Visualizations Klaus Krogmann (Universität Karlsruhe (TH), Germany), Christian M. Schweda (Technische Universität München, Germany), Sabine Buckl (Technische Universität München, Germany), Michael Kuperberg (Universität Karlsruhe, Germany), Anne Martens (Universität Karlsruhe (TH), Germany) and Florian Matthes...

While ensembles have been used for structured output learning, the literature lacks an extensive study of different strategies to construct ensembles in this context. In this work, we fill this gap by presenting a thorough empirical comparison of ensembles that predict the complete output structure at once, versus a combination of ensembles that each predicts a single component of the structure...

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...
