Performance models for parallel applications under failures
… The overall goal of this research is to get good performance of parallel applications despite failures. This dissertation introduces two mathematical models to improve resilience of parallel applications on two different frameworks. The first one is a mathematical model to minimize job completion …

Interfacing VHDL performance models to algorithm partitioning tools
Performance modeling is widely used to efficiently and rapidly assess the ability of multiprocessor architectures to effectively execute a given algorithm. In a typical design environment, VHD L performance models of hardware components are interconnected to form structural models of the target …

Characterization of Cooled Turbine Efficiency for Off-Design Performance Models
<p>Gas turbine performance modeling is essential for predicting engine behavior across design and off-design conditions. Yet the treatment of cooling or service flows remains inconsistent, as these streams interact with the main flow in complex ways and their contribution to turbine work depends on …

Mission planning for coupled human-robot teams using adaptive human performance models
… to the dynamic and stochastic nature of human performance. Reliable prediction of human task execution is challenging, and even proven models are subject to time-varying characteristics (e.g. fatigue and distraction) as well as differences between individuals (e.g. experience and skill). The …

Energy and Performance Models Enabling Design Space Exploration using Domain Specific Languages
… the advent of exascale architectures maximizing performance while maintaining energy consumption within reasonable limits has become one of the most critical design constraints. This constraint is particularly significant in light of the power budget of 20 MWatts set by the U.S. Department of …

Development of performance models for co-operative information systems in an organisational context
… are carried out and their principal effect (or performance) may therefore be evaluated by determining to what extent they are being employed to perform these tasks. A significant feature of CIS use identified is the extent to which they may be designed to fulfil particular tasks, or by contrast, …

The Use of Expert Pilot Performance Models to Facilitate Cockpit Visual Scan Training
… same 7-segment task as in Experiment I. Tracking performance and scan data were analyzed. The results suggest that whereas PTT without mental model development training (bottom-up PTT) provided limited benefits to flight performance, top-down mental model building appears to rapidly foster …

Methodology for VHDL performance model construction and validation
… languages(HDLs) are frequently used to construct performance models to represent systems early in the design process. This research study has resulted in the development of a methodology to construct VHDL performance models which will help to significantly reduce the time from an initial …

NUMA Data-Access Bandwidth Characterization and Modeling
… can adversely affect program execution performance by inflicting additional data-access performance penalties when accessing non-local data. In many modern NUMA architectures, both memory and I/O controllers are distributed within a node and CPU cores are logically divided into “local” …
