Functional units provide the backbone of any spatial accelerator by providing the computing resources. The desire for having rich and expensive functional units is in tension with producing a regular and energy-efficient computing fabric. This paper explores the design trade-off between complex, universal functional units and simpler, limited functional units. We show that a modest amount of specialization reduces the area-delay-energy product of an optimized architecture to 0.86× a baseline architecture. Furthermore, we provide a design guideline that allows an architect to customize the contents of the computing fabric just by examining the profile of benchmarks within the application domains.

Since almost one decade HCI pattern languages are one popular form of design knowledge representations which can be used to facilitate the exchange of best practices, knowledge and design experience between the interdisciplinary team members and allow the formalization of different user interface aspects. Since patterns usually describe the rational in which context they should be applied (when), why a certain pattern should be used in a specific use context (why) and how to implement the solution part (how) they are suitable to describe different user interface aspects in a constructive way. But despite intense research activities in the last years, HCI pattern languages still lack in a lingua franca, a common language for the standardized description and organization of the pattern. This makes it difficult to design suitable tools that support the developers in applying HCI patterns in model-based user interface development (MBUID) processes. To enable the constructive use of HCI patterns in the model-based development process the informal textual, or graphical notation of HCI patterns has to be overcome. Besides that, evaluating the effectiveness of a pattern, i.e. when is a pattern a "good" pattern is an important issue that has to be tackled to fully benefit from HCI patterns and to improve their applicability in future design processes.

As supercomputers grow ever larger, so too do application run times and data requirements. The operational patterns of modern parallel I/O systems are far too complex to allow for a direct analysis of their trace logs...

Driving and visual perception are tightly linked. Every moment, a multitude of visual stimuli compete for the driver's limited attentional resources. Despite modern safety measures, traffic accidents still remain a major source of fatalities. A large part of these casualties occur in accidents for which driver distraction was cited as the main cause [National Highway Traffic Safety Administration September 2010]. We propose to help drivers by building an augmented vision system that can guide eye movements towards regions which may constitute a source of danger. In a first study, we have already shown that largely unobtrusive gaze guidance techniques used in a driving simulator help drivers better distribute their attentional resources and drive more safely [Pomarjanschi et al. 2011]. Current experiments investigate the efficiency of more general cues, that only signal the direction in which a critical event might occur. Results of these experiments will be reported at the conference.
