Systematic derivation of time and power models for linear algebra kernels on multicore architectures
(Elsevier, 2015-09)
The power wall asks for a holistic effort from the high performance and scientific communities to develop power-aware tools and applications which ultimately drive the design of energy-efficient hardware. Toward this goal, ...
Sketch Retrieval based on Qualitative Shape Similarity Matching: Towards a Tool for Teaching Geometry to Children
(IOS Press, 2015)
An approach for a query-by-sketch system on qualitative
shape information for image retrieval in databases is proposed
and evaluated. The use of qualitative methods for
shape description allows the gathering of semantic ...
Learning the visual-oculomotor transformation: Effects on saccade control and space representation
(Elsevier, 2015-09)
Active eye movements can be exploited to build a visuomotor representation of the surrounding environment. Maintaining and improving such representation requires to update the internal model involved in the generation of ...
Fast video transcoding from HEVC to VP9
(Institute of Electrical and Electronics Engineers, 2015-10)
HEVC and VP9 are the current state-of-the-art in video compression, since their bit-streams were recently finalized in January and May 2013, respectively. These codecs are the generational successors of the currently most ...
Toward the Robot Butler: the HUMABOT Challenge
(Institute of Electrical and Electronics Engineers (IEEE), 2015-06)
Presents information on the HUMABOT Challenge, the official robot competition for the 2014 IEEE Robotics and Automation Society (RAS) International Conference on Humanoid Robots (Humanoids 2014) that was held during the ...
Reducing the cost of power monitoring with DC wattmeters
(Springer Berlin Heidelberg, 2015-05)
The use of internal DC wattmeters, connected to the ATX lines that distribute power from the supply unit to the computer components, is a luring method to profile power in server configurations due to the accurate and ...
Are our dense linear algebra libraries energy-friendly?. Time–power–energy trade-offs in BLAS and LAPACK
(Springer Berlin Heidelberg, 2015-05)
In this paper we conduct a detailed analysis of the sources of power dissipation and energy consumption during the execution of current dense linear algebra kernels on multicore processors, binding these two metrics together ...
An analytical methodology to derive power models based on hardware and software metrics
(Springer Berlin Heidelberg, 2015-09)
The use of models to predict the power con-
sumption of a system is an appealing alternative to
wattmeters since they avoid hardware costs and are
easy to deploy. In this paper, we present a systematic
...
RF-Based Location Using Interpolation Functions to Reduce Fingerprint Mapping
(MDPI, 2015-10)
Indoor RF-based localization using fingerprint mapping requires an initial training step, which represents a time consuming process. This location methodology needs a database conformed with RSSI (Radio Signal Strength ...
Evaluating the performance and energy efficiency of the COSMO-ART model system
(Springer Berlin Heidelberg, 2015-05)
In this paper we investigate the energy footprint and performance profiling of COSMO-ART on various HPC platforms. This model is an extension of the operational weather forecast model of the German weather service (DWD), ...
