Data For: Scalable And Live Trace Processing With Kieker Utilizing Cloud Computing

Florian Fittkau, Jan Waller, Peer Brauer & Wilhelm Hasselbring
Knowledge of the internal behavior of applications often gets lost over the years. This circumstance can arise, for example, from missing documentation. Application-level monitoring, e.g., provided by Kieker, can help with the comprehension of such internal behavior. However, it can have large impact on the performance of the monitored system. High-throughput processing of traces is required by projects where millions of events per second must be processed live. In the cloud, such processing requires scaling...

Data For: A Benchmark Engineering Methodology To Measure The Overhead Of Application-Level Monitoring

Jan Waller & Wilhelm Hasselbring
Application-level monitoring frameworks, such as Kieker, provide insight into the inner workings and the dynamic behavior of software systems. However, depending on the number of monitoring probes used, these frameworks may introduce significant runtime overhead. Consequently, planning the instrumentation of continuously operating software systems requires detailed knowledge of the performance impact of each monitoring probe. In this paper, we present our benchmark engineering approach to quantify the monitoring overhead caused by each probe under controlled...

What Causes The Kanizsa Stimulus To Break Interocular Suppression?

Pieter Moors, Sanne van Crombruggen, Johan Wagemans, Raymond van Ee & Lee de-Wit
A regular, grouped Kanizsa triangle has been shown to break through interocular suppression faster than an ungrouped, random Kanizsa triangle [Wang et al., 2012, PLoS ONE, 7(6): e40106]. In an earlier neuropsychological study Conci et al. [2009, Neuropsychologia, 47, 726-732] showed that low-level collinear contour facilitation and high-level surface filling-in both contribute separately to a reduction in extinction in patients with visual neglect when viewing Kanizsa stimuli. Since Wang et al. (2012) did not include...

Diagramas Y Biopoder. Discusiones Sobre Las Sociedades De Control.

Adán Salinas Araya
Resumen: El artículo pretende una discusión con la idea de sociedad de control, en el marco de un análisis biopolítico. Para ello propone un doble juego. Por una parte, explicitar las dificultades de tal categoría en las propuestas de Hardt, Negri y Deleuze; y en segundo lugar, releer tales propuestas a partir del análisis del neoliberalismo, propuesto por Foucault. La hipótesis básica es que las indecisiones y dificultades de tal categoría, muestran la necesidad de...

Computational Screening Of Functionalized Zinc Porphyrins For Dye Sensitized Solar Cells

Kristian Baruël Ørnsø, Juan Maria Garcia-Lastra & Kristian Sommer Thygesen
Poster presenting our recent paper in which we have performed a computational Density Functional Theory based screening of 1029 functionalized zinc porphyrins dyes for use in Dye Sensitized Solar Cells. We present the fundamental and optical gaps and use these to asign a level alignment quality to the dye candidates.

Computational Literary Genre Stylistics

Christof Schöch
The project in a nutshell: This project will investigate the relation between literary genres (generic facets) and style (stylistic attributes). Analyses are based on large collections of literary texts and use or develop state-of-the-art methods in computational stylistics and text analysis. This will enable the project to combine attention to minute stylistic details with the investigation of large trends and patterns in literary history. What does the project aim to accomplish? The project brings together...

Benchmark For: A Comparison Of The Influence Of Different Multi-Core Processors On The Runtime Overhead For Application-Level Monitoring

Jan Waller & Wilhelm Hasselbring
Application-level monitoring is required for continuously operating software systems to maintain their performance and availability at runtime. Performance monitoring of software systems requires storing time series data in a monitoring log or stream. Such monitoring may cause a significant runtime overhead to the monitored system. In this paper, we evaluate the influence of multi-core processors on the overhead of the Kieker application-level monitoring framework. We present a breakdown of the monitoring overhead into three portions...

Vectorization With Haswell And Cilkplus

Fumero Alfonso Juan José & Nowak Andrzej
Project Specification:
This project concerns the parallel computing and vectorization field for Physics Computing at CERN. The document summarises the results and experience from vectorization activities and an initial evaluation of the CilkPlus technology with two different benchmarks from CERN.
Abstract:
With the release of the Intel Sandy Bridge processor, vectorization ceased to be a “nice to have” feature and became a necessity. This work is focused on optimization, running comparative measurements of available vectorization...

High-resolution records of fluid extraction at two wells on the grounds of the Pathfinder Ranch, located within a few hundred meters of two Plate Boundary Observatory borehole strainmeters, namely B089 and B082. The records begin in early 2011 and end in late 2013. These data accompany the following publication: Barbour, A. J., & Wyatt, F. K. (2014). Modeling strain and pore pressure associated with fluid extraction: The Pathfinder Ranch experiment. Journal of Geophysical Research: Solid...

El Hombre Empresa Como Proyecto Ético-Político. Lecturas De Michel Foucault

Adán Salinas
Resumen: El artículo pretende explorar la categoría de hombre-empresa, que Foucault propuso como uno de los dispositivos o interfaces claves del poder en el contexto del neoliberalismo. A través de esta categoría se muestra una particular forma de poder sobre la vida, o biopoder, que es distinto al tipo de poder de la sociedad disciplinaria, aunque tiene relaciones de continuidad con este último. En tal sentido el artículo maneja la hipótesis de la superposición o...

Improved Metrics Collection And Correlation For The Cern Cloud Storage Test Framework

Carolina Lindqvist, Maitane Zotes & Seppo Heikkila
Storage space is one of the most important ingredients that the European Organization for Nuclear Research (CERN) needs for its experiments and operation. Part of the Data & Storage Services (IT-DSS) group’s work at CERN is focused on testing and evaluating the cloud storage system that is provided by the openlab partner Huawei, Huawei Universal Disk Storage System (UDS). As a whole, the system consists of both software and hardware.
The objective of the Huawei-CERN...

Towards A Generic Model For Figure-Ground Segmentation

Jonas Kubilius, Johan Wagemans & Hans P. Op de Beeck
While multiple studies investigate the properties of the earliest and final stages of visual information processing, the underlying transformations leading from simple edge detection to object recognition remain seemingly intractable. To tackle this problem, we take a step back and ask what mechanisms could lead to a successful figure-ground segmentation of a given image. We propose the following conceptual framework: (i) alternating steps of feature detection and feature pooling (grouping) in a hierarchical manner; (ii)...
