Load balancing for constraint solving with GPUs

Solving a complex Constraint Satisfaction Problem (CSP) is a computationally hard task which may require a considerable amount of time. Parallelism has been applied successfully to the job and there are already many applications capable of harnessing the parallel power of modern CPUs to speed up the solving process. Current Graphics Processing Units (GPUs), containing from a few hundred to a few thousand cores, possess a level of parallelism that surpasses that of CPUs and there are much less applications capable of solving CSPs on GPUs, leaving space for further improvement. This paper describes work in progress in the solving of CSPs on GPUs, CPUs and other devices, such as Intel Many Integrated Cores (MICs), in parallel. It presents the gains obtained when applying more devices to solve some problems and the main challenges that must be faced when using devices with as different architectures as CPUs and GPUs, with a greater focus on how to effectively achieve good load balancing between such heterogeneous devices.

ORDENAMIENTO DEL TERRITORIO LOCAL ASISTIDO A TRAVES DE UN SISTEMA DE INFORMACIÓN GEOGRÁFICA.

El presente artículo muestra la aplicación de un Sistema de Información Geográfica (SIG) con una interfase con manejador de base de datos. El SIG utilizado es de modelo raster sin la capacidad de desarrollar una base de datos descriptiva. La aplicación desarrollada es conocida como Sistema de Información Geográfica para Gobiernos Locales (SIGGLO)y el área donde se implementó fue en el cantón de santo Domingo de la provincia de Heredia. En el apartado Los Planes de ordenamiento Territorial se discute sobre la utilidad que posee este tipo de instrumentos, que regulan el ordenamiento a nivel local y en forma paralela los autores presentan sus inquietudes del porqué los planes reguladores no han tenido el éxito deseado. Posteriormente, se presenta la visión de los autores sobre Los Planes de ordenamiento Manuales vs. Automatizados, el cual permite presentar las ventajas y desventajas que poseen los SiGs para implementar un Plan de Ordenamiento a través de esta tecnología. Seguidamente se presenta en detalle la experiencia obtenida con el SIGGLO, donde se explica la utilización del SIG y de un paquete de digitalización para combinar luego ambos con un manejador de bases de datos. Por último, se presentan una serie de restricciones que tiene el SIGGLO, también las recomendaciones que se deberían considerar al implementar un nuevo proyecto bajo la metodología del SIGGLO. ABSTRACTThe present article presents an application of a data base management system interfacing with a Geographical Information System (GIS). The utilized GIS for the project is a raster based system without the ability to develop a descriptive data base. This system is called Geographical Information System for Local Governments (SIGGLO) and was implemented in the canton of Santo Domingo, Costa Rica. It is mentioned in Territorial Organization Plans the utility that GIS systems have in regulating organization on a local level. In parallel form, the authors present their doubts of why these regulatory plans have not had the desired success. Afterwards, the authors present their vision of an Organization Plan for Manual and Automated functions which permit the presentation of the advantages and disadvantages that contain GIS in order to implement a Organization Plan with these technologies. Following this is a detailed presentation of the experience obtained with SIGGLO and where it is explained the utility of the GIS and of a digitizing software package which was later combined in the data base management system. Finally, a series of restrictions is presented that SIGGLO has which also contains details of recommendations that should be considered upon implementing a new project under the SIGGLO methodology.

A MODIFICAÇÃO DA PAISAGEM DO LITORAL DO PARANÁ A PARTIR DOS PROCESSOS DE OCUPAÇÃO E URBANIZAÇÃO: PAISAGEM, CULTURA E ARTE

Este texto trata dos processos de modificação da paisagem da zona costeira paranaense, desde a ocupação deste território até a atualidade. Tem como linha de condução paralela a este processo, a produção artística paranaense tendo como referencial a representação imagética encontrada nas aquarelas, gravuras e pinturas produzidas no e sobre o litoral do Paraná, neste mesmo período de tempo. O entendimento ampliado da arte unido ao entendimento da história do litoral do Paraná, sua ocupação, as mudanças de sua paisagem a partir de sua colonização e urbanização; a maneira como são hoje utilizados estes espaços urbanos e o entendimento das dificuldades advindas da falta de um planejamento urbano no litoral paranaense possibilitam compreender cada vez mais suas especificidades, características e idiossincrasias.

O controle de convencionalidade no Brasil: da Convenção de Viena ao Bloco de Constitucionalidade

ResumenEste artículo tiene como objetivo principal analizar una nueva tesis introducida recientemente en Brasil llamada control de convencionalidad, paralela y simultánea a la del control de constitucionalidad, y cómo podrían los jueces y las juezas y abogados y abogadas hacer un buen uso de ellos en sus actividades diarias. Como este nuevo “poder” surgió en el sistema jurídico brasileño a partir de la enmienda constitucional número 45 de 2004, haremos unaretrospectiva histórica, a través de un análisis de la jerarquía de los tratados de derechos humanos, al tener como base la jurisprudencia del Tribunal Supremo y la doctrina portuguesadel bloque de constitucionalidad.Palabras clave: Control de convencionalidad, bloque de constitucionalidad, Derechos Humanos, tratados internacionales. ResumoO presente artigo tem por escopo a análise da possibilidade de utilização, por parte dos magistrados brasileiros, do chamado “Controle de Convencionalidade”, paralelo e concomitante ao controle de constitucionalidade. Tendo tal prerrogativa surgido a partir da Emenda Constitucional Nº 45, far-se-á um retrospecto histórico da hierarquia dos tratados internacionais de Direitos Humanos no ordenamento pátrio, analisando a jurisprudência do SupremoTribunal Federal, bem como a utilização do Bloco de Constitucionalidade como paradigma de controle da constitucionalidade-convencionalidade das leis.Palavras chave: controle de convencionalidade, Bloco de Constitucionalidade, Direitos Humanos, tratados internacionais.

AN ANALYSIS OF THE NOVEL “A GENTLE CREATURE”

This paper has the objective to analyze the novel “A Gentle Creature”, of the Russian novelist Fyodor Dostoevsky, using the theoretical concepts covered in the text “1874 – Three Novellas, or ‘What Happened?’” (1996), which makes up the volume 3 of the work A Thousand Plateaus: Capitalism and Schizophrenia, of the French philosophers Gilles Deleuze and Félix Guattari. These concepts can be triggered to realize the approach of the question about the segmentarity lines, which make it possible to make the observation of the changes of state that have occurred with the characters in a literary work, of the ways how undertake movements of territorialization, deterritorialization and reterritorialization in development of such segmentarity lines, which are termed as hard or molar, molecular or malleable, and trail, having the view that it is through them that these characters go through this transformation process. Starting from this analysis, will pick up, too, to connect the theory of these two French philosophers with polyphonic theory presented by Russian philosopher and theorist of language Mikhail Bakhtin in the book Problems of Dostoevsky's poetics (1997), which investigate the concept of polyphony, from Dostoevsky's work, being, among other texts analyzed the Russian novelist, novel to be studied in this work. And the perspective that arises in the analysis proposed in this article, what is sought is to conduct a parallel investigation of how both theories have the possibility of development work in the observation of the characteristics of a literary work, and these characteristics likely to these concepts are related to the lines of segmentarity deleuzo-guattarianas and Bakhtin's polyphony.
