Informática incorpora laboratorios móviles para trabajos experimentales en cátedras

La Facultad cuenta desde el mes de agosto de este año con dos laboratorios móviles con quince computadoras portables cada uno, interconectadas por una red Wi-Fi con acceso a InterNet y con las prestaciones requeridas para la realización de los trabajos experimentales en diferentes cursos de las carreras de Informática. Principalmente, este sistema de Laboratorios Móviles, presenta la ventaja de poder ser trasladado fácilmente de un aula a otra, aportando una capacidad de trabajo de 30 a 60 alumnos, en grupos. Al mismo tiempo, descongestiona el acceso al uso de los Laboratorios de Grado y Posgrado que están actualmente instalados, y brinda a los docentes una mayor posibilidad de planificar trabajos experimentales con los alumnos.Facultad de Informátic

Humans expect generosity

Mechanisms supporting human ultra-cooperativeness are very much subject to debate. One psychological feature likely to be relevant is the formation of expectations, particularly about receiving cooperative or generous behavior from others. Without such expectations, social life will be seriously impeded and, in turn, expectations leading to satisfactory interactions can become norms and institutionalize cooperation. In this paper, we assess people's expectations of generosity in a series of controlled experiments using the dictator game. Despite differences in respective roles, involvement in the game, degree of social distance or variation of stakes, the results are conclusive: subjects seldom predict that dictators will behave selfishly (by choosing the Nash equilibrium action, namely giving nothing). The majority of subjects expect that dictators will choose the equal split. This implies that generous behavior is not only observed in the lab, but also expected by subjects. In addition, expectations are accurate, matching closely the donations observed and showing that as a society we have a good grasp of how we interact. Finally, correlation between expectations and actual behavior suggests that expectations can be an important ingredient of generous or cooperative behavior.This project has been circulating over the last years under different titles.

Expected Generosity in One-shot Interactions

What do we expect of others? Do we expect people to be generous? If so, can we attribute this expected generosity to wishful thinking? Are our expectations, to some extent, related to our personal involvement in the outcome or the size of the stakes? This study investigates expectations on generosity by means of a series of controlled experiments. A total of 205 subjects were recruited and their expectations about the dictator's behavior in the dictator game were elicited. Despite differences in the roles, involvement in the game, the degree of social distance or the variation of stakes, the results are conclusive: subjects seldom predict that dictators will behave selfishly, and the majority of subjects expect that dictators will choose the equal split. This, in turn, implies that generous behavior is not only observed in the lab, but also expected by subjects

Cloud computing en aplicaciones científicas : Arquitecturas, configuración y análisis experimental de costo/performance

El objetivo principal de esta Tesina ha sido desplegar un Cloud Privado con el propósito de analizar e investigar la arquitectura Cloud Computing para ambientes de cómputo científico, teniendo en cuenta el auge de esta arquitectura. Resulta de interés estudiar la evolución de las tecnologías de cómputo Cluster y Grid hacia Cloud. También interesa realizar el despliegue un Cloud Privado utilizando un gestor Open Source y llevar a cabo la ejecución de algunas aplicaciones paralelas de cómputo científico que utilizan pasaje de mensajes MPI. Como casos de prueba se han seleccionado las aplicaciones que resuelven el problema de las N-Reinas y los NAS Parallel Benchmarks. Cabe destacar que las aplicaciones antes mencionadas poseen diversas características con respecto al tiempo de procesamiento y de comunicación. Finalmente, analizar los tiempos de ejecución y calcular el overhead que introduce la arquitectura Cloud.Facultad de Informátic

What do we expect of others?

We report experimental data on expectations about generosity in a dictator game in which dictators first divide the pie and then make a guess about the donation of other dictators. In our experiment, recipients have to guess the donation that they are going to receive from their own dictator as well as the donation of other dictator, whose choice does not affect their own payoffs. Our findings indicate that property rights are important to explain guesses, as dictators predict a smaller donation from other dictators than recipients do. We also observe that the involvement in the game is crucial as recipients expect other dictators to be more generous than their own dictator. When we compare guesses with actual donations, we see that dictators' guesses are positively correlated with their own transfer and that recipients overestimate the kindness of other dictators, as they expect them to be more kind than what they actually are

Parallel processing DNA sequences on multicluster and grid architectures : Software overhead

A DNA sequence analysis parallelization in large databases using cluster, multi-cluster, and GRID is presented. Achievable speedup, scalability, and overhead introduced by communications are discussed, and the impact of the Grid middleware on the performance obtained with clusters is detailed. The experimental work carried out with homogeneous and heterogeneous clusters is presented, along with a comparison of the results obtained when migrating the algorithms to a GRID. Finally, current lines of work related to the study of models and paradigms for the resolution of parallel algorithms on GRID architectures are presented.Workshop de Procesamiento Distribuido y Paralelo (WPDP)Red de Universidades con Carreras en Informática (RedUNCI
