An Integrated Software Development Model for Heterogeneous High Performance Computing

The last few decades have seen an impressive developments in every aspect of parallel computing technology; viz. processing and storage technology, interconnect technology and software technology. Although these systems incorporate large amount of computing power, they are not general enough to efficiently support today's computation-intensive problems (e.g. the Grand Challenges), that warrant multiple computational models and levels of parallelism. We believe that the future of parallel computing lies in the integration of the plethora of "specialized" architectures into a single Heterogeneous High Performance Computing (HHPC) environment that allows them to cooperate in solving complex problems. Software development in any Parallel/Distributed environment is a non-trivial process and requires a thorough understanding of the application and the architecture. This problem further intensifies as systems evolve into HHPC environments. The objective of this paper is to formalize the softw..

PACFEST : enabling technologies in the war on terrorism in the Pacific region.

On October 22-24, 2003, about 40 experts involved in various aspects of homeland security from the United States and four other Pacific region countries meet in Kihei, Hawaii to engage in a free-wheeling discussion and brainstorm (a 'fest') of the role that technology could play in winning the war on terrorism in the Pacific region. The result of this exercise is a concise and relatively thorough definition of the terrorism problem in the Pacific region, emphasizing the issues unique to Island nations in the Pacific setting, along with an action plan for developing working demonstrators of advanced technological solutions to these issues. In this approach, the participants were asked to view the problem and their potential solutions from multiple perspectives, and then to identify barriers (especially social and policy barriers) to any proposed technological solution. The final step was to create a roadmap for further action. This roadmap includes plans to: (1) create a conceptual monitoring and tracking system for people and things moving around the region that would be 'scale free', and develop a simple concept demonstrator; (2) pursue the development of a system to improve local terrorism context information, perhaps through the creation of an information clearinghouse for Pacific law enforcement; (3) explore the implementation of a Hawaii based pilot system to explore hypothetical terrorist scenarios and the development of fusion and analysis tools to work with this data (Sandia); and (4) share information concerning the numerous activities ongoing at various organizations around the understanding and modeling of terrorist behavior

Structural and functional properties of a probabilistic model of neuronal connectivity in a simple locomotor network.

Although, in most animals, brain connectivity varies between individuals, behaviour is often similar across a species. What fundamental structural properties are shared across individual networks that define this behaviour? We describe a probabilistic model of connectivity in the hatchling Xenopus tadpole spinal cord which, when combined with a spiking model, reliably produces rhythmic activity corresponding to swimming. The probabilistic model allows calculation of structural characteristics that reflect common network properties, independent of individual network realisations. We use the structural characteristics to study examples of neuronal dynamics, in the complete network and various sub-networks, and this allows us to explain the basis for key experimental findings, and make predictions for experiments. We also study how structural and functional features differ between detailed anatomical connectomes and those generated by our new, simpler, model

Consorcio para la colaboración en I+D+I en Temas de Cloud Computing, Big Data y Emerging Topics (CCC-BD&ET) : Proyecto Integrador: “Transformación Digital en la incorporación de la Resiliencia como un Key Performance Indicator de Prestaciones Sociales (KPIS)”

El Consorcio de I+D+i en Cloud Computing, Big Data & Emerging Topics (CCC-BD&ET) es una iniciativa para fomentar y formalizar la colaboración existente entre grupos de investigación de varias universidades en temáticas vinculadas a Cloud Computing, al Análisis Masivo de Datos y a Tópicos Emergentes, como las tecnologías 4.0, entre otros. Estas temáticas, y su integración, han adquirido creciente importancia por su aplicación en dominios de alto impacto como las ciudades inteligentes, la internet de las cosas, los sistemas de e-health y los basados en tecnologías de block-chain. Los integrantes del consorcio, provenientes mayoritariamente de Argentina, Chile y España han tenido, a lo largo de los años, diversas experiencias de trabajo conjunto que fueron consolidadas a partir de la organización y realización de las Jornadas de Cloud Computing-Big Data & Emerging Topics (JCC-BD&ET) llevadas a cabo en la Universidad Nacional de La Plata (Argentina). La constitución de este Consorcio, reafirma y formaliza estas líneas de colaboración proponiendo acciones de cooperación académica vinculadas con la formación de recursos humanos, la formulación y ejecución de proyectos conjuntos, y la vinculación con empresas y organismos relacionados con la industria informática, entre otras. Este trabajo presenta el avance del consorcio en la definición de un proyecto integrador que tiene como eje la Resiliencia para la Transformación Digital.Red de Universidades con Carreras en Informátic
