    Beschreibung: The prototype implementation of an expert system was developed to assist the user in the computer aided parallelization process. The system interfaces to tools for automatic parallelization and performance analysis. By fusing static program structure information and dynamic performance analysis data the expert system can help the user to filter, correlate, and interpret the data gathered by the existing tools. Sections of the code that show poor performance and require further attention are rapidly identified and suggestions for improvements are presented to the user. In this paper we describe the components of the expert system and discuss its interface to the existing tools. We present a case study to demonstrate the successful use in full scale scientific applications.

    Beschreibung: Parallel programming paradigms include process level parallelism, thread level parallelization, and multilevel parallelism. This viewgraph presentation describes a detailed performance analysis of these paradigms for Shared Memory Architecture (SMA). This analysis uses the Paraver Performance Analysis System. The presentation includes diagrams of a flow of useful computations.

    Beschreibung: When porting sequential applications to parallel computer architectures, the program developer will typically go through several cycles of source code optimization and performance analysis. We have started a project to develop an environment where the user can jointly navigate through program structure and performance data information in order to make efficient optimization decisions. In a prototype implementation we have interfaced the CAPO computer aided parallelization tool with the Paraver performance analysis tool. We describe both tools and their interface and give an example for how the interface helps within the program development cycle of a benchmark code.

    Beschreibung: In this paper we describe how to apply powerful performance analysis techniques to understand the behavior of multilevel parallel applications. We use the Paraver/OMPItrace performance analysis system for our study. This system consists of two major components: The OMPItrace dynamic instrumentation mechanism, which allows the tracing of processes and threads and the Paraver graphical user interface for inspection and analyses of the generated traces. We describe how to use the system to conduct a detailed comparative study of a benchmark code implemented in five different programming paradigms applicable for shared memory

    Beschreibung: Se determinó la biomasa del camarón rosado Farfantepenaeus notialis presente en el golfo de Ana María durante el periodo 1997-2010 mediante análisis estadístico de captura por edades (SCA). Esta se incrementó a partir del año 2008 como respuesta al aumento del reclutamiento, cuyo promedio anual presenta sus mayores valores en julio, noviembre y marzo. La entrada de reclutas (pre-adultos) al área de pesca ocurre por dos zonas principales, frente a los cayos de Ana María, y en Sta. Cruz Abajo, al norte de la porción sur de los cayos de las Doce Leguas. Una pesquería a finales del año puede provocar una sobrepesca del crecimiento y afectar la biomasa disponible para el siguiente año.
    Beschreibung: The biomass of the pink shrimp Farfantepenaeus notialis present in Ana María gulf during the period 1997-2010, was determined by means of statistical analysis of capture for ages (SCA). The biomass was increased from the year 2008 due to the increase of the recruitment, which shows its biggest average annual values in July, November and March. The recruitspre-adults arrival to the fishing area occurs by two main zones, in front of Ana María keys, and in Sta. Cruz Abajo, at North of the South portion of the Doce Leguas keys. A fishery at the end of the year may provoke an over fishing of the growth and to affect the available biomass for the following year.

Esta se incrementó a partir del año 2008 como respuesta al aumento del reclutamiento, cuyo promedio anual presenta sus mayores valores durante el segundo semestre del año. La entrada de reclutas (pre-adultos) al área de pesca ocurre por dos zonas principales, frente a los cayos de Ana María, y en Sta.

    Beschreibung: It was determined the biomass of pink shrimp Farfantepenaeus notialis present in the Gulf of Ana Maria during the period 1997-2010, by means of statistical analysis of catch per ages (SCA). The biomass increased from 2008 as a response to the increment in the recruitment, which showed its highest average annual values during the second semester of that year. The input of recruits (pre-adults) to the fishing area occurs by two main zones, in front of Ana Maria keys and in Santa Cruz Abajo, North of the southern portion of Doce Leguas keys. Fishing at the end of the year may cause an overfishing of the growth, thus affecting the available biomass for the following year.

    Beschreibung: Con el propósito de conocer el nivel de biomasa del camarón rosado (Farfantepenaeus notialis) y la variación espacio temporal de la población en la zona de pesca de la Empresa Pesquera de Granma, se analizó la información de los cruceros de prospección mensuales realizados durante los años 2009, 2010 y enero del 2011. La composición por talla muestra medias de 8.7 y 8.5 cm (largo cubano) con tallas máximas de 14.7 y 15.2 cm. En el golfo de Guacanayabo el desove de la especie ocurre durante los meses de marzo a julio. El reclutamiento muestra dos etapas, la primera en enero-febrero y la segunda en agostoseptiembre pudiendo ocurrir adelanto en los meses como se apreció en julio del año 2009. El reclutamiento se manifiesta en la zona oriental del golfo de Guacanayabo desde la Boca del Cauto hasta la ensenada de Gua, incluyendo los cayos de Manzanillo, pudiendo desplazarse al W de la ensenada de Gua. El golfo de Guacanayabo muestra una biomasa del orden de 600 t y los máximos de biomasa durante 2009, 2010 y 2011 se presentan en la Zona III en febrero, abril y enero respectivamente. La biomasa disminuye en la medida en que actúa fundamentalmente la mortalidad natural.
    Beschreibung: Aimed to know the biomass level of pink shrimp (Farfantepenaeus notialis) and the space-time variation of the population in the fishing area of EPIGRAN enterprise, the information of monthly research cruises was analyzed during years 2009, 2010 and 2011 (January). Size composition shows a mean size of 8.7 and 8.5 cm (Cuban length) with maximum sizes of 14.7 and 15.2 in 2009 and 2010 respectively. Taking into account the maxima values of gonadal maturation for areas, the Guacanayabo gulf shows that spawning takes place during the months of March to July. The recruitment confirm two stages during the year, the first one during January-February and the second during August-September, being noted that a recruitment advance may occur as observed in July, 2009. During the studied years, recruitment is mainly observed in the eastern area of Guacanayabo gulf, from the Boca del Cauto until Gua bay, including the Manzanillo keys, and may move to the west of Gua bay. Gulf of Guacanayabo shows a biomass in the order of 600 t, with maxima values during 2009, 2010 and 2011 occurring in the Zone III in February, April and January respectively. A biomass decrease is observed later due mainly as natural mortality takes place.
