Aplicación sintética para el estudio de maleabilidad en computación de altas prestaciones

Abstract

Hoy en día, la mejora del rendimiento en los grandes clusters de ordenadores recomienda el desarrollo de aplicaciones maleables. Así, durante la ejecución de estas aplicaciones en un trabajo, el sistema de gestión de recursos (RMS) puede modificar su asignación de recursos, con el fin de aumentar el rendimiento global. Existen diferentes alternativas para completar los distintos pasos en los que se descompone la reasignación de recursos. Para encontrar las mejores alternativas, este trabajo introduce una aplicación sintética iterativa maleable MPI capaz de modificar, en tiempo de ejecución, el número de procesos MPI en función de varios parámetros. La aplicación incluye un módulo de rendimiento para medir el coste de las etapas dentro de los pasos, desde la gestión de los procesos hasta la redistribución de los datos. De este modo, el análisis de diferentes escenarios permitirá concluir cómo debe realizarse la redistribución de datos en diferentes circunstancias.
