TITLE: "Towards the Dynamic Selection of Parallel Linear Solvers Based on Performance and Power Considerations"

ABSTRACT: The solution of large-scale linear systems often dominates the overall execution of parallel applications based on partial differential equations. Moreover, it is impossible to know a priori which of many different algorithms performs best for a given problem. This poster describes our approach to incorporating power considerations into the dynamic selection of preconditioned Krylov methods. This work forms part of a multi-institutional effort to develop infrastructure for computational quality of service for parallel scientific applications.
