Multigrid for Matrix-Free Finite Element Computations on Graphics Processors
In this paper, we consider matrix-free finite-element techniques for efficient numerical solution of partial differential equations on modern manycore processors such as graphics cards. We present a GPU parallelization of a completely matrix-free geometric multigrid iterative solver, with support for general curved and adaptively refined meshes with hanging nodes. Comparing our implementation r...
متن کاملAdjacency-based data reordering algorithm for acceleration of finite element computations
Effective use of the processor memory hierarchy is an important issue in high performance computing. In this work, a part level mesh topological traversal algorithm is used to define a reordering of both mesh vertices and regions that increases the spatial locality of data and improves overall cache utilization during on processor finite element calculations. Examples based on adaptively create...
متن کاملAdditive Preconditioning for Matrix Computations
Versus the customary preconditioners, our weakly random ones are generated more readily and for a much larger class of input matrices. Furthermore our preconditioners have a wider range of applications, in particular to linear systems with rectangular and rank deficient coefficient matrices and to eigen-solving. We study the generation of such preconditioners and their impact on conditioning of...
متن کاملFuzzy models for precision measurements
Engineering and scienti c measurement results of continuous quantities are not precise numbers but more or less non-precise. Therefore so-called non-precise numbers are necessary to describe measurement results. Non-precise numbers are special fuzzy subsets of the set of real numbers. For vector quantities so-called fuzzy vectors are the best up to date model for related measurements.
متن کاملOptical methods for precision measurements
Contactless measuring techniques are becoming increasingly important for industrial applications . The use of a laser, solid-state detector arrays and powerful small computers leads to a very efficient fringe analysis in holography as well as in Moire and speckle techniques . Due to the computer analysis, much more information can be extracted from interferograms, leading to higher sensitivitie...
