Area 4 Working Note 16: Implementation and Performance of Scalable Scientiic Library Subroutines on Fujitsu's Vpp500 Parallel-vector Supercomputer

We report progress to date on our project to implement high-impact scientiic subroutines on Fujitsu's parallel-vector VPP500. Areas covered in the project are generally between the level of basic building blocks and complete applications, including such things as random number generators, fast Fourier transforms, various linear equation solvers, and eigenvalue solvers. Highlights so far include...

Distributedd Memoryy Implementationn off Multigridd Methodss for Groundwaterr Floww Problemss Withh Roughh Coefficients

In this paper we present parallel solvers for large linear systems arising from the finite–element discretization of three–dimensional groundwater flow problems. We have tested our parallel implementations on the Intel Paragon XP/S 150 supercomputer using up to 1024 parallel processors. Our solvers are based on multigrid and Krylov subspace methods. Our goal is to combine powerful algorithms an...

Factorization-based Sparse Solvers and Preconditioners

Efficient solution of large-scale, ill-conditioned and highly-indefinite algebraic equations often relies on high quality preconditioners together with iterative solvers. Because of their robustness, factorizationbased algorithms play a significant role in developing scalable solvers. We discuss the state-of-the-art, high performance sparse factorization techniques which are used to build spars...

Comparative analysis of high performance solvers for solving Stokes equation

We consider the time dependent Stokes equation on a finite time interval and on a uniform rectangular mesh, written in terms of velocity and pressure. A parallel algorithm based on a direction splitting approach is implemented. We are targeting the massively parallel computer as well as clusters of many-core nodes. The implementation is tested on the IBM Blue Gene/P supercomputer and two Linux ...
