Benchmark Problem specs Comments Status
Sweep3D NA
  • Solves a 3D neutron transport problem.
  • Original Fortran code is available here
    		• Done.
    Available here.
    SP
  • problem size=50
  • procs=4, 9, 16.
  • Part of the NAS Parallel Benchmark 2 suite.
  • Implements a 3D Multi-partition algorithm for the solution of the uncoupled systems of linear equations resulting from Beam-Warming approximate factorization (whatever that means).
  • Original Fortran code is available somewhere here
    		• Done.
    Available here.
    BT
  • Part of the NAS Parallel Benchmark 2 suite.
  • Similar to LU, but core of the BT solution phase involves solution of (5x5)-systems of equations and multiplication of (5x5) matrices, both of which are part of the application of GE to the block-tridiagonal systems.
  • Original Fortran code is available somewhere here
    		• In progress
    MG
  • problem size=64^3
  • nit=50
  • procs=4,8,16.
  • Part of the NAS Parallel Benchmark 2 suite.
  • Demonstrates the capabilities of a very simple multigrid solver in computing a three dimensional potential field.
  • Original Fortran code is available somewhere here
    		• In progress
    LU
  • problem size=48^3
  • iter=50
  • isiz1=24, isiz2=24
  • procs=4, 8, 16.
  • Part of the NAS Parallel Benchmark 2 suite.
  • Solves a finite difference discretization of the 3-D compressible Navier-Stokes equations through a block-lower-triangular block-upper-triangular approximate factorization of the original difference scheme.
  • Original Fortran code is available somewhere here
    		• In progress
    SAMPLE NA
  • Synthetic application that executes wavefront and nearest-neighbour message-passing.
  • Package includes MPI and MPI-SIM versions.
    		• Done.

    FFT and Gauss-Jordan elimination NA
  • Two applications for running a Fast Fourier Transform and a Gauss-Jordan linear equation algorithm.
  • Package includes MPI and MPI-SIM versions.
    		• Done.
    Available here (7K)
    Out-of-core matrix multiplication NA
  • Performs out-of-core matrix multiplication. Requires MPI-IO.
