Benchmark Name

456.spF

Benchmark Author

SP is from the "NPB3.3-SER" benchmark suite developed by NAS.

Initial port to OpenMP by Alexander Grund

Benchmark Program General Category

Scalar Penta-diagonal solver

Benchmark Description

This performs a synthetic CFD problem by solving multiple, independent systems of non diagonally dominant, scalar, pentadiagonal equations.

Input Description

The input dataset size is comprised of W, A through E classes. We have used 3 classes in our experiments.

Class A: reference data of 100 time steps, dt=0.015 and 12x12x12 grids

Class C: reference data of 400 time steps, dt=0.00067 and 162x162x162 grids

Class D: reference data of 600 time steps, dt=0.0003 and 360x360x360 grids

Class A is used by the test workload, Class C by train, and Class D by ref.

Output Description

It prints out the 5x1 vector in u.

Programming Language

Fortran

Known Portability Issues

None.
