SPEC ACCEL Benchmark Description File

Benchmark Name

357.csp

Benchmark Author

Serial C version was developed the Center for Manycore Programming at Seoul National University and derived from the serial Fortran versions in "NPB3.3-SER" developed by NAS.

OpenACC version was developed by Rengan Xu and Sunita Chandrasekaran from University of Houston.

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 B: reference data of 400 time steps, dt=0.0015 and 64x64x64 grids

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

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

Output Description

It prints out the 5x1 vector in u.

Programming Language

C

Threading Model

OpenACC

Known portability issues

None.
