SPEC ACCEL Benchmark Description File

Benchmark Name

126.ge

Benchmark Author

University of Virginia

Benchmark Program General Category

Dense Linear Algebra, Linear Algebra

Benchmark Description

Gaussian Elimination computes result row by row, solving for all of the variables in a linear system. The algorithm must synchronize between iterations, but the values calculated in each iteration can be computed in parallel.

Input Description

This benchmark takes the size of the matrix to factor as input on the command line. It uses an internally generated matrix as data.

Output Description

The solution vector is used as output for validation.

The output file ge.out contains detailed timing information about the run. It also shows which device was selected along with what devices where available to OpenCL.

Programming Language

C++

Known portability issues

None
