NAME
spmvtest1 - SpMV kernel benchmark of one dimensional LaplacianSYNOPSIS
spmvtest1 n iter [matrix_type]DESCRIPTION
This program computes the matrix-vector multiply of a discretized one dimensional Laplacian of size n using the three point central difference scheme, and a vector (1, ..., 1)^T. The FLOPS performance is measured as the average of iter iterations. If necessary, one of the following values can be specified by matrix_type:- 0
- Measure the performance for the available matrix storage formats
- 1-11
- The number of the matrix storage format
The value n represents the number of the grid points. See Lis User Guide for more information.
EXIT STATUS
The following exit values are returned:- 0
- The process is normally terminated
- unspecified
- An error occurred
