Name
spmvtest2 - SpMV kernel benchmark of two dimensional Laplacian
Synopsis
spmvtest1 m n iter [matrix_type]
Description
This program computes the matrix-vector multiply of a discretized two dimensional Laplacian of size mn using the five 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 values m and n represent the numbers of the grid points in each dimension. See Lis User Manual for more information.
Exit Status
The following exit values are returned:
- 0
- The process is normally terminated
- unspecified
- An error occurred
