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 Guide for more information.

Exit Status

The following exit values are returned:

0
The process is normally terminated
unspecified
An error occurred
