spmvtest2(1)

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
