NAME

hpcg_spmvtest - SpMV kernel benchmark for high performance conjugate gradient

SYNOPSIS

hpcg_spmvtest l m n iter [matrix_type]

DESCRIPTION

This program computes the matrix-vector multiply of a discretized three dimensional Laplacian of size lmn using the twenty-seven 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 l, 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
