SYNOPSIS

DESCRIPTION

15       This program computes the matrix-vector multiply of a discretized three
16       dimensional  Laplacian of size lmn using the twenty-seven point central
17       difference scheme, and a vector (1, ..., 1)^T. The FLOPS performance is
18       measured  as  the average of iter iterations.  If necessary, one of the
19       following values can be specified by matrix_type:
20
21       0      Measure the performance for the available matrix storage formats
22
23       1-11   The number of the matrix storage format
24
25       The values l, m and n represent the numbers of the grid points in  each
26       dimension.  See Lis User Guide for more information.
