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.
