SYNOPSIS

10       spmvtest1 m n iter [matrix_type]

DESCRIPTION

14       This  program  computes the matrix-vector multiply of a discretized two
15       dimensional Laplacian of size mn using the nine point  central  differ‐
16       ence  scheme, and a vector (1, ..., 1)^T. The FLOPS performance is mea‐
17       sured as the average of iter iterations.  If necessary, one of the fol‐
18       lowing values can be specified by matrix_type:
19
20       0      Measure the performance for the available matrix storage formats
21
22       1-11   The number of the matrix storage format
23
24       The  values  m  and  n represent the numbers of the grid points in each
25       dimension.  See Lis User Guide for more information.
