NAME
       spmvtest2b - 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 nine point  central  differ-
       ence  scheme, and a vector (1, ..., 1)^T. The FLOPS performance is mea-
       sured as	the average of iter iterations.	 If necessary, one of the fol-
       lowing 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 di-
       mension.	 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
