NAME
     spmvtest1 - SpMV kernel benchmark of one dimensional Laplacian

SYNOPSIS
     spmvtest1 n iter [matrix_type]

DESCRIPTION
     This  program  computes the matrix-vector multiply of a discretized one di-
     mensional Laplacian of size n using  the  three  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  value  n represents the number of the grid points.  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
