NAME
     hpcg_spmvtest - SpMV kernel benchmark for high performance conjugate gradi-
     ent

SYNOPSIS
     hpcg_spmvtest l m n iter [matrix_type]

DESCRIPTION
     This program computes the matrix-vector multiply of a discretized three di-
     mensional	Laplacian  of size lmn using the twenty-seven point central dif-
     ference scheme, and a vector (1, ..., 1)^T. The FLOPS performance	is  mea-
     sured  as the average of iter iterations.	If necessary, one of the follow-
     ing 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 l, 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
