spmvtest2 — SpMV kernel benchmark of two dimensional Laplacian


spmvtest1 m n iter [matrix_type]


This program computes the matrix-vector multiply of a discretized  two dimensional Laplacian of size mn using the five 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:


Measure the performance for the available matrix storage formats


The number of the matrix storage format

The values m and n represent the numbers of the grid points in each dimension. See Lis User Guide for more information.

Exit Status

The following exit values are returned:


The process is normally terminated


An error occurred
