hpcg_spmvtest(1) Utility Commands hpcg_spmvtest(1) NAME hpcg_spmvtest - SpMV kernel benchmark for high performance conjugate gradient SYNOPSIS hpcg_spmvtest l m n iter [matrix_type] DESCRIPTION This program computes the matrix-vector multiply of a discretized three dimensional Laplacian of size lmn using the twenty-seven 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 values l, 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: 0 The process is normally terminated unspecified An error occurred SEE ALSO lis(3), lsolve(1), esolve(1), hpcg_kernel(1) spmvtest1(1), sp- mvtest2(1), spmvtest2b(1), spmvtest3(1), spmvtest3b(1), spmvtest4(1), spmvtest5(1) http://www.ssisc.org/lis/ Man Page 26 Mar 2014 hpcg_spmvtest(1)
