spmvtest1(1) - Linux man page
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 dimensional 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 Manual for more information.
Exit Status
The following exit values are returned:
- 0
- The process is normally terminated
- unspecified
- An
error occurred
