NAME
x{s,d,c,z}c?blat{1,2,3} - testing programs for blas
SYNOPSIS
x{s,d,c,z}c?blat1
x{s,d,c,z}c?blat{2,3} < parameter file
DESCRIPTION
This manual page documents briefly the blas testing programs. This
manual page was written for the Debian GNU/Linux distribution because
the original programs do not have manual pages.
blas is a library of Basic Linear Algebra routines, accessed through
either a Fortran and/or a C interface. These routines are categorized
into three levels: level1 referring to vecotr-vector operations, level2
to matrix-vector operations, and level3 to matrix-matrix operations.
In addition, all routines are written in four "precisions", single
precision real (s), double precision real (d), cingle precision complex
(c), and double precision complex (z).
The testing binaries examine routines in the level indicated by the
last character in the program name and in the precision indicated by
the second character in the program name. The stem "blat" in the
program name refers to a Fortran interface tester, whereas a "cblat"
stem refers to a C interface tester.
The test programs for levels 2 and 3 read a set of parameters
specifying the problem ranges to examine on standard input. Sample
input files are found in /usr/share/doc/blas-test/examples. Files of
the form {s,d,c,z}in{2,3} are input files for the C interface testing
programs, while files or the form {s,d,c,z}blat{2,3}d are input files
to the Fortran testing programs.
On Debian systems, these programs are dynamically linked against the
blas library. This enables the user to test and compare alternate
versions of the library, such as those provided by atlas, through the
use of the LD_LIBRARY_PATH and LD_PRELOAD environment variables. One
can confirm the versions of the libraries being tested in a given
environment with the aid of the ldd program.
OPTIONS
These programs take no command line options.
