%description
The ATLAS (Automatically Tuned Linear Algebra Software) project is an
ongoing research effort focusing on applying empirical techniques in
order to provide portable performance. At present, it provides C and
Fortran77 interfaces to a portably efficient BLAS implementation, as
well as a few routines from LAPACK.

The performance improvements in ATLAS are obtained largely via
compile-time optimizations and tend to be specific to a given hardware
configuration.

  To build a tuned version of atlas for you computer, as root, run:

% cd %{_usrsrc}/ATLAS

% make all install

  The Makefile in this directory uses the same options as the
precompiled atlas packages, and uses the same directory layout.


  You may also prefer to have the files handled by rpm, in which
case you need the source rpm, with which you can run:
% rpmbuild -D "enable_custom_atlas 1" --rebuild atlas-%{version}-%{release}.src.rpm


  NOTES

o It is advisable to ensure cpu throttling is off. To do this:

  % urpmi cpufrequtils
  % cpufreq-set -g performance

o The tests during compilation are heavily dependent on cpu
  load. It is advisable to have as few background processes as
  possible during compilation, otherwise if timing samples are
  too much different, the build will fail, in which case, you
  can run:

  % cd %{_arch}
  % make

  to retry.

o Please also consult the files README and INSTALL.txt.
  Extra documentation is in %{_docdir}/atlas
  Example:
  % cd %{_arch}		# change to architecture build
  % make check		# check if library produces expected results
  % make ptcheck	# check threaded/smp library (if detected/built)
  % make time		# check if library has the expected performance

- Correct a major typo, where the libname major was "upgraded" instead of

- o Restore/reimplement enable_custom_atlas option, as an alternative to
  the "from sources" build, so that files are properly managed by rpm,
  but still built for a single computer.

  any other arch is 32 bits.

* Mon Mar 09 2009 Paulo Andrade <pcpa@mandriva.com.br> 3.8.3-2mdv2009.1

+ rebuild (emptylog)

* Sat Mar 07 2009 Paulo Andrade <pcpa@mandriva.com.br> 3.8.3-1mdv2009.1
+ Revision: 350722
- Bump release and resubmit. ix86 build failed with message:
  EE: gcc: unknown error: PIC register 'bx' clobbered in 'asm'
  (Resubmit to check if same error will again, what could be a bug in
 how atlas build handle the ix86 build computer).
- Update to new upstream release 3.8.3.
  Atlas is a package that requires being compiled in the computer
  where it will be used. To achieve this, a "ready to build" setup
  is available in the main package, and generic precompiled library
  binaries are also available. The default ones are:
  o libatlas-sse2 for ix86
  This requires a Pentium IV class cpu ("modern" ix86 cpus support
  sse3, but Celeron and older Pentium IV class cpus support only sse2).
  o libatlas-x86_64 for x86_64
  Generic x86_64 build.
  Note that the build is dependent on the computer generating the
  packages, and the threaded/smp libraries will only be generated on
  builds on a multi core/cpu computer only.
