-Old debconf information
-------------------------
-
-Certain information regarding atlas has been removed from its debconf
-notes and is now provided here:
-
-Directory layout for atlas libraries
- These atlas packages provide a number of static and shared libraries
- optimized for commonly found hosts. The packages will configure your
- runtime linker to use the version best suited for your system from the
- versions you select for installation. You can, however, override this
- system default by setting the LD_LIBRARY_PATH environment variable for a
- given process at runtime. The first directory in this path containing the
- library sought will be used by the runtime linker. The directory layout
- used by atlas is as follows:
-
- /usr/lib -- reference blas and lapack libraries if installed; atlas
- libraries using only generic code for this general architecture.
-
- /usr/lib/atlas -- atlas-provided blas and lapack libs using only generic
- code for this general architecture.
-
- /usr/lib/<flag> -- atlas libraries using cpu extension instructions which
- require the running cpu to have capability <flag>, as reported in
- /proc/cpuinfo. E.g. 'sse' for SSE1, '3dnow' for 3dnow, etc.
-
- /usr/lib/<flag>/atlas -- atlas-provided blas and lapack libraries using
- cpu extensions as described above.
-
-Using atlas-provided blas/lapack instead of reference
-
- Atlas provides binary compatible blas and lapack shared libraries which
- can transparently be used instead of the reference implementations (i.e.
- packages blas and lapack), thereby significantly enhancing the performance
- of several software packages using BLAS and LAPACK routines (e.g. R,
- octave). This package has configured ld.so.conf to load the
- atlas-provided versions of these libraries instead of the reference
- versions which may or may not be installed.
-
-Sharing /usr via nfs
-
- Please note that if you export /usr via nfs, the runtime linker
- configuration performed here will not affect the nfs clients. These atlas
- packages can therefore be installed on an nfs server serving a mixed
- subarchitecture network, with each client running its own optimal version
- of the libraries. To achieve this, please configure /etc/ld.so.conf.d/atlas.conf on
- the clients appropriately given the directory layout specified previously,
- and then run ldconfig.
-
-
-
-Important note on ISAEXT
-------------------------
-
-On three architectures, sparc, alpha, and hppa, the desired isa
-extension in any custom build as described below is not selected via
-the ISAEXT environment variable, but rather by the MACH environment
-variable. This is due to the way upstream classifies and probes for
-extensions, and is intended to keep the patch to config.c small. If
-desired, simply replace the ISAEXT settings described below with MACH
-settings from this table on these platforms:
-
-arch isa extension desired MACH variable setting
-==== ===================== =====================
-sparc v9 'UltraSparc II'
-hppa 2.0 (abi) 'PA-RISC 2.0'
-alpha ev6 'EV6'
-
-What's new in 3.6.0
--------------------
-
-The soname for the blas, lapack, and atlas shared libraries has been
-incremented due to a (minor) incompatibility introduced in the cblas
-API when a long outstanding error had been corrected.
-
-The changes can be summarized as follows:
-
- 1) cblas_i?amax routines now return a value i such that 0 <= i < N,
- where N is the length of the array.
-
- 2) certain cblas error codes are now correctly switched or
- interchanged in the case of row major matrices.
-
- 3) the symbol RowMajorStrg is not longer exported by the
- library.
-
-Packages for both the old soname (2) and the new are being
-simultaneously provided to ease in the transition.
-
-In addition, three new environment variables have been added for use
-in building custom packages:
-
-Variable Default Notes
--------- ------- -----
-CACHE variable This will default to a value determined from
- /proc/cpuinfo (L2) if available, and the atlas
- supplied default otherwise. This serves as
- an upperbound for the timing and searching
- algorithms, so that knowing the true value
- is smaller than the default will speed up
- the tiing process.
-
-BIT 1 For use on Opteron systems, 1 indicates a 32bit
- build, 2 indicates 64bit
-
-TDNCOMP n On certain AMD processors, atlas can use the
- non-IEEE compliant 3DNow2 instructions for
- computational operations. As this can lead to
- inaccuracy should the operation overflow (as
- 3DNow2 provides no NaN nor Inf results), this
- is turned off by default as in upstream atlas.
- This behavior differs from that in 3.2.1. For
- the Debian pre-supplied 3dnow build, this variable
- has been set to y and a debconf warning attached,
- as otherwise the build would be close to atlas3-base
- and could therefore be covered by this package
- to the resolution attempted by the pre-supplied
- builds. Unless this variable is changed when building
- a custom package, unlike the pre-supplied 3dnow build,
- 3DNow2 instructions will only be used for
- non-computational operations (like prefetch).
-
-What's new in 3.2.1
--------------------
-
-As of version 3.2.1, atlas provides kernels optimized to use processor
-extension instructions, such as 3dNOW and SSE. While this is a great
-benefit in terms of performance, it introduces several difficulties in
-packaging for a distribution such as Debian.
-
-The first difficulty, which this package attempts to resolve, is that
-atlas by its very nature (Automatically Tuned Linear Algebra
-Subroutines) cannot adequately cross-compile without compile-time
-access to the target subarch in question. As Debian currently cannot
-ensure that a given package will be auto-built on a machine of a
-particular subarch, this would normally entail that the atlas package
-configure itself for the lowest common denominator. In this
-particular case, as the performance differences are so great, such a
-policy would essentially result in the vast majority of users
-recompiling the package for themselves, making a binary package at all
-of questionable use.
-
-This package attempts to strike a middle ground. Sample builds have
-been recorded and collected on a variety of representative subarch
-machines. The default build process reruns these records at compile
-time without ever executing any generated code on the compiling
-machine. A procedure for customizing the atlas libraries to the
-machine of installation is provided via the 'custom' target of
-debian/rules, and is described more thoroughly below.
-
-The second difficulty regards the location of these libraries. The
-default build puts only generic code which can run on all systems of
-the general architecture in /usr/lib. Subarch specific code is placed
-in /usr/lib/<cpu flag>, where the flag refers to the capability as
-listed in /proc/cpuinfo required to execute the library. There was
-some discussion that ldso might automatically search these directories
-first on the run-time machine, making the installation completely
-transparent to the user, and even allowing sharing /usr across NFS
-with all participating machines running their own optimal code. So
-far, however, ldso only searches ix86 and ix86/mmx subdirs, which does
-not provide sufficient resolution.
-
-The solution at present therefore is for the user to either add the
-appropriate paths to /etc/ld.so.conf.d/atlas.conf on each machine accessing the
-libraries, or to set the environment variable LD_LIBRARY_PATH at
-runtime. For example, in a setup where atlas2-{base,sse,sse2,3dnow} are
-all installed and /usr is NFS exported, the user should either
-
- 1. a) add /usr/lib/3dnow to /etc/ld.so.conf.d/atlas.conf all participating
- 3dnow machines, and then run ldconfig
- b) add /usr/lib/sse to /etc/ld.so.conf.d/atlas.conf all participating
- sse machines, and then run ldconfig
- c) add /usr/lib/sse2 to /etc/ld.so.conf.d/atlas.conf all participating
- sse2 machines, and then run ldconfig
-
-or
-
- 2. Add this or equivalent to $(HOME)/.profile or /etc/profile:
- for i in sse sse2 3dnow ; do \
- grep ^flags /proc/cpuinfo | grep "\<$i\>" > /dev/null && \
- export LD_LIBRARY_PATH=/usr/lib/$i:$LD_LIBRARY_PATH \
- done
-
-The current versions of the atlas packages will perform the above
-modifications on /etc/ld.so.conf.d/atlas.conf automatically, but only, of course,
-on the machine of installation. Manual treatment is still required
-for any clients accessing the libraries across NFS.
-
-If you are a 'porter', and want to submit a build record for a new
-binary subarch package, please do the following:
-
- 1. apt-get source atlas
- 2. cd atlas-3.2.1
- 3. (ensure that all necessary tools for building are
- available, as listed in 'grep Build-Depends
- debian/control')
- 4a. 'fakeroot debian/rules build_record' (probed isa
- extension) or
- 4b. 'ISAEXT= fakeroot debian/rules build_record' (no isa
- extension) or
- 4c. 'ISAEXT=??? fakeroot debian/rules build_record' (specified
- isa extension)
- 5. If 4. terminates successfully, email me the emitted and
- uuencoded build record, between the output lines "Build
- record" and "done"
-
-
-Building Customized Atlas Packages
-==================================
-
-A user wishing to run the full upstream build process, customizing
-thereby the library to her particular machine, should unpack the
-source with 'apt-get source atlas', ensure all build-dependencies are
-satisfied as listed by 'grep Build-Depends debian/control', and then
-'fakeroot debian/rules custom' in the source directory. This will
-create the appropriate isa extension atlas2-? and atlas2-?-dev
-packages tailored to the compiling machine which the user can then
-install. If a custom 'base' install is desired, i.e. ignoring any
-probed available isa extensions, replace the above with 'ISAEXT=
-fakeroot debian/rules custom'. Finally, if you wish to ignore any
-upstream defaults atlas has provided for your machine, thereby
-selecting the most thorough and time-consuming customization of the
-atlas libraries to your system, you can execute 'DEFAULTS=n fakeroot
-debian/rules custom.' The DEFAULTS and ISAEXT variables can be
-combined. Whenever one wishes to change the ISAEXT variable from a
-previous custom build, however, a 'fakeroot debian/rules clean' must
-be executed first.
-
-The atlas-doc and atlas2-headers packages (the latter which is a
-dependency of atlas2-?-dev) can be created with 'fakeroot debian/rules
-binary-indep'.
-

-
-3.0 README
-----------
-
-
-The atlas packages provide both atlas libraries in /usr/lib
-(libatlas*,libf77blas*,libcblas*,liblapack_atlas*), and full,
-atlas-optimized, binary-compatible blas/lapack libraries in
-/usr/lib/atlas (libblas*,liblapack*). The i386 versions of these
-binary libraries are the result of running the atlas tuning routines
-on an Intel PII 350. While these binaries seem to offer good
-performance on a variety of Intel hardware, the end user may wish to
-customize the atlas libraries to her/his own system. This is done by
-rebuilding the Debian atlas packages from their Debian sources on the
-machine in question, and installing the resulting binary packages.
-
-The atlas-optimized blas libraries were built purely from atlas source
-(a merge of libatlas and libf77blas), as atlas now provides full blas
-support as of version 3.0. The atlas-optimized lapack libraries were
-built from the reference implementation sources on netlib (via the
-Debian lapack package), with optimized modules in the lapack_atlas
-library replacing the reference version where possible. Atlas does
-not yet offer optimized versions of all lapack routines. Both
-libraries should be a completely binary compatible with their netlib
-reference implementations. Any program linking against a shared
-libblas.so.2 and/or liblapack.so.2 can use the atlas-optimized
-versions without recompiling by setting the environment variable
-LD_LIBRARY_PATH to /usr/lib/atlas. Alternately, one can force the
-loading of the atlas modules under any environment by relinking
-executables and replacing -lblas with -lf77blas -latlas and -llapack
-with -llapack_atlas -lcblas -lf77blas on the command line.
-
-Please note that the performance of some Atlas routines varies
-significantly with the LDA parameter. Large powers of two (of the
-order of magnitude of the system page size, e.g. 1024, 2048 ... floats
-on Linux x86) are particularly bad, but other multiples of small
-powers of two (e.g. 4,8,16) are generally good.
