Update of /cvsroot/fink/experimental/jfmertens/main/finkinfo/sci
In directory sc8-pr-cvs17.sourceforge.net:/tmp/cvs-serv858
Added Files:
atlas.info
Log Message:
fixes for uniprocessor machines and for some 64-bit machines
--- NEW FILE: atlas.info ---
Package: atlas
Version: 3.8.0
Revision: 4
Description: Portably optimal linear algebra software
DescDetail: <<
The current version provides a complete BLAS and LAPACK API.
For many operations, ATLAS achieves performance on par
with machine-specific tuned libraries.
Installs also LAPACK's docs and manpages.
Headers: cblas.h clapack.h, plus the atlas headers
Libraries installed:
liblapack.a : The LAPACK routines provided by ATLAS,
plus the rest of LAPACK from netlib.org.
libcblas.a : The ANSI C interface to the BLAS.
libf77blas.a : The Fortran77 interface to the BLAS.
libatlas.a : The main ATLAS library,
providing low-level routines for all interface libs.
Plus the threaded variants libptcblas.a and libptf77blas.a,
and an all-encompassing libatlas.dylib
<<
DescPort: <<
The optimized subset of LAPACK provided by ATLAS is merged
with the full LAPACK from http://www.netlib.org/lapack.
<<
DescUsage: <<
Order is important when linking! Use:
-L%p/lib -llapack -lcblas -lf77blas -latlas

# we first make a shared lib; easier to just write the command here than to
fix lib/Makefile ...

affect timings.
# dylib just made to experiment; not sure this should stay.
# The '-m' flag at the end is dirty trick to get around an "undefined symbol"
for _MAIN__, from -lgfortranbegin;
# _ it swallows the immediately following -lgfortranbegin in the command
transmitted to /usr/bin/libtool ...
# There are no undefined symbols w/o "from ..." in the resulting dylib.
# Is it the -all_load flag that causes the symbol "_main" from
libgfortranbegin.a to be loaded ?
