Introduction to ATLAS

BLAS are Basic Linear Algebra Subprograms written in Fortran. There are Level 1 (scalar and vector operations), Level 2 (scalar-matrix operations) and Level 3 (matrix-matrix operations) subprograms. ATLAS (Automatically Tuned Linear Algebra Software) will provide C and FORTRAN interfaces to a BLAS implementation optimized for a specific machine architecture. The ideal source of BLAS and LAPACK libraries are those provided by the microprocesor vendor such as AMD's ACML. However, these are not provided under a license that allows re-distribution without written consent from the vendor.

Non-Multilib

First, build the LAPACK libraries, then compile the package: 

mkdir build &&
cd build &&
../configure --prefix=/usr \
--with-netlib-lapack=$PWD/../../lapack-3.1.1/lapack_LINUX.a \
-Fa alg -fPIC &&
sed -i "/RANLIB/s/echo/ranlib/" Make.inc &&
make &&
cd lib &&
make shared &&
make ptshared &&
cd ..

Install the package: 

 make install &&
 cp -v lib/*so /usr/lib

Multilib

32Bit

First, build the LAPACK libraries, then compile the package: 

mkdir build &&
cd build &&
CC="gcc ${BUILD32}" ../configure --prefix=/usr \
--with-netlib-lapack=$PWD/../../lapack-3.1.1/lapack_LINUX.a \
-Fa alg -fPIC &&
sed -i "/RANLIB/s/echo/ranlib/" Make.inc &&
make &&
cd lib &&
make shared &&
make ptshared &&
cd ..

Install the package: 

 make install &&
 cp -v lib/*so /usr/lib

N32

First, build the LAPACK libraries, then compile the package: 

mkdir build &&
cd build &&
CC="gcc ${BUILDN32}" ../configure \
--prefix=/usr --libdir=/usr/lib32 \
--with-netlib-lapack=$PWD/../../lapack-3.1.1/lapack_LINUX.a \
-Fa alg -fPIC &&
sed -i "/RANLIB/s/echo/ranlib/" Make.inc &&
make &&
cd lib &&
make shared &&
make ptshared &&
cd ..

Install the package: 

 make install &&
 cp -v lib/*so /usr/lib32

64Bit

First, build the LAPACK libraries, then compile the package: 

mkdir build &&
cd build &&
CC="gcc ${BUILD64}" ../configure \
--prefix=/usr --libdir=/usr/lib64 \
--with-netlib-lapack=$PWD/../../lapack-3.1.1/lapack_LINUX.a \
-Fa alg -fPIC &&
sed -i "/RANLIB/s/echo/ranlib/" Make.inc &&
make &&
cd lib &&
make shared &&
make ptshared &&
cd ..

Install the package: 

 make install &&
 cp -v lib/*so /usr/lib64
