This post would show how to compile a software suite of linear algebra libraries. Those linear algebra math libraries have been generously used for compiling a mid- and top-level scientific programming such as Fortran, C, and C++.
Their latest versions can be obtained from Netlib Repository: http://www.netlib.org/liblist.html, except ATLAS, which its latest version is available at https://sourceforge.net/projects/math-atlas/files/Stable/ as well as Intel MKL that available only at Intel software suite website.
/home/rangsiman/).See LAPACK
Due to a low-level BLAS software is part of LAPACK, thus I installed only LAPACK. No need to install BLAS separately.
1. Download tarball of LAPACK from this website http://www.netlib.org/lapack/.
2. There will be LAPACK directory called lapack-3.8.0. (the current version of this writing)
3. Move to LAPACK directory
cd lapack-3.8.04. Create make.inc by copying from makefile.inc.example, which is a standard one.
cp make.inc.example make.inc5. Compile and Install using Makefile.
make blaslibmake6. After installation is finished, there must be three libraries in LAPACK directory:
7. Create symbolic link of librefblas.a as libblas.a library.
ln -s librefblas.a libblas.alibblas.a library is required for compiling CBLAS
1. Download the tar.gz. file of CBLAS from BLAS forum on Netlib repository to your Linux
2. Unpack the tar file using following command
tar -xzvf cblas.tgz3. Move to CBLAS directory
cd CBLAS4. Edit PATH of libblas.a and name of CBLAS library at line 26 and 27 in Makefile.in file
vi Makefile.inBLLIB = /home/u31rkk00/lapack-3.8.0/libblas.aCBLIB = ../lib/libcblas.alibblas.a can be obtained from LAPACK directory, where you installed in previous section.
5. Install CBLAS using make
make6. After installation is completed, there must be libcblas.a in CBLAS/lib sub-directory.
1. Download the tar.gz. file of ScaLAPACK from Netlib repository to your Linux
http://www.netlib.org/scalapack/#_software
2. Unpack the tar file using following command
tar -xzvf scalapack-2.0.2.tgz3. Move to ScaLAPACK directory
cd scalapack-2.0.24. Copy SLmake.inc.example to SLmake.inc.
cp SLmake.inc.example SLmake.inc5. Install ScaLAPACK using make
makeThis can take several minutes.
6. After installation is completed, there must be libscalapack.a in ScaLAPACK directory.
However, for alternative ways, if you are using Ubuntu you can use apt to install ScaLAPACK by running:
sudo apt install scalapack-mpi-testor using Red Hat-based OS, run following command instead:
sudo yum install scalapack-mpich2I am going to install ATLAS under my home directory as normal user.
1. Uncompress tarball
mv tlas3.8.3.tar.gz $HOME/cd $HOMEtar -xzvf atlas3.8.3.tar.gz2. Create new directory (either inside or outside ATLAS directory), for example, ATLAS_BUILD
mkdir $HOME/ATLAS_BUILD3. Move to ATLAS_BUILD directory and run configure script (from ATLAS directory) to set up compilation configuration.
cd $HOME/ATLAS_BUILD../ATLAS/configure4. Compile ATLAS using following commands*
makeYou may run compilation using parallel making, says use 8 processors
make -j 8This step can take several minutes/hours (depending on your computer performance).
5. Then check library before install
make checkmake ptcheckmake timeIf having many error occur while checking program, you might ignore those error and proceed next step.
6. Install software
make installWhen installation is finished (with or without error), please check if there is linear algebra library of CBLAS, LAPACK, and ATLAS at $HOME/ATLAS_INSTALL/lib/.
7. Done
There is two error that most users frequently face when install ATLAS using make install command.
1. Cannon create /usr/local/atlas
The default setting of target directory of compiled ATLAS library is /usr/local/atlas. If you are not root or sudo, you cannot install anything on global shared space. Thus you should tell make to install ATLAS under your home directory. Refer to a Makefile file at line 3, for example, change
DESTDIR=/usr/local/atlasto
DESTDIR=/home/rangsiman/ATLAS_INSTALL
2. Cannot find some libraries
cp: cannot stat ‘/home/rangsiman/ATLAS_BUILD/lib/libsatlas.dylib’: No such file or directorymake[1]: [install_lib] Error 1 (ignored)cp /home/u31rkk00/ATLAS_BUILD/lib/libtatlas.dylib /home/u31rkk00/ATLAS_INSTALL/lib/.cp: cannot stat ‘/home/rangsiman/ATLAS_BUILD/lib/libtatlas.dylib’: No such file or directorymake[1]: [install_lib] Error 1 (ignored)cp /home/u31rkk00/ATLAS_BUILD/lib/libsatlas.dll /home/u31rkk00/ATLAS_INSTALL/lib/.cp: cannot stat ‘/home/rangsiman/ATLAS_BUILD/lib/libsatlas.dll’: No such file or directorymake[1]: [install_lib] Error 1 (ignored)cp /home/u31rkk00/ATLAS_BUILD/lib/libtatlas.dll /home/u31rkk00/ATLAS_INSTALL/lib/.cp: cannot stat ‘/home/rangsiman/ATLAS_BUILD/lib/libtatlas.dll’: No such file or directorymake[1]: [install_lib] Error 1 (ignored)cp /home/u31rkk00/ATLAS_BUILD/lib/libsatlas.so /home/u31rkk00/ATLAS_INSTALL/lib/.cp: cannot stat ‘/home/rangsiman/ATLAS_BUILD/lib/libsatlas.so’: No such file or directorymake[1]: [install_lib] Error 1 (ignored)cp /home/u31rkk00/ATLAS_BUILD/lib/libtatlas.so /home/u31rkk00/ATLAS_INSTALL/lib/.cp: cannot stat ‘/home/rangsiman/ATLAS_BUILD/lib/libtatlas.so’: No such file or directorymake[1]: [install_lib] Error 1 (ignored)make[1]: Leaving directory `/home/u7/u31rkk00/ATLAS_BUILD'These error massages can be ignored as long as the static libraries of linear algebra software are build successfully.
All library files should be stored at /home/rangsiman/ATLAS_INSTALL/lib/ directory.
