Py. org. ATLAS is a BLASLAPACK implementation which tuned itself on the machine to provide ideal performances, and often match vendor specific implementations. Unfortunately, building ATLAS is not easy. But, it is getting easier all the time. These instructions show how to build ATLAS and LAPACK from their official distributions. First, download and unpackage the LAPACK distribution from netlib you need these to build a complete version of LAPACK. There are several make. INSTALL directory of the lapack distribution. Copy one of those files to the main directory. For example cp. INSTALLmake. Now, you must edit the make. OPTS and NOOPT lines both contain the flag for compiling position independent code on your platform e. PIC. For example OPTS O2 f. PICNOOPT O0 f. PICNote Make sure that if you build with gfortran that g. PATH when numpy is being built as you need to link with the same compiler that you built lapack with when numpy builds. It will try and find g. Then change to the SRC directory and run make. This will create an lapacklt XXXX. You will need the location of this file to configure atlas. Now, download the latest release of ATLAS these instructions worked on 3. See, for example, https sourceforge. Unpackage the result, change to the directory created, and create a directory to contain the resulting build. This directory should be named appropriate for the platform you can build for multiple platforms from the same SOURCE tree perhaps the source is on a network drive and builds are taking place for multiple platforms. ATLASmkdir. ATLASlt myplatformtype cd. ATLASlt myplatformtype. Faalg f. PIC with netlib lapackpathtolapacklapacklt XXXX. Your atlas libraries should now be in the lib subdirectory of the current directory. You should copy them to some place that you can tell site. If you want to create shared libraries, then you can do that bycdlibmakeshared for sequential librariesmakeptshared for threaded librariesafter changing to the lib directory where the. ATLAS almost painless it will build a complete LAPACK, build it with the right fortran compiler to avoid ABI issues eg gfortranstringwrite, etc., and with the right compiler flags such as it is usable to build numpy and scipy with the f. PIC option. First, download the source rpm included in the ashigabou repository the file atlas version. Then, use the following rpm ivhatlas version. This will NOT install atlas, just uncompress all the necessary files for building the rpm in usrsrcpackages. Before building atlas, you must disable dynamic change of CPU frequency used to decrease battery consumption cpufreq selector gperformance. If this fails telling you no cpufreq support, this is fine. Now, to build the rpm, go into the directory usrsrcpackagesSPEC, and execute. This will build the rpm this can take a long time, even on a powerful machine. What matters is whether atlas has arch defaults for your machine if not, it can take several hours it takes 2 hours and a half on a P4 3. Ghz, but takes 1. If successfull, you will get an installable rpm in usrsrcpackagesRPMSARCH where ARCH can be x. The rpm contains two shared libraries libblas. They are meant to be drop out for the standard BLAS and LAPACK the ones in refblas. To use the atlas libraries, once you installed numpy and scipy, you should tell the OS to use atlas instead of default libraries by using LDLIBRARYPATH. That is, normally, you can use numpy by python cimport numpy as N aN. N. dota, aTo use atlas, you do LDLIBRARYPATHusrlibatlassse. N aN. random. randn1. N. dota, aIf everything is working correctly, you will see that the above script runs much faster with atlas than without I see a ten fold speed increase on my machine.
