OpenBLAS can be built for multiple targets with runtime detection of the target cpu by specifiying DYNAMIC_ARCH=1 in le, on the gmake command line or as -DDYNAMIC_ARCH=TRUE in cmake.įor x86_64, the list of targets this activates contains Prescott, Core2, Nehalem, Barcelona, Sandybridge, Bulldozer, Piledriver, Steamroller, Excavator, Haswell, Zen, SkylakeX.

Set CC and FC to point to the cross toolchains, and set HOSTCC to your host C compiler. To the source tree and any build options you plan to set.

To set a specific target CPU, use make TARGET=xxx, e.g. Simply invoking make (or gmake on BSD) will detect the CPU automatically. A Fortran compiler (optional, for LAPACK).Dependenciesīuilding OpenBLAS requires the following to be installed: Most can also be given directly on the make or cmake command line. Sure to use the develop branch - master is several years out of date due to a change of maintainership.)īuildtime parameters can be chosen in le, see there for a short description of each option.

We provide official binary packages for the following platform: Gilbert Strang on either MIT OpenCourseWare or Youtube may be helpful. If you are looking for a general primer or refresher on Linear Algebra, the set of sixĢ0-minute lecture videos by Prof. On that site you will likewise find documentation for the reference implementation of the higher-level library LAPACK - the Linear Algebra Package that comes included with OpenBLAS. įor a general introduction to the BLAS routines, please refer to the extensive documentation of their reference implementation hosted at netlib: Please read the documentation on the OpenBLAS wiki pages. OpenBLAS is an optimized BLAS (Basic Linear Algebra Subprograms) library based on GotoBLAS2 1.13 BSD version.
