Gonum LAPACK

A collection of packages to provide LAPACK functionality for the Go programming language (http://golang.org). This provides a partial implementation in native go and a wrapper using cgo to a c-based implementation.

Installation

  go get github.com/gonum/blas

Install OpenBLAS:

  git clone https://github.com/xianyi/OpenBLAS
  cd OpenBLAS
  make

For Windows you can download binary packages for OpenBLAS at http://sourceforge.net/projects/openblas/files/

generate lapack bindings

  cd $GOPATH/src/github.com/gonum/lapack/clapack
  ./genLapack.pl -L/path/to/OpenBLAS -lopenblas

If you want to use the Intel MKL and all of your paths are properly set

  cd $GOPATH/src/github.com/gonum/lapack/clapack
  ./genLapack.pl -lmkl_rt

should work.

Packages

lapack

Defines the LAPACK API based on http://www.netlib.org/lapack/lapacke.html

lapack/clapack

Binding to a C implementation of the lapacke interface (e.g. OpenBLAS or intel MKL)

The linker flags (i.e. path to the BLAS library and library name) might have to be adapted.

The recommended (free) option for good performance on both linux and darwin is OpenBLAS.
