From c7a5c3e0bba2ac3d197b219d21527863308b75dd Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Fri, 18 Jun 2021 18:07:21 +0200 Subject: gnu: petsc: Link against OpenBLAS rather than LAPACK. OpenBLAS performs better than LAPACK, the reference implementation. This is also consistent with the choice of BLAS/LAPACK implementations made in most other packages. * gnu/packages/maths.scm (petsc)[inputs]: Replace LAPACK by OPENBLAS. [arguments]: Pass "--with-openblas=1". --- gnu/packages/maths.scm | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'gnu') diff --git a/gnu/packages/maths.scm b/gnu/packages/maths.scm index 84540d5ffe..dc18536aa7 100644 --- a/gnu/packages/maths.scm +++ b/gnu/packages/maths.scm @@ -2417,7 +2417,7 @@ September 2004}") `(("python" ,python-2))) (inputs `(("gfortran" ,gfortran) - ("lapack" ,lapack) + ("openblas" ,openblas) ("superlu" ,superlu) ;; leaving out hdf5 and fftw, as petsc expects them to be built with mpi ;; leaving out opengl, as configuration seems to only be for mac @@ -2428,6 +2428,7 @@ September 2004}") #:configure-flags `("--with-mpi=0" "--with-openmp=1" + "--with-openblas=1" "--with-superlu=1") #:make-flags ;; Honor (parallel-job-count) for build.
