# This PortGroup sets up variants for serial linear algebra (Accelerate/ATLAS/OpenBLAS/OpenBLAS-devel).

#

# Usage:

#

#   PortGroup               linear_algebra 1.0

#

#   If only BLAS and not LAPACK is used, set:

#   linalg.setup blas_only

#   If BLAS/LAPACK are only called from C and not Fortran, then Accelerate can be used

#   directly and vecLibFort is not needed. Set:

#   linalg.setup noveclibfort

#

#   in pre-configure, a line like this may be needed:

#   configure.args-append --with-blas="-L${prefix}/lib ${linalglib}"

#

#   If +threads and +atlas are set, the threaded ATLAS library will be used.

#
