# Uncomment one of the 4 BLAS/Lapack implementation options
|
|
# below. They are sorted # from fastest to slowest (in our
|
|
# experiments).
|
|
##########################################################################
|
|
|
|
#
|
|
# 1. Intel MKL
|
|
#
|
|
# This is the fastest BLAS implementation we tested. Unfortunately it
|
|
# is not open-source and determining the correct linking flags is a
|
|
# nightmare. See
|
|
#
|
|
# https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor
|
|
#
|
|
# The latest tested version is MKL 2017.0.098 (2017 Initial Release) and can
|
|
# be downloaded here:
|
|
#
|
|
# https://registrationcenter.intel.com/en/forms/?productid=2558&licensetype=2
|
|
#
|
|
# The following settings are working if MKL is installed on its default folder:
|
|
#
|
|
# MKLROOT = /opt/intel/compilers_and_libraries/linux/mkl/
|
|
#
|
|
# LDFLAGS += -Wl,--no-as-needed -L$(MKLROOT)/lib/intel64
|
|
# LIBS += -lmkl_intel_ilp64 -lmkl_core -lmkl_gnu_thread -ldl -lpthread
|
|
#
|
|
# CPPFLAGS += -DFINTEGER=long
|
|
#
|
|
# You may have to set the LD_LIBRARY_PATH=$MKLROOT/lib/intel64 at runtime.
|
|
|
|
#
|
|
# 2. Openblas
|
|
#
|
|
# The library contains both BLAS and Lapack. Install with brew install OpenBLAS
|
|
#
|
|
# CPPFLAGS += -DFINTEGER=int
|
|
# LIBS += /usr/local/opt/openblas/lib/libblas.dylib
|
|
#
|
|
|
|
#
|
|
# 3. Apple's framework accelerate
|
|
#
|
|
# This has the advantage that it does not require to install anything,
|
|
# as it is provided by default on the mac. It is not very fast, though.
|
|
#
|
|
|
|
CPPFLAGS += -DFINTEGER=int
|
|
LIBS += -framework Accelerate
