#
# Beginning of user configuration
#
# This library's version
VERSION = 0.2.20.dev
# If you set the suffix, the library name will be libopenblas_$(LIBNAMESUFFIX).a
# and libopenblas_$(LIBNAMESUFFIX).so. Meanwhile, the soname in shared library
# is libopenblas_$(LIBNAMESUFFIX).so.0.
# LIBNAMESUFFIX = omp
# You can specify the target architecture, otherwise it's
# automatically detected.
# TARGET = PENRYN
# If you want to support multiple architecture in one binary
# DYNAMIC_ARCH = 1
# C compiler including binary type(32bit / 64bit). Default is gcc.
# Don't use Intel Compiler or PGI, it won't generate right codes as I expect.
# CC = gcc
# Fortran compiler. Default is g77.
# FC = gfortran
# Even you can specify cross compiler. Meanwhile, please set HOSTCC.
# cross compiler for Windows
# CC = x86_64-w64-mingw32-gcc
# FC = x86_64-w64-mingw32-gfortran
# cross compiler for 32bit ARM
# CC = arm-linux-gnueabihf-gcc
# FC = arm-linux-gnueabihf-gfortran
# cross compiler for 64bit ARM
# CC = aarch64-linux-gnu-gcc
# FC = aarch64-linux-gnu-gfortran
# If you use the cross compiler, please set this host compiler.
# HOSTCC = gcc
# If you need 32bit binary, define BINARY=32, otherwise define BINARY=64
# BINARY=64
# About threaded BLAS. It will be automatically detected if you don't
# specify it.
# For force setting for single threaded, specify USE_THREAD = 0
# For force setting for multi threaded, specify USE_THREAD = 1
# USE_THREAD = 0
# If you're going to use this library with OpenMP, please comment it in.
# This flag is always set for POWER8. Don't modify the flag
# USE_OPENMP = 1
# You can define maximum number of threads. Basically it should be
# less than actual number of cores. If you don't specify one, it's
# automatically detected by the the script.
# NUM_THREADS = 24
# if you don't need to install the static library, please comment it in.
# NO_STATIC = 1
# if you don't need generate the shared library, please comment it in.
# NO_SHARED = 1
# If you don't need CBLAS interface, please comment it in.
# NO_CBLAS = 1
# If you only want CBLAS interface without installing Fortran compiler,
# please comment it in.
# ONLY_CBLAS = 1
# If you don't need LAPACK, please comment it in.
# If you set NO_LAPACK=1, the library automatically sets NO_LAPACKE=1.
# NO_LAPACK = 1
# If you don't need LAPACKE (C Interface to LAPACK), please comment it in.
# NO_LAPACKE = 1
# Build LAPACK Deprecated functions since LAPACK 3.6.0
BUILD_LAPACK_DEPRECATED = 1
# Build RecursiveLAPACK on top of LAPACK
# BUILD_RELAPACK = 1
# If you want to use legacy threaded Level 3 implementation.
# USE_SIMPLE_THREADED_LEVEL3 = 1
# If you want to drive whole 64bit region by BLAS. Not all Fortran
# compiler supports this. It's safe to keep comment it out if you
# are not sure(equivalent to "-i8" option).
# INTERFACE64 = 1
# Unfortunately most of kernel won't give us high quality buffer.
# BLAS tries to find the best region before entering main function,
# but it will consume time. If you don't like it, you can disable one.
NO_WARMUP = 1
# If you want to disable CPU/Memory affinity on Linux.
#NO_AFFINITY = 1
# if you are compiling for Linux and you have more than 16 numa nodes or more than 256 cpus
# BIGNUMA = 1
# Don't use AVX kernel on Sandy Bridge. It is compatible with old compilers
# and OS. However, the performance is low.
# NO_AVX = 1
# Don't use Haswell optimizations if binutils is too old (e.g. RHEL6)
# NO_AVX2 = 1
# Don't use parallel make.
# NO_PARALLEL_MAKE = 1
# Force number of make jobs. The default is the number of logical CPU of the host.
# This is particularly useful when using distcc.
# A negative value will disable adding a -j flag to make, allowing to use a parent
# make -j value. This is useful to call OpenBLAS make from an other project
# makefile
# MAKE_NB_JOBS = 2
# If you would like to know minute performance report of GotoBLAS.
# FUNCTION_PROFILE = 1
# Support for IEEE quad precision(it's *real* REAL*16)( under testing)
# QUAD_PRECISION = 1
# Theads are still working for a while after finishing BLAS operation
# to reduce thread activate/deactivate overhead. You can determine
# time out to improve performance. This number should be from 4 to 30
# which corresponds to (1 << n) cycles. For example, if you set to 26,
# thread will be running for (1 << 26) cycles(about 25ms on 3.0GHz
# system). Also you can control this mumber by THREAD_TIMEOUT
# CCOMMON_OPT += -DTHREAD_TIMEOUT=26
# Using special device driver for mapping physically contigous memory
# to the user space. If bigphysarea is enabled, it will use it.
# DEVICEDRIVER_ALLOCATION = 1
# If you need to synchronize FP CSR between threads (for x86/x86_64 only).
# CONSISTENT_FPCSR = 1
# If any gemm arguement m, n or k is less or equal this threshold, gemm will be execute
# with single thread. You can use this flag to avoid the overhead of multi-threading
# in small matrix sizes. The default value is 4.
# GEMM_MULTITHREAD_THRESHOLD = 4
# If you need santy check by comparing reference BLAS. It'll be very
# slow (Not implemented yet).
# SANITY_CHECK = 1
# The installation directory.
# PREFIX = /opt/OpenBLAS
# Common Optimization Flag;
# The default -O2 is enough.
# Flags for POWER8 are defined in Makefile.power. Don't modify COMMON_OPT
# COMMON_OPT = -O2
# gfortran option for LAPACK
# enable this flag only on 64bit Linux and if you need a thread safe lapack library
# Flags for POWER8 are defined in Makefile.power. Don't modify FCOMMON_OPT
# FCOMMON_OPT = -frecursive
# Profiling flags
COMMON_PROF = -pg
# Build Debug version
# DEBUG = 1
# Set maximum stack allocation.
# The default value is 2048. 0 disable stack allocation a may reduce GER and GEMV
# performance. For details, https://github.com/xianyi/OpenBLAS/pull/482
#
# MAX_STACK_ALLOC = 0
# Add a prefix or suffix to all exported symbol names in the shared library.
# Avoid conflicts with other BLAS libraries, especially when using
# 64 bit integer interfaces in OpenBLAS.
# For details, https://github.com/xianyi/OpenBLAS/pull/459
#
# The same prefix and suffix are also added to the library name,
# i.e. you get lib$(SYMBOLPREFIX)openblas$(SYMBOLSUFFIX) rather than libopenblas
#
# SYMBOLPREFIX=
# SYMBOLSUFFIX=
#
# End of user configuration
