# This library's version
VERSION = 0.2.7

# 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.
# CC = x86_64-w64-mingw32-gcc
# FC = x86_64-w64-mingw32-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.
# 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 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 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

# 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

# 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 parallel make.
# NO_PARALLEL_MAKE = 1

# 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

# Run testcases in utest/ . When you enable UTEST_CHECK, it would enable
# SANITY_CHECK to compare the result with reference BLAS.
# UTEST_CHECK = 1

# The installation directory.
# PREFIX = /opt/OpenBLAS

# Common Optimization Flag; 
# The default -O2 is enough.
# COMMON_OPT = -O2

# Profiling flags
COMMON_PROF = -pg

# Build Debug version
# DEBUG = 1
