源码编译llama.cpp 、ggml 后端启用自定义BLAS加速

源码编译llama.cpp 、ggml 后端启用自定义BLAS加速

我在llama.cpp 官网上提交了我的解决方案：How to setup OpenBlas on windows? #625

GGML 官网 https://github.com/ggerganov/ggml/issues/959

windows on arm 编译 llama.cpp 、ggml 后端启用自定义BLAS加速

我这以编译 windows on arm 的 llama.cpp 、ggml 为例子，其它情况同样可以

参考我的文章 《源码编译 openblas for windows on arm》 我用了自己编译的这个 openblas

原理 blas 加速是通过编译ggml提供的

所以修改llama.cpp/ggml/src/CMakeLists.txt ，在这一行代码if (GGML_BLAS) 前面添加以下代码：

自定义编译blas:

# add custom blas
if (CUSTOM_BLAS)
	set(BLAS_ROOT "C:/workspace/program/openblas")
	set(BLAS_INCLUDE_DIRS
        "${BLAS_ROOT}/include/"
        "${BLAS_ROOT}/include/openblas"
    )
	set(BLAS_LIBRARIES "${BLAS_ROOT}/lib/openblas.lib")
	list(APPEND GGML_CDEF_PUBLIC GGML_USE_BLAS)
	
	set(GGML_HEADERS_BLAS ../include/ggml-blas.h)
	set(GGML_SOURCES_BLAS ggml-blas.cpp)
	
	set(GGML_EXTRA_LIBS     ${GGML_EXTRA_LIBS}     ${BLAS_LIBRARIES})
	set(GGML_EXTRA_INCLUDES ${GGML_EXTRA_INCLUDES} ${BLAS_INCLUDE_DIRS})
endif()

然后编译时指定 CUSTOM_BLAS=ON:

cmake -B build -DGGML_BLAS=OFF  -DCUSTOM_BLAS=ON
cmake --build build --config Release
