调用Ascend CL单算子
前提条件
操作步骤
- 切换到msOpGen脚本install.sh所在目录。
cd ${git_clone_path}/samples/operator/ascendc/0_introduction/1_add_frameworklaunch
- 执行以下命令,生成自定义算子工程,并提供了host侧和kernel侧的算子实现。
bash install.sh -v Ascendxxxyy # xxxyy为用户实际使用的具体芯片类型
- 在${git_clone_path}/samples/operator/ascendc/0_introduction/1_add_frameworklaunch/CustomOp目录下修改CMakePresets.json文件的cacheVariables的配置项,将"Release"修改为"Debug"。
1 2 3 4 5
"cacheVariables": { "CMAKE_BUILD_TYPE": { "type": "STRING", "value": "Debug" },
- 参考算子编译部署完成算子的编译部署。
- 切换到msOpGen脚本install.sh所在目录,并参考README编译单算子调用应用并得到可执行文件execute_add_op。
cd ${git_clone_path}/samples/operator/ascendc/0_introduction/1_add_frameworklaunch/AclNNInvocation
- 导入算子动态加载路径。
将自定义算子工程编译后输出在build_out目录下kernel侧的.o文件路径导入环境变量。
export LAUNCH_KERNEL_PATH=/{path_to_kernel}/kernel_name.o //{path_to_kernel}表示对算子kernel侧实现编译后生成的算子二进制文件*.o所在路径,请根据实际情况进行替换
- 使用msDebug工具加载步骤5中得到的单算子可执行文件execute_add_op。
export LD_LIBRARY_PATH=$ASCEND_HOME_PATH/opp/vendors/customize/op_api/lib:$LD_LIBRARY_PATH cd AclNNInvocation/output msdebug execute_add_op (msdebug) target create "execute_add_op" Current executable set to '/home/AclNNInvocation/output/execute_add_op' (aarch64). (msdebug)
- 断点设置。
b add_custom.cpp:55
- 运行算子程序,等待直到命中断点。
