### 1. 定义ProtoMaker类
矩阵乘的公式:$Out = X * Y$, 可见该计算由两个输入,一个输出组成。首先定义`ProtoMaker`来描述该Op的输入、输出及注释:

[`MulOpMaker`](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/mul_op.cc#L43)继承自`framework::OpProtoAndCheckerMaker`,构造函数包括2个参数
- `framework::OpProto` : 前者存储Op的输入输出和参数属性,将用于Python API接口的生成。
- `framework::OpAttrChecker` :后者用于检查参数属性的合法性。
构造函数里通过`AddInput`添加输入参数,通过`AddOutput`添加输出参数,通过`AddComment`添加该Op的注释,这些函数会将对应内容添加到`OpProto`中。
`MulOp`中添加两个输入`X``Y`,添加了一个输出`Out`,并解释了各自含义,该命名尽可能的规范。

`MulKernel`继承自`framework::OpKernel`,带有模板参数:
- `typename Place`: 表示设备类型,不同设备(CPU、GPU)共享同一个Kernel时,需加该模板参数,不共享则不加,一个不共享的例子是[`OnehotCrossEntropyOpKernel`](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/cross_entropy_op.h#L43)
- `typename T` : 表示数据类型,如`float`, `double`等。
`MulKernel`需要重写`Compute`接口,该接口参数为`const framework::ExecutionContext& context`, `ExecutionContext`相比`InferShapeContext`增加了设备类型,同样可获取到输入输出和属性参数,`Compute`函数里写具体实现时。
注意,不同设备(CPU、GPU)共享一个Op定义,是否则共享同一个`OpKernel`,取决于`Compute`调用的函数是否支持不同设备。`MulOp`的CPU、GPU实现共享同一个`Kernel``OpKernel`不共享的例子可以参考[`OnehotCrossEntropyOpKernel`](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/cross_entropy_op.h#L43)
为了使得`OpKernel`的计算过程书写较为简单,CPU、GPU的代码可以复用,我们通常借助Eigen unsupported Tensor模块来实现。关于在paddle中如何使用Eigen库,请参考对应的使用[文档](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/howto/dev/use_eigen_cn.md)
到此前向Op实现完成,需要在`.cc`文件中注册该op和kernel。反向Op类的定义和Kernel定义与前向Op类似,这里不再重复。但注意,反向Op没有`ProtoMaker`
### 4. 注册Operator
`.cc`文件中注册前向、反向Op类,注册CPU Kernel。
```c++
```cpp
namespace ops = paddle::operators;
REGISTER_OP(mul, ops::MulOp, ops::MulOpMaker, mul_grad, ops::MulOpGrad);
REGISTER_OP_CPU_KERNEL(mul, ops::MulKernel<paddle::platform::CPUPlace, float>);
REGISTER_OP_CPU_KERNEL(mul_grad,
ops::MulGradKernel<paddle::platform::CPUPlace, float>);
```
- `REGISTER_OP` : 注册`ops::MulOp`类,类型名为`mul`,该类的`ProtoMaker``ops::MulOpMaker`,注册`ops::MulOpGrad`,类型名为`mul_grad`
- `REGISTER_OP_WITHOUT_GRADIENT` : 用于注册没有反向的Op。
- `REGISTER_OP_CPU_KERNEL` :注册`ops::MulKernel`类,并特化模板参数为`paddle::platform::CPUPlace``float`类型,同理,注册`ops::MulKernel`类。
`.cu`文件中注册GPU Kernel。请注意,如果GPU Kernel的实现是基于Eigen unsupported模块,那么在 `.cu`的最前面请加上宏定义 `#define EIGEN_USE_GPU`

### 5. 编译
[paddle/operators/CMakeLists.txt](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/CMakeLists.txt)文件中添加编译。
```
op_library(mul_op SRCS mul_op.cc mul_op.cu DEPS math_function)
```
下面命令可以编译:
```
make mul_op
```
- 简单**无特殊依赖**的OP无需修改CMakeList.txt文件。[paddle/operators/CMakeLists.txt](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/CMakeLists.txt) 会自动将 `paddle/operators` 目录下新增的 `*_op.cc` 文件加入编译。
- 较为复杂、**有额外依赖** 的operator仍需要修改[paddle/operators/CMakeLists.txt](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/operators/CMakeLists.txt)。如,`mul_op` 依赖 `math_function`,需要在`CMakeLists.txt`中添加如下内容:
```
op_library(mul_op SRCS mul_op.cc mul_op.cu DEPS math_function) +
```
- 运行下面命令可以进行编译:
```
make mul_op
```
## 绑定Python

[`paddle/pybind/pybind.cc
- 绑定Python
在 [`paddle/pybind/pybind.cc
`](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/pybind/pybind.cc)文件中添加该类:
```
USE_OP(mul);
```
如果只实现了CPU版本,则使用`USE_CPU_ONLY_OP`:
```
USE_CPU_ONLY_OP(gather);
```
如果OP不带Kernel,则使用`USE_NO_KENREL_OP`:
```
USE_NO_KENREL_OP(recurrent);
```
使用`USE_OP`告知编译器需要链接该Op的目标文件,具体解释参考[代码注释](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/framework/op_registry.h#L81)。
- 生成库
[`paddle/pybind/CMakeLists.txt`](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/pybind/CMakeLists.txt)文件添加类到`DEPS`中,使得该Op可以链接到生成的lib库中。
```
if(WITH_PYTHON)
cc_library(paddle_pybind SHARED
SRCS pybind.cc
DEPS pybind python backward
mul_op
minus_op)
endif(WITH_PYTHON)
```
无需修改 [`paddle/pybind/CMakeLists.txt`](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/pybind/CMakeLists.txt)文件,`paddle/operators` 目录下新增的 `*_op.cc` 文件会自动被添加链接到生成的lib库中。
## 实现单元测试
单测包括对比前向Op不同设备(CPU、GPU)的实现、对比反向OP不同设备(CPU、GPU)的实现、反向Op的梯度测试。下面介绍介绍[`MulOp`的单测](https://github.com/PaddlePaddle/Paddle/blob/develop/python/paddle/v2/framework/tests/test_mul_op.py)。
### 前向Operator单
### 前向Operator单元测试
前向Op单测继承自`unittest.TestCase`,并定义元类`__metaclass__ = OpTestMeta`,具体单测流程在`OpTestMeta`里完成。需在`setUp`函数定义输入输出和属性参数,以及Python对比的输出值。

- `self.inputs` : 定义输入,类型为Numpy.array,并初始化。
- `self.outputs` : 定义输出,并得到Python结算结果。

The input of softmax operator is a 2-D tensor with shape N x K (N is the
batch_size, K is the dimension of input feature). The output tensor has the
same shape as the input tensor.
For each row of the input tensor, the softmax operator squashes the
K-dimensional vector of arbitrary real values to a K-dimensional vector of real
values in the range [0, 1] that add up to 1. Specifically, it computes the
exponential of the given dimension and the sum of exponential values of all
the other dimensions in the K-dimensional vector input. Then the ratio of the
exponential of the given dimension and the sum of exponential values of all
the other dimensions is the output of the softmax operator.
For each row `i` and each column `j` in X, we have:
Y[i, j] = exp(X[i, j]) / sum_j(exp(X[i, j]))
)DOC");
