+# JIT Kernel
+
+JIT(Just In Time) Kernel contains actually generated code and some other implemenations with the same logic.
+Each implementations has its own condition to use, defined in `UseMe`.
+They are combined together to get the best performance of one single independent function.
+They could be some very simple functions like vector multiply, or some complicated functions like LSTM.
+And they can be composed with some other exited jit kernels to build up a complex function. 
+Currently it's only supported on CPU yet.

+
+All basical definations of jit kernels are addressed in `paddle/fluid/operators/jit` including these three key folders `refer`, `gen`, `more`. There is only one unique name for each kernel while may have seraval implementations with same functionality.
+
+- `refer`: Each kernel must have one reference implementation on CPU, and it should only focus on the correctness and should not depends on any third-party libraries.
+- `gen`: The code generated should be kept here. They should be designed focusing on the best performance, which depends on Xbyak.
+- `more`: All other implementations should be kept in this folder with one directory corresponding to one library kind or method kind, such as mkl, mkldnn, openblas or intrinsic code. Each implementation should have it advantage. 
+
+## How to use
+
+One simple function `jit::Get`, which is very easy to use, is supported to get the kernel.
+It can automatically return the expected function with best performance under the given attributes. 
+All kernels are inlcuded in `paddle/fluid/operators/jit/kernels.h`, you can only include this one header to get all the registered kernels.
+
+## Solid Test
+
+- Unit Test
+    All functions should be compared with the corresponding reference functions, including data tyep `float` and `double`.
+- Benchmark
+    All functions should be tested, and make sure the `jit::Get` function obtain the best performance with all attributes.
+
+# How to add new kernel
+
+## Required
+
+1. Add `your_key` at `KernelType`.
+2. Add reference function of `your_key`. 
+Note:
+    - this should be run on CPU and do not depend on any third-party.
+    - Add `USE_JITKERNEL_REFER(your_key)` in `refer/CmakeLists.txt` to make sure this code can be used.
+3. Add unit test in `test.cc`, and verfiy at least `float` and `double`.
+Test more data type for some special functions if necessary, for example `int8`.
+4. Add functions in `benchmark.cc` to test all function of same `KernelType`. Make sure `jit::Get` always get the best one.
+
+## Optional
+
+Add more implementations of `your_kery` for performance enhancement.
+
+1. Add functions based on generated code in `gen`. It should be derived from `JitCode` and should have corepsonding creator from `JitCodeCreator` which will be registered on the `your_key`.
+Note: Add new `KernelTuples` if necessary，your can refer to `XYZNTuples`.
+Specialie method `JitCodeKey` when add new attribute type。
+2. Add more functions in `more`，you can use any third party you wish, like mkl, mkldnn or intrinsic code to reach the best performance.

+# JIT Kernel
+
+结合函数模板和JIT生成需要的kernel函数。
+这里的kernel是比Operator中kernel更小级别的算子单元，更侧重的是在不同硬件上的性能。可以有多重第三方库的实现，每种实现有自己的`UseMe`函数负责什么条件下可以被调用。
+这里实现的函数可以非常细粒度的函数方法，比如Vector MUL， 也可以是一个复杂的逻辑比如LSTM等。复杂的逻辑也可以由自己的底层函数拼接而成。
+目前仅支持CPU上的高性能计算。

+
+基本类的定义都放在根目录下，根目录下包括gen,more和refer三个目录。每个目录下都是一种或者多种实现，每种kernel算子都需要有reference的实现，用作单元测试的基准，其他的实现都是可选的。
+- gen: 代表使用jit生成的code，需要依赖xbyak库。该实现最关心的就是性能。
+- refer: 代表reference的实现，每种kernel算子都需要有在CPU上的reference的实现，他主要关心的算法逻辑的正确性。
+- more: 下面可以放入跟多实现，可以包括mkl，mkldnn，intrinsic，openblas等，也可以是自身已有的kernel组合。
+
+## 动态获取
+
+提供一个`jit::Get`方法，根据kernel类别获取，每种实现都有自己的使用范围，根据范围动态和当前条件选择需要的kernel函数。
+
+## 测试
+
+- 逻辑测试
+    所有实现都要与refer的code对比，需要满足精度要求， 包括float和double的数据类型
+- 性能测试
+    所有实现的性能对比，并且与最终的`jit::Get`方法对比，该方法拿到的性能需要在各种条件下都是最好的。
+
+# 如何添加新的算子
+
+- 在`KernelType` 中添加 `your_key` .
+- 实现Reference 的逻辑，这个是必须是在CPU上的实现，并且不能依赖任何第三方库。实现后在`refer/CmakeLists.txt`中添加`USE_JITKERNEL_REFER(your_key)`来使用该kernel.
+- (optional) 实现更多的算法在`more`目录下，可以依赖mkl，intrinsic或者mkldnn等第三方库。
+- (optional) 实现基于Xbyak的生成code，在`gen`目下。 jitcode需要实现自己的`JitCodeCreator`，并注册在与refer相同的`KernelType`上。
+- 必要时可以添加新的`KernelTuples`，可以参考`XYZNTuples`，新加的Attr类型需要特例化`JitCodeKey`方法。
+- 在`test.cc`中添加unit test，至少需要测试`float`和`double`两种数据类型，如有必要需要支持额外的数据类型，比如`int8`的相关函数。
+- 在`benchmark.cc`中添加相应的性能对比，同一种kernel需要对比所有实现，并且确保`jit::Get`得到的实现一直是速度最快的。
+
+# 优点
+- 统一的Get方法，接口简单。
+- 同一套逻辑可以有多套实现，可以依赖多套第三方库，互不影响。
+- 目录结构清晰，不会在某个文件中有多个宏定义，导致的可读性差问题。
+- 优化方便，可以直接针对某种属性针对性优化，并不影响其他属性下的性能。
+- 可以支持多种平台，包括Linux，Mac 和 Windows，至少可以保证每种平台都可以正常work。后期也可以针对不同平台有针对的优化。框架层面可以使用统一接口，不必关心底层实现。
