+# 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。

+    User can use :code:`py_func` to register operators in Python side.

+    :code:`func` in forward part, and call :code:`backward_func` in
+    backward part (if :code:`backward_func` is not None).
+
+    User should set the right data type and shape of :code:`out` before
+    calling this function. However, data types and shapes of gradients of
+    :code:`out` and :code:`x` would be inferred automatically.
+
+    Input orders of :code:`backward_func` would be: forward inputs
+    :code:`x`, forward outputs :code:`out` and backward input gradients of
+    :code:`out`. If some variables of :code:`out` have no gradient, the input
+    tensor would be None in Python side. If some variables of :code:`in` have
+    no gradient, users should return None.
+
+    This function can also be used to debug the running network. User can
+    add a :code:`py_func` operator without output, and print input 
+    :code:`x` inside :code:`func`.
+
+    Args:
+        func (callable): forward Python function.
+        x (Variable|list(Variable)|tuple(Variable)): inputs of :code:`func`.

+            should create :code:`out` beforehand. 
+        backward_func (callable|None): backward Python function.
+                                       None means no backward. Default None.
