+The implementation behind it can be divided into two parts, **Backward Operator Creating** and **Backward Operator Building**.
+
+### Backward Operator Registry
+
+A backward network is built up with several backward operators. Backward operators take forward operators' inputs, outputs, and output gradients and then calculate its input gradients.
| | forward operator | backward operator
| ---------------------- | ---------------- |------------------------- |
| **Operator::inputs_** | Inputs | Inputs, Outputs, OutputGradients |
| **Operator::outputs_** | Outputs | InputGradients |
- In most cases, there is a one-to-one correspondence between forward and backward operators. These correspondences are recorded by a global hash map(`OpInfoMap`). To follow the philosophy of minimum core and make operators pluggable, the registry mechanism is introduced.

+### Backward Network Building
-A backward network is a series of backward operators. The main idea of building a backward network is creating backward operators in the inverted sequence and put them together.

+A backward network is a series of backward operators. The main idea of building a backward network is creating backward operators in the inverted sequence and append them together one by one. There is some corner case need to process specially.
1. Op
- when the input forward network is a Op, return its gradient Operator Immediately.
+ When the input forward network is an Op, return its gradient Operator Immediately. If all of its outputs are in no gradient set, then return a special `NOP`.
2. NetOp
- when the input forward network is a NetOp, it need to call the sub NetOp/Operators backward function recursively. During the process, we need to collect the `OutputGradients` name according to forward NetOp.
+ In our design, the network itself is also a kind of operator(**NetOp**). So the operators contained by a big network may be some small network. When the input forward network is a NetOp, it needs to call the sub NetOp/Operators backward function recursively. During the process, we need to collect the `OutputGradients` name according to the forward NetOp.
+
+3. RnnOp
+
+ RnnOp is a nested stepnet operator. Backward module need to recusively call `Backward` for every stepnet.
+
+4. Sharing Variables
+
+ **sharing variables**. As illustrated in the pictures, two operator's share the same variable name of W@GRAD, which will overwrite their sharing input variable.

+5. Part of Gradient is Zero.
+ In the whole graph, there is some case of that one operator's gradient is not needed, but its input's gradient is a dependency link of other operator, we need to fill a same shape gradient matrix in the position. In our implement, we insert a special `fillZeroLike` operator.
- Then collect the sub graph `OutputGradients`/`InputGradients` as the NetOp's and return it.
+Follow these rules above, then collect the sub graph `OutputGradients`/`InputGradients` as the NetOp's and return it.

+1. The parameter variable W and it's optimizer subgraph are placed on the parameter server.
+1. Operators are added to the subgraphs.
+ - *Send* sends data to the connected *Recv* operator. The
+ scheduler on the receive node will only schedule *Recv* operator
+ to run when the *Send* operator has ran (the *Send* OP will mark
+ the *Recv* OP runnable automatically).
+ - *Enueue* enqueues the input variable, it can block until space
+ become available in the queue.
+ - *Dequeue* outputs configurable numbers of tensors from the
+ queue. It will block until the queue have the required number of
+ tensors.
+
+
+### Benefits
+
+- Model parallelism become easier to implement: it's an extension to
+ the trainer - parameter server approach. we already have the
+ communication OPs, but need to extend the graph converter's
+ placement functionality.
+
+- User-defined optimizer is easier to add - user can now express it as
+ a subgraph.
+
+- No more duplication logic inside the trainer and the parameter
+ server mentioned in the background section.
+
+### Challenges
+
+- It might be hard for the graph converter to cut a general graph
+ (without any hint for which subgraph is the optimizer). We may need
+ to label which subgraph inside the OP graph is the optimizer.
+
+- It's important to balance the parameter shards of on multiple
+ parameter server. If a single parameter is very big (some
+ word-embedding, fully connected, softmax layer), we need to
+ automatically partition the single parameter onto different
+ parameter servers when possible (only element-wise optimizer depends
+ on the parameter variable).
+
+### Discussion
+
+- In the "Aync SGD" figure, the "W" variable on the parameter server
+ could be read and wrote concurrently, what is our locking strategy?
+ E.g., each variable have a lock cpp method to be invoked by every
+ OP, or, have a lock OP.
+
+- Can the Enqueue OP be implemented under our current tensor design
+ (puts the input tensor into the queue tensor)?
+
+- *Dequeue* OP will have variable numbers of output (depends on the
+ `min_count` attribute), does our current design support it? (similar
+ question for the *Add* OP)
