+    def create_forward_op(self):
+        # create RNNOp
+        self.forward_op = DynamicRecurrentOp(
+            # inputs


inlinks => inputs
boot_memories => initial_memory_value
step_net => step
outlinks => outputs
pre_memories => ex_memory

As you are making something innovative, I guess you don't want to copy †he terminology simply from Caffe2.

python/paddle/v2/framework/tests/test_dynamic_recurrent_op.py

+            boot_memories=["h_boot"],
+            step_net="stepnet",
+            # outputs
+            outlinks=["h@mem"],


What is the convention to of the name h@mem and h@pre? What does the @ here mean?

Currently, the python API is not completed yet, so the high-level syntax as we described before cannot be used in this unit test.
Both h@mem and h@pre are some underlying names of memory and ex-memory, the work to define these two names should be done by the python API in the future.

+        a = set()
+        backward_op = core.DynamicRecurrentOp.backward(self.forward_op, a)
+
+    def create_step_net(self):


In the design, we use Python's with to construct the step block. It seems that this Python test should also do that.

This is an underlying API, the with-statement syntax is not supported yet because the python API is still under developing.

python/paddle/v2/framework/tests/test_dynamic_recurrent_op.py

+        a = set()
+        backward_op = core.DynamicRecurrentOp.backward(self.forward_op, a)
+
+    def create_step_net(self):


We are not going to do NetOp, but block, here the step is not represented by a NetOp instance, but a block. We mustn't go on using the name "step_net".

Currently, these codes still focus on the primary logic of RNN its own. This implementation is based on NetOp because that is stable and simpler.

I will start the migration to block and executor on next Monday.

+   * Link the pre-state of the first time step to the `boot-state` in parent's
+   * scope.
+   */
+  void LinkBootState(const rnn::MemoryAttr& memory);


As we talked before, it is not boot, but bootstrap. A more plain name is initial.

paddle/operators/dynamic_recurrent_op.h

+  /*
+   * different `Run` method for forward and backward.
+   */
+  template <ComputeMode _>


What are the possible values of ComputeMode? Why do we need the _ here? We need at least a class comment here to explain such stuff.

+
+    // Attributes stored in AttributeMap
+    AddAttr<std::vector<std::string>>(name.pre_memories,
+                                      "names of pre-memories");


pre-memory => ex-memory

wangkuiyi · 2017-10-15T14:37:33Z

+  std::map<std::string, framework::TensorArray> step_outputs_;
+  std::map<std::string, std::vector<framework::DySeqMeta>> dy_seq_metas_;
+  rnn::Argument arg_;
+  ArgCache cache_;


What is the purpose of ArgCache? I saw that the terminology in your code includes "inlinks", "outlink", and "memory". Are they in "ArgCache", or what is the relationship between them and "argument"?

This is a cache of all the arguments that located in the parent scope. RNN's computation is split into a bunch of protected methods, it is painful and ugly to pass in the arguments throughout all the member functions, so a cache called ArgCache is added as a member.

There is only one public member function of RNNAlgorthm, which is Run, refresh the ArgCache when Run is invoked.

including inlinks, outlinks, memories and so on.
