The `ProgramDesc` can be executed by an interpreter(i.e. the `executor` concept in Fluid).

The parameters will be initialised on `GPU0` by startup program and will broadcast to multi-GPUs. The main program will be duplicated into multi-GPUs. The gradient will be merged during each iteration, and each device will optimize parameters independently. Since the gradients on each device will be merged before parameter optimization, the parameters will be the same on each device and it does not need to be broadcast the parameters. + +![alt](images/parallel_executor_overview.png) + +There are several optimizations for this logic. + +1. We use an alternate representation in ParallelExecutor. It because the device information is critical for performance optimization. +2. The execution is out-of-order, i.e., an operator will be executed whenever the inputs of the operator are ready. + * GPU is a high-performance device; only one CPU thread cannot fulfil one GPU. So there is a thread pool to execute operators. + * Out-of-order also helps transpilers to generate `ProgramDesc`. It is no need to concern about the best order of performance when implementing a transpiler. +3.

To implement concurrent execution, we uses an `SSA` graph as an intermedia representation of `ProgramDesc`. + +The `Program` is a directed acyclic graph, since a variable can be assigned multiple times. We enforce a variable will be assigned once, by adding version number to varaibles. We parsing the `Program` into a `SSA` graph. Also, ProgramExecutor duplicate `Program` into multi-devices. We also add a device number to varaibles and insert `NCCLAllReduce` into Graph. + +The data structure of `SSA` graph is: + +```c++ +struct VarHandleBase { + OpHandleBase* generated_op_; + vector pending_ops_; + + string name; + Place place; + size_t version; +}; + +struct OpHandleBase { + vector inputs_; + vector outputs_; +}; + +struct SSAGraph { + // vars on each devices. + // * the vars in each map in vector is on different device. + // * the map is mapping a variable name to variable handles + // with different versions + vector>> vars_; + + // All ops + vector ops_; +}; +``` +The variable handles are the wrapper of `Variables`. The operator handles are the wrapper of `OperatorBase`. Some `OpHandle` is not an `OperatorBase`, such as `NCCLAllReduceOpHandle`, because `AllReduceOpHandle` will use new device contexts. + +When the `ProgramDesc` converted into an `SSA` Graph, the [data hazard](https://en.wikipedia.org/wiki/Hazard_(computer_architecture)) problem is also need to be taken care. The dummy variables, which represent the dependency between operators, will be manually inserted into SSA graph to resolve the [data hazard](https://en.wikipedia.org/wiki/Hazard_(computer_architecture)) problem. + +## Execute SSA Graph + +The SSA graph can be out-of-order executed by an approximate [topological sorting](https://en.wikipedia.org/wiki/Topological_sorting) algorithm. The algorithm is + +1. Maintaining a map of an operator and its needed input number. +2. If a variable is not generated by an operator, i.e., `var.generated_op == nullptr`, decrease the needed input number of its pending operators. +3. If there is an operator which needed input number is decreased to zero, just run this operator. +4. After run this operator, just mark the variables are generated and repeat step 2 until all variables are generated. + +Running an operator can be asynchronized. There is a thread pool to execute an `SSA` graph. + +## Synchronize GPU Kernels + +The GPU is a non-blocking device. The different streams need be synchronized when switing streams. In current implementation, the synchronization based on the following algorithm: + +1. `OpHandle` will record `DeviceContext` that it is used. +2. In `OpHandle::Run`, if the `DeviceContext` of current operator is different from `DeviceContext` of any input variable, just wait the generate operator of this input variable. + +The `wait` are implemented by two strategies: + +1. Invoke `DeviceContext->Wait()`, It will wait all operators on this device contexts complete. +2. Uses `cudaStreamWaitEvent` to sending a event to the stream. It is a non-blocking call. The wait operators will be executed in GPU. + +Generally, the `cudaStreamWaitEvent` will have a better perforamnce. However, `DeviceContext->Wait()` strategy is easier to debug. The strategy can be changed in runtime. + +## What's next? + +* Merging gradient of dense parameters has been done. However, the merging of sparse parameters has not been done. +* The CPU version of Parallel Executor has not been implemented. The out-of-order logic will make CPU compuatation faster, too. +* A better strategy to merge gradients can be introduced. We can shrink the gradients from `float32` to `int8` or `int4` while merging. It will significantly speed up multi-GPUs training without much loss of precision. +* Combine multi-Nodes implementation. By the benifit of out-of-order, sending and recving operator can be an blocking operator, and the transpiler does not need to concern about the best position of operator. diff --git

How to use :code:`paddle.layer.memory`'s attribute :code:`name` +---------------------------------------------------------------------- + +* :code:`paddle.layer.memory` is used to get the output of a layer's last timestep and the layer is specified by the attribute :code:`name` . Thus, :code:`paddle.layer.memory` will associate with the layer that has the same value of attribute :code:`name` , and uses the output of the layer's last timestep as the input of its current timestep. + +* All the PaddlePaddle's layers have a unique name, which is set by the attribute :code:`name` . PaddlePaddle will automatically set it for the user when it is not explicitly set. :code:`paddle.layer.memory` is not a real layer, its name is set by the attribute :code:`memory_name` and PaddlePaddle will also automatically set it when the user does not explicitly set.

Recurrent layer implemented by recurrent_group: + + * Using this type of recurrent layers, users can access the intermediate value calculated by the recurrent unit within a timestep (eg: hidden states, memory cells, etc.) + * :code:`paddle.networks.lstmemory_group` belongs to this type of recurrent layers. + +2. Recurrent layer implemented as a complete operation： + + * Users can only access output values when using this type of recurrent layers. + * :code:`paddle.networks.lstmemory_group` , :code:`paddle.networks.simple_lstm` and :code:`paddle.networks.bidirectional_lstm` belong to this type of recurrent layer； + +By implementing recurrent layer as a complete operation, CPU and GPU calculations can be optimized. Therefore, the second type of recurrent layer is more efficient than the first one. In practical applications, we propose to use the second type of recurrent layers if there is no need to access the intermediate variable of LSTM. + +In addition, PaddlePaddle also contains a kind of LSTM calculation unit: :code:`paddle.networks.lstmemory_unit`: + + * Unlike the recurrent layer described above, :code:`paddle.networks.lstmemory_unit` defines the computational process of an LSTM unit in a timestep. It is not a complete recurrent layer, nor can it receive sequence data as input. + * :code:`paddle.networks.lstmemory_unit` can only be used as a step function in recurrent_group. + +5. Can Softmax's calculation dimension be specified？ +-------------------------------------------------------------------- + +We can't specify calculation dimension for PaddlePaddle's softmax. It can only be calculated by rows. +In image tasks, for NCHW, if you need to calculate softmax in C dimension, you could use :code:`paddle.layer.switch_order` to change the dimension order, that is, convert NCHW to NHWC, then do the reshape operation and calculate softmax. + +6. Does PaddlePaddle support variable-dimensional data inputs +---------------------------------------------------------------- + +PaddlePaddle provides :code:`paddle.data_type.dense_array` to support variable-dimensional data input. Simply set the dimension of the data layer to a value larger than the dimension of the input data for occupancy. diff --git a/doc/v2/howto/cmd_parameter/index_en.rst b/doc/v2/howto/cmd_parameter/index_en.rst index 0e3c72d27aca063f1b6f1c23e55718dba373c40a..f49683948ef78f363e2439cc25332431830eeb24 100644 --- a/doc/v2/howto/cmd_parameter/index_en.rst +++ b/doc/v2/howto/cmd_parameter/index_en.rst @@ -2,10 +2,25 @@ Set Command-line Parameters =========================== +The implementation of deep learning algorithms has a variety of characteristics, such as running environment, running stage, structure of the model and the traning strategy.
