## Evaluator Design
### The Problem
### Problem Statement
During training or serving, we provide the evaluation function to measure the model performance, e.g., accuracy, precision. In the operator based framework design, the data go through the network pipeline batch by batch. As a result, inside the operator, we only can calculate one minibatch metrics. We need to provide a mechanism to calculate the metrics for each N pass/batch the user wanted.
During training or inference, we provide an evaluation function to measure the model performance, for example, accuracy, precision, etc. In the operator based framework design, the data passes through the network pipeline batch by batch. As a result, inside the operator, we only calculate the metrics for one minibatch. Thus, we need to provide a mechanism to calculate the metrics for each N pass/batch the user wants.
### Evaluator Design
Currently, every operation is expressed in the graph. we divide the evaluator process into three steps.
Currently, every operation is expressed in the graph. We divide the evaluator process into three steps.
1. Initialize the metric state and add it into the block.
2. Calculate the statistic of the metric state in every mini-batch. The single operator is only responsible for calculating necessary statistics for one mini-batch. For example, accuracy operator only calculate a minibatch data if run once.
2. Calculate the concerned metrics for every mini-batch. The single evaluator operator is only responsible for calculating the necessary statistics for one mini-batch. For example, the accuracy operator only calculates the accuracy for a minibatch data if run once.
3. Merge the mini-batch statistics to form the evaluation result for multiple mini-batches. When it comes to distributed training/Multi-GPU training, aggregate the value from different devices.
### Implementation
This design is shown in python API.
Each metric operator need to caculate the metric statistic and return the batch aware states, Python side responsible for accumulate the states for each pass.

- [Eigen](https://github.com/RLovelett/eigen) >= 3.3 supports float16 calculation on both GPU and CPU using the `Eigen::half` class. It is mostly useful for Nvidia GPUs because of the overloaded arithmetic operators using cuda intrinsics. It falls back to using software emulation on CPU for calculation and there is no special treatment to ARM processors.
- [ARM compute library](https://github.com/ARM-software/ComputeLibrary) >= 17.02.01 supports NEON FP16 kernels (requires ARMv8.2-A CPU).
### CUDA version issue
There are currently three versions of CUDA that supports `__half` data type, namely, CUDA 7.5, 8.0, and 9.0.
CUDA 7.5 and 8.0 define `__half` as a simple struct that has a `uint16_t` data (see [`cuda_fp16.h`](https://github.com/ptillet/isaac/blob/9212ab5a3ddbe48f30ef373f9c1fb546804c7a8c/include/isaac/external/CUDA/cuda_fp16.h)) as follows:
```
typedef struct __align__(2) {
unsigned short x;
} __half;
typedef __half half;
```
This struct does not define any overloaded arithmetic operators. So you have to directly use `__hadd` instead of `+` to correctly add two half types:
```
__global__ void Add() {
half a, b, c;
c = __hadd(a, b); // correct
c = a + b; // compiler error: no operator "+" matches these operands
}
```
CUDA 9.0 provides a major update to the half data type. The related code can be found in the updated [`cuda_fp16.h`](https://github.com/ptillet/isaac/blob/master/include/isaac/external/CUDA/cuda_fp16.h) and the newly added [`cuda_fp16.hpp`](https://github.com/ptillet/isaac/blob/master/include/isaac/external/CUDA/cuda_fp16.hpp).
Essentially, CUDA 9.0 renames the original `__half` type in 7.5 and 8.0 as `__half_raw`, and defines a new `__half` class type that has constructors, conversion operators, and also provides overloaded arithmetic operators such as follows:
```
typedef struct __CUDA_ALIGN__(2) {
unsigned short x;
} __half_raw;
struct __CUDA_ALIGN__(2) __half {
protected:
unsigned short __x;
public:
// constructors and conversion operators from/to
// __half_raw and other built-in data types
}
typedef __half half;
__device__ __forceinline__
__half operator+(const __half &lh, const __half &rh) {
return __hadd(lh, rh);
}
// Other overloaded operators
```
This new design makes `c = a + b` work correctly for CUDA half data type.
## Implementation
The float16 class holds a 16-bit `uint16_t` data internally.

我们会把MKL-DNN作为第三方库集成进PaddlePaddle,整体框架图
我们会把MKL-DNN会作为第三方库集成进PaddlePaddle,与其他第三方库一样,会在编译PaddlePaddle的时候下载并编译MKL-DNN。
同时,为了进一步提升PaddlePaddle在基本数学运算的计算速度,我们也将MKLML即(MKL small library\[[1](#references)\])
作为另一个第三方库集成进PaddlePaddle,它只会包括生成好的动态库和头文件。
MKL,MKLML以及MKL-DNN三者关系如下表:

```
### CMake
我们会在`CMakeLists.txt`中会给用户添加一个`WITH_MKL`的开关,他是负责`WITH_MKLML``WITH_MKLDNN`的总开关。
`CMakeLists.txt`中提供一个与MKL有关的总开关:`WITH_MKL`,它负责决定编译时是否使用MKLML和MKL-DNN
当打开`WITH_MKL`时,会开启MKLML的功能,作为PaddlePaddle的CBLAS和LAPACK库,同时会开启Intel OpenMP用于提高MKLML的性能。 如果系统支持AVX2指令集及以上,同时会开启MKL-DNN功能。
- `WITH_MKLML` 控制是否使用MKLML库。
当打开`WITH_MKL`时,会自动使用MKLML库作为PaddlePaddle的CBLAS和LAPACK库,同时会开启Intel OpenMP用于提高MKLML的性能。
编译时会把对应的头文件和库放在`build/third_party/install/mklml/*`目录下对应的地方。
MKLML的库目前都是动态库,主要包括`libiomp5.so``libmklml_intel.so`
- `WITH_MKLDNN` 控制是否使用MKL-DNN。
当开启`WITH_MKL`时,会自动根据硬件配置[[2](#references)]选择是否编译MKL-DNN。
编译时会把对应的头文件和库放在`build/third_party/install/mkldnn/*`目录下对应的地方。
MKL-DNN的库目前只有动态库`libmkldnn.so`
当关闭`WITH_MKL`时,MKLML和MKL-DNN功能会同时关闭。
### Matrix
目前在PaddlePaddle中数据都是以`NCHW`的格式存储,但是在MKL-DNN中的排列方式不止这一种。
所以我们定义了一个`MKLDNNMatrix`用于管理MKL-DNN数据的不同格式以及相互之间的转换。
所以,我们会在`cmake/external`目录新建`mkldnn.cmake``mklml.cmake`文件,它们会在编译PaddlePaddle的时候下载对应的软件包,并放到PaddlePaddle的third party目录中。
<div align="center">
<img src="image/matrix.png"><br/>
Figure 3. MKLDNNMatrix
</div>
### Layers
所有MKL-DNN相关的C++ layers,都会按照PaddlePaddle的目录结构存放在
`paddle/gserver/layers`中,并且文件名都会一以*MKLDNN*开头。
所有MKL-DNN的Layers都会继承于`MKLDNNLayer`,该类继承于PaddlePaddle的基类`Layer`
`MKLDNNLayer`中会提供一些必要的接口和函数,并且会写好`forward``backward`的基本逻辑,
子类只需要使用定义好的接口,实现具体的函数功能即可。
<div align="center">
<img src="image/layers.png"><br/>
Figure 4. MKLDNNLayer
</div>
每个MKLDNNLayer都包含用于内部存储和外部存储的一系列MKLDNNMatrix:
所有MKL-DNN的layers都会继承于一个叫做`MKLDNNLayer`的父类,该父类继承于PaddlePaddle的基类`Layer`
- 内部存储(internel memory):`inVal_`,`inGrad_`,`outVal_``outGrad_`,分别代表输入数据,输入梯度,输出数据和输出梯度。
- 外部存储(external memory):都是以ext开头,比如`extInVal_``extInGrad_`,它们主要是用于,
当数据格式与PaddlePaddle默认的`NCHW`格式不匹配时,转换内存的工作。
需要注意的是,PaddlePaddle的activation会直接使用`output_.value``output_.grad`
所以`extOutVal_``extOutGrad_`必须分别与`output_.value``output_.grad`共享内存,
如果不需要外部存储用于转换,那么对应的内部存储也会与它们共享内存。
- 转换函数(resetXXX): 包括`resetInValue``resetInGrad``resetOutValue``resetOutGrad`
表示对输入数据,输入梯度,输出数据和输出梯度的转换。
这些函数会根据输入参数重新设置内部和外部存储,当然这两者也可以相等,即表示不需要转换。
`MKLDNNLayer`中会提供一些必要的接口和函数,并且会写好`forward``backward`的基本逻辑。部分函数定义为纯虚函数,子类只需要实现这些函数即可
注意:每个`MKLDNNlayer`的子类只需要使用内部存储就可以了,所有外部的转换工作都会在reset系列函数中都准备好
### Activations
由于在PaddlePaddle中,激活函数是独立于layer概念的,所以会在`paddle/gserver/activations`目录下添加`MKLDNNActivation.h``MKLDNNActivation.cpp`文件用于定义和使用MKL-DNN的接口。
在重构前的PaddlePaddle中,激活函数是独立于`Layer`的概念,并且输入输出都是共用一块内存,
所以添加了对应的`MKLDNNActivation`来实现,方式类似于`MKLDNNLayer`
### Parameters
对于有参数的层,我们会保证`MKLDNNLayer`使用的参数与PaddlePaddle申请的buffer共用一块内存。
如果存在数据排列格式不一样的情况时,我们会在网络训练之前把格式转换为MKL-DNN希望的格式,
在训练结束的时候再保存为PaddlePaddle的格式,但是整个训练过程中不需要任何转换。
这样既使得最终保存的参数格式与PaddlePaddle一致,又可以避免不必要的转换。
### Gradients
由于MKL-DNN的操作都是直接覆盖的形式,也就是说输出的结果不会在原来的数据上累加,
这样带来的好处就是不需要一直清空memory,节省了不必要的操作。
但是注意的是,当网络出现分支且在`backward`的时候,需要累加不同Layer传过来的梯度。
所以在`MKLDNNlayer`中实现了一个merge的方法,此时每个小分支的`Input Gradient`
会先临时保存在`MKLDNNMatrix`中,由分支处的Layer负责求和,并把结果放到当前层的`output_.grad`中。
所以整体上,在实现每个子类的时候就不需要关心分支的事情了。
### Weights
由于有些layer是含有参数的,我们会尽量让MKL-DNN的参数与PaddlePaddle中`parameter`共享一块内存。
同时,由于MKL-DNN在训练时使用的参数layout可能与PaddlePaddle默认的`nchw`不一致,我们会在网络训练的开始和结束时分别转换这个layout,使得最终保存的参数格式与PaddlePaddle一致。
<div align="center">
<img src="image/gradients.png"><br/>
Figure 5. Merge Gradients
</div>
### Unit Tests
会在`paddle/gserver/test`目录下添加`test_MKLDNN.cpp``MKLDNNTester.*`用于MKL-DNN的测试。
测试分为每个layer(或activation)的单元测试和简单网络的整体测试。
我们会添加`test_MKLDNN.cpp``MKLDNNTester.*`用于MKL-DNN的测试。
测试分为每个Layer(或Activation)的单元测试和简单网络的整体测试。
每个测试会对比PaddlePaddle中CPU算出的结果与MKL-DNN的结果,小于某个比较小的阈值认为通过。
### Protobuf Messages
根据具体layer的需求可能会在`proto/ModelConfig.proto`里面添加必要的选项。

我们总结出一些特别需要注意的点:
1. 使用**deviceId_**。为了尽可能少的在父类Layer中添加变量或者函数,我们决定使用已有的`deviceId_`变量来区分layer的属性,定义`-2``MKLDNNLayer`特有的设备ID。

2. 重写父类Layer的**init**函数,修改`deviceId_``-2`,代表这个layer是用于跑在MKL-DNN的环境下。
3. 创建`MKLDNNMatrix`,同时继承`CpuMatrix``mkldnn::memory`。用于管理MKL-DNN会用到的相关memory函数、接口以及会用的到格式信息。
4. 创建`MKLDNNBase`,定义一些除了layer和memory相关的类和函数。包括MKL-DNN会用到`MKLDNNStream``CPUEngine`,和未来可能还会用到`FPGAEngine`等。
5. 每个`MKLDNNlayer`都会有`inVal_`,`inGrad_`,`outVal_``outGrad_`,分别代表input value, input gradient,output value和output gradient。他们会存放MKL-DNN用到的internal memory。同时还会定义以*ext*开头的`MKLDNNMatrix`(表示external的memory),主要是在格式与PaddlePaddle默认的`nchw`格式不匹配时,用于转换内存的工作。必要的转换函数也会在`MKLDNNLayer`中提前定义好,每个子类只需要调用定义好的reset buffer函数即可。
6. 每个`MKLDNNlayer`的resetbuffer相关的函数(包括reset input、output的Value和grad),他们会根据输入参数reset internal和external的memory,当然这两者也可以相等,即表示不需要转换。只需要把握一个原则,每个`MKLDNNlayer`的子类,只需要使用internal的memory就可以了,所有external的转换工作在父类的reset函数中都提前准备好了。
7. 一般来说,external的memory会尽量与PaddlePaddle中的`value``grad`共享内存。同时每个`MKLDNNLayer`中的external output value和gradient(也就是`extOutVal_``extOutGrad_`)必须分别与`output_.value``output_.grad`共享内存,因为PaddlePaddle的activation会直接使用`output_.value``output_.grad`。如果不需要external的buffer用于转换,那么internal的buffer也会与他们共享内存。
8. 如果MKL-DNN layer的后面接有cpu device,那么就会使`output_.value``extOutVal_`共享内存,同时数据格式就是`nchw`,这样下一个cpu device就能拿到正确的数据。在有cpu device的时候,external的memory的格式始终是`nchw`或者`nc`
9. 由于MKL-DNN的输出操作都是覆盖data的,不是在原来的数据上累加,所以当网络出现分支时,在`backward`时会需要merge不同layer的梯度。`MKLDNNlayer`中会实现merge的方法,此时每个小分支的input gradient会先临时保存在一个`MKLDNNMatrix`中,由分支处的layer负责求和,并把结果放到这个layer的`output_.grad`中。所以整体上,每个子类并不会需要关心分支的事情,也是在父类都实现好了。
10. 在原来的`FLAGS`中添加一个`use_mkldnn`的flag,用于选择是否使用MKL-DNN的相关功能。

在有普通的CPU layer时, `extOutVal_``extOutGrad_`的格式始终是`NCHW`或者`NC`

PaddlePaddle v0.10.0 uses the "trainer-parameter server"
architecture. We run multiple replicated instances of trainers (runs
the same code written by the user) and parameter servers for
distributed training. This architecture served us well, but has some
limitations:
PaddlePaddle version 0.10.0 uses the "trainer-parameter server" architecture. We run multiple instances of trainers (where each trainer runs the same model) and parameter servers for distributed training. This architecture serves well, but has few limitations:
1. Need to write special code to handle tasks which should only be run
by a single trainer. E.g., initializing model and saving model.
1. There is a need to write special code that handles tasks which should only be run on a single trainer. E.g., initializing the model, saving the model etc.
2. Model parallelism is hard: need to write if-else branches conditioned
on the trainer ID to partition model onto each trainer, and manually
write the inter-model-shard communication code.
2. Model parallelism is hard: It would need all the if-else branches conditioned on the trainer ID to partition the model onto the trainers, and eventually manually writing out the inter-model-shard communication code to communicate between different trainers.
3. The user can not directly specify the parameter update rule: need
to modify the parameter server C++ code and compile a new
binary. This adds complication for researchers: A lot of extra
effort is required. Besides, the training job submission program
may not allow running arbitrary binaries.

## Analysis
We will assume the user writes the trainer program by Python, the same
analysis holds if the trainer program is written in C++.
The assumption is that the user writes the trainer program in either Python or C++.
### Limitation 1
If we look at the Python code that the user writes, there are two
kinds of functionalities:
There are two basic functionalities in the trainer program:
- The training logic such as load / save model and print log.
- The neural network definition such as the definition of the data
layer, the fully connected layer, the cost function and the
1. The training logic such as loading / saving the model and printing out the logs.
2. The neural network definition such as the definition of the data layer, the fully connected layer, the cost function and the
optimizer.
When we training with PaddlePaddle v0.10.0 distributedly, multiple
replicated Python instances are running on different nodes: both the
training logic and the neural network computation is replicated.
When we train using PaddlePaddle v0.10.0 in a distributed fashion, multiple instances of the same Python code are run on different nodes, hence both: the
training logic as well as the neural network computation logic, is replicated.
The tasks that should only run once all belong to the training logic,
if we only replicate the neural network computation, but do **not**
replicate the training logic, the limitation could be solved.
The tasks that only need to be run once belong to the training logic. Hence if we only replicate the neural network computation part, and do **not**
replicate the training logic, the limitation mentioned above can be avoided.
### Limitation 2
Model parallelism means running a single model on multiple nodes by
partitioning the model onto different nodes and managing the
inter-model-shard communications.
Model parallelism means that a single model is partitioned into different components and each node runs one of the component separately. This comes at the extra cost of managing the
inter-model-shard communication between nodes.
PaddlePaddle should be able to modify the nerual network computation
definition to support model parallelism automatically. However, the
computation is only specified in Python code, and PaddlePaddle can not
modify Python code.
PaddlePaddle should ideally be able to modify the neural network computation and figure out the support for model parallelism automatically. However, the
computation is only specified in Python code which sits outside of PaddlePaddle, hence PaddlePaddle can not support the feature in this setup.
Just like compiler uses a intermediate representation (IR) so that
programmer does not need to manually optimize their code in most of
the cases - the compiler will optimize the IR:
Similar to how a compiler uses an intermediate representation (IR) so that the programmer does not need to manually optimize their code for most of the cases, we can have an intermediate representation in PaddlePaddle as well. The compiler optimizes the IR as follows:

We can have our own IR too: PaddlePaddle can support model parallel by
converting the IR so the user no longer need to manually do it in
Python:

The IR for PaddlePaddle after refactor is called `Block`, it specifies
the computation dependency graph and the variables used in the
computation.

### Limitation 3
The user can not directly specify the parameter update rule for the
parameter server because the parameter server does not use the same
computation definition as the trainer. Instead, the update rule is
baked in the parameter server. The user can not specify the update
rule in the same way of specifying the trainer computation.
The user can not directly specify the parameter update rule for the parameter server in the Python module, since the parameter server does not use the same computation definition as the trainer. Instead, the update rule is baked inside the parameter server. The user can not specify the update rule explicitly.
This could be fixed by making the parameter server run the same
computation definition as the trainer. For a detailed explanation,
please

The above code is what a typical Python trainer code is, the neural network topology is built using the helper functions such as `paddle.layer.fc`. Training is done by calling `session.eval` iteratively.
#### session.eval
As shown in the graph, `session.eval` sends the IR and the evaluation
inputs/targets to the PaddlePaddle cluster for evaluation. The
targets can be any variable in the computation graph. When the target
is the `optimizer` variable, the neural network will be optimized
once. When the target is the `cost` variable, `session.eval` returns
the cost value.

information about `Session`, please

### PaddlePaddle Converter
PaddlePaddle converter automatically converts the IR in the request
(IR and evaluation inputs/targets) from PaddlePaddle Python to new
partitioned IRs and dispatch the new IRs and evaluation inputs/targets
to different PaddlePaddle runtimes. Below are the steps:
The PaddlePaddle converter automatically converts the IR in the request (IR and evaluation inputs/targets) from PaddlePaddle Python to partitioned IRs and dispatches the new IRs and evaluation inputs/targets to different PaddlePaddle runtimes. Below are the steps that are followed :
1. Add `feed` OP that feeds the eval inputs, and `fetch` OP that
fetches the eval targets to the IR.
1. Add a `feed` OP that feeds the eval inputs, and a `fetch` OP that fetches the eval targets to the IR.
1. Extract a new computation (sub)graph with `feed` and `fetch` OP as
the boundary. The runtime does not need to run the OP that is not
dependent by the `fetch` OP.
2. Extract a new computation (sub)graph with the `feed` and `fetch` OPs as the boundary. The runtime does not need to run the OP that is not dependent on the `fetch` OP.
1. Optimizes the computation graph.
3. Optimize the computation graph.
1. Place the OPs in the graph onto different devices on different
PaddlePaddle runtime according to a placement algorithm and device
constraint specified by the user.
4. Place the OPs in the graph onto different devices on different PaddlePaddle runtime according to a placement algorithm and the device constraints specified by the user.
1. Partition the graph according to runtime boundaries and add `send` /
`recv` OP pair on the runtime boundaries.
5. Partition the graph according to runtime boundaries and add `send` / `recv` OP pair on the runtime boundaries.
1. Dispatch the partitioned graph to different PaddlePaddle runtimes.
6. Dispatch the partitioned graph to different PaddlePaddle runtimes.
1. PaddlePaddle runtimes with the `fetch` OP reports evaluation
results back to the converter, the convert reports the evaluation
results back to the PaddlePaddle Python.
7. PaddlePaddle runtimes with the `fetch` OP reports evaluation results back to the converter, the converter reports the evaluation results back to the PaddlePaddle Python.
The output IRs will be cached to optimize the conversion latency.
#### Placement Algorithm
Our first implementation will only support "trainer-parameter server"
placement: the parameters, initializers, and optimizers are placed on
the PaddlePaddle runtimes with the parameter server role. And
everything else will be placed on the PaddlePaddle runtimes with the
trainer role. This has the same functionality of our
"trainer-parameter server" architecture of PaddlePaddle v0.10.0, but
is more general and flexible.

### PaddlePaddle Runtime
The PaddlePaddle runtime owns multiple devices (e.g., CPUs, GPUs) and
runs the IR. The runtime does not need to do OP placement since it's
already done by the converter.

### Training Data
In PaddlePaddle v0.10.0, training data is typically read
with [data reader](../reader/README.md) from Python. This approach is
no longer efficient when training distributedly since the Python
process no longer runs on the same node with the trainer processes,
the Python reader will need to read from the distributed filesystem
(assuming it has the access) and send to the trainers, doubling the
network traffic.
When doing distributed training, the user can still use Python data
reader: the training data are sent with `session.eval`. However should
be used for debugging purpose only. The users are encouraged to use
the read data OPs.

此教程会介绍如何使用Python的cProfile包,与Python库yep,google perftools来运行性能分析(Profiling)与调优。
This tutorial introduces techniques we use to profile and tune the
CPU performance of PaddlePaddle. We will use Python packages
`cProfile` and `yep`, and Google's `perftools`.
运行性能分析可以让开发人员科学的,有条不紊的对程序进行性能优化。性能分析是性能调优的基础。因为在程序实际运行中,真正的瓶颈可能和程序员开发过程中想象的瓶颈相去甚远。
Profiling is the process that reveals performance bottlenecks,
which could be very different from what's in the developers' mind.
Performance tuning is done to fix these bottlenecks. Performance optimization
repeats the steps of profiling and tuning alternatively.
性能优化的步骤,通常是循环重复若干次『性能分析 --> 寻找瓶颈 ---> 调优瓶颈 --> 性能分析确认调优效果』。其中性能分析是性能调优的至关重要的量化指标。
PaddlePaddle users program AI applications by calling the Python API, which calls
into `libpaddle.so.` written in C++. In this tutorial, we focus on
the profiling and tuning of
Paddle提供了Python语言绑定。用户使用Python进行神经网络编程,训练,测试。Python解释器通过`pybind``swig`调用Paddle的动态链接库,进而调用Paddle C++部分的代码。所以Paddle的性能分析与调优分为两个部分:
1. the Python code and
1. the mixture of Python and C++ code.
* Python代码的性能分析
* Python与C++混合代码的性能分析
## Profiling the Python Code
### Generate the Performance Profiling File
## Python代码的性能分析
### 生成性能分析文件
Python标准库中提供了性能分析的工具包,[cProfile](https://docs.python.org/2/library/profile.html)。生成Python性能分析的命令如下:
We can use Python standard
package, [`cProfile`](https://docs.python.org/2/library/profile.html),
to generate Python profiling file. For example:
```bash
python -m cProfile -o profile.out main.py
```
其中`-o`标识了一个输出的文件名,用来存储本次性能分析的结果。如果不指定这个文件,`cProfile`会打印一些统计信息到`stdout`。这不方便我们进行后期处理(进行`sort`, `split`, `cut`等等)。
### 查看性能分析文件
where `main.py` is the program we are going to profile, `-o` specifies
the output file. Without `-o`, `cProfile` would outputs to standard
output.
当main.py运行完毕后,性能分析结果文件`profile.out`就生成出来了。我们可以使用[cprofilev](https://github.com/ymichael/cprofilev)来查看性能分析结果。`cprofilev`是一个Python的第三方库。使用它会开启一个HTTP服务,将性能分析结果以网页的形式展示出来。
### Look into the Profiling File
使用`pip install cprofilev`安装`cprofilev`工具。安装完成后,使用如下命令开启HTTP服务
`cProfile` generates `profile.out` after `main.py` completes. We can
use [`cprofilev`](https://github.com/ymichael/cprofilev) to look into
the details:
```bash
cprofilev -a 0.0.0.0 -p 3214 -f profile.out main.py
```
其中`-a`标识HTTP服务绑定的IP。使用`0.0.0.0`允许外网访问这个HTTP服务。`-p`标识HTTP服务的端口。`-f`标识性能分析的结果文件。`main.py`标识被性能分析的源文件。
where `-a` specifies the HTTP IP, `-p` specifies the port, `-f`
specifies the profiling file, and `main.py` is the source file.
访问对应网址,即可显示性能分析的结果。性能分析结果格式如下:
Open the Web browser and points to the local IP and the specifies
port, we will see the output like the following:

### 寻找性能瓶颈
通常`tottime``cumtime`是寻找瓶颈的关键指标。这两个指标代表了某一个函数真实的运行时间。
将性能分析结果按照tottime排序,效果如下:
Usually, `tottime` and the related `percall` time is what we want to
focus on. We can sort above profiling file by tottime:

We can see that the most time-consuming function is the `built-in
method run`, which is a C++ function in `libpaddle.so`. We will
explain how to profile C++ code in the next section. At this
moment, let's look into the third function `sync_with_cpp`, which is a
Python function. We can click it to understand more about it:

## Profiling Python and C++ Code
### Generate the Profiling File
## Python与C++混合代码的性能分析
To profile a mixture of Python and C++ code, we can use a Python
package, `yep`, that can work with Google's `perftools`, which is a
commonly-used profiler for C/C++ code.
### 生成性能分析文件
C++的性能分析工具非常多。常见的包括`gprof`, `valgrind`, `google-perftools`。但是调试Python中使用的动态链接库与直接调试原始二进制相比增加了很多复杂度。幸而Python的一个第三方库`yep`提供了方便的和`google-perftools`交互的方法。于是这里使用`yep`进行Python与C++混合代码的性能分析
使用`yep`前需要安装`google-perftools``yep`包。ubuntu下安装命令为
In Ubuntu systems, we can install `yep` and `perftools` by running the
following commands:
```bash
apt update
apt install libgoogle-perftools-dev
pip install yep
```
安装完毕后,我们可以通过
Then we can run the following command
```bash
python -m yep -v main.py
```
生成性能分析文件。生成的性能分析文件为`main.py.prof`
to generate the profiling file. The default filename is
`main.py.prof`.
Please be aware of the `-v` command line option, which prints the
analysis results after generating the profiling file. By examining the
the print result, we'd know that if we stripped debug
information from `libpaddle.so` at build time. The following hints
help make sure that the analysis results are readable:
命令行中的`-v`指定在生成性能分析文件之后,在命令行显示分析结果。我们可以在命令行中简单的看一下生成效果。因为C++与Python不同,编译时可能会去掉调试信息,运行时也可能因为多线程产生混乱不可读的性能分析结果。为了生成更可读的性能分析结果,可以采取下面几点措施:
1. Use GCC command line option `-g` when building `libpaddle.so` so to
include the debug information. The standard building system of
PaddlePaddle is CMake, so you might want to set
`CMAKE_BUILD_TYPE=RelWithDebInfo`.
1. 编译时指定`-g`生成调试信息。使用cmake的话,可以将CMAKE_BUILD_TYPE指定为`RelWithDebInfo`
2. 编译时一定要开启优化。单纯的`Debug`编译性能会和`-O2`或者`-O3`有非常大的差别。`Debug`模式下的性能测试是没有意义的。
3. 运行性能分析的时候,先从单线程开始,再开启多线程,进而多机。毕竟如果单线程调试更容易。可以设置`OMP_NUM_THREADS=1`这个环境变量关闭openmp优化。
1. Use GCC command line option `-O2` or `-O3` to generate optimized
binary code. It doesn't make sense to profile `libpaddle.so`
without optimization, because it would anyway run slowly.
### 查看性能分析文件
1. Profiling the single-threaded binary file before the
multi-threading version, because the latter often generates tangled
profiling analysis result. You might want to set environment
variable `OMP_NUM_THREADS=1` to prevents OpenMP from automatically
starting multiple threads.
在运行完性能分析后,会生成性能分析结果文件。我们可以使用[pprof](https://github.com/google/pprof)来显示性能分析结果。注意,这里使用了用`Go`语言重构后的`pprof`,因为这个工具具有web服务界面,且展示效果更好。
### Examining the Profiling File
安装`pprof`的命令和一般的`Go`程序是一样的,其命令如下:
The tool we used to examine the profiling file generated by
`perftools` is [`pprof`](https://github.com/google/pprof), which
provides a Web-based GUI like `cprofilev`.
We can rely on the standard Go toolchain to retrieve the source code
of `pprof` and build it:
```bash
go get github.com/google/pprof
```
进而我们可以使用如下命令开启一个HTTP服务:
Then we can use it to profile `main.py.prof` generated in the previous
section:
```bash
pprof -http=0.0.0.0:3213 `which python` ./main.py.prof
```
这行命令中,`-http`指开启HTTP服务。`which python`会产生当前Python二进制的完整路径,进而指定了Python可执行文件的路径。`./main.py.prof`输入了性能分析结果。
访问对应的网址,我们可以查看性能分析的结果。结果如下图所示:
Where `-http` specifies the IP and port of the HTTP service.
Directing our Web browser to the service, we would see something like
the following:
![result](./pprof_1.png)
### Identifying the Performance Bottlenecks
### 寻找性能瓶颈
与寻找Python代码的性能瓶颈类似,寻找Python与C++混合代码的性能瓶颈也是要看`tottime``cumtime`。而`pprof`展示的调用图也可以帮助我们发现性能中的问题。
例如下图中,
Similar to how we work with `cprofilev`, we'd focus on `tottime` and
`cumtime`.
![kernel_perf](./pprof_2.png)
在一次训练中,乘法和乘法梯度的计算占用2%-4%左右的计算时间。而`MomentumOp`占用了17%左右的计算时间。显然,`MomentumOp`的性能有问题。
`pprof`中,对于性能的关键路径都做出了红色标记。先检查关键路径的性能问题,再检查其他部分的性能问题,可以更有次序的完成性能的优化。
## 总结
We can see that the execution time of multiplication and the computing
of the gradient of multiplication takes 2% to 4% of the total running
time, and `MomentumOp` takes about 17%. Obviously, we'd want to
optimize `MomentumOp`.
至此,两种性能分析的方式都介绍完毕了。希望通过这两种性能分析的方式,Paddle的开发人员和使用人员可以有次序的,科学的发现和解决性能问题。
`pprof` would mark performance critical parts of the program in
red. It's a good idea to follow the hints.
此教程会介绍如何使用Python的cProfile包、Python库yep、Google perftools来进行性能分析 (profiling) 与调优(performance tuning)。
Profling 指发现性能瓶颈。系统中的瓶颈可能和程序员开发过程中想象的瓶颈相去甚远。Tuning 指消除瓶颈。性能优化的过程通常是不断重复地 profiling 和 tuning。
PaddlePaddle 用户一般通过调用 Python API 编写深度学习程序。大部分 Python API 调用用 C++ 写的 libpaddle.so。所以 PaddlePaddle 的性能分析与调优分为两个部分:
* Python 代码的性能分析
* Python 与 C++ 混合代码的性能分析
## Python代码的性能分析
### 生成性能分析文件
Python标准库中提供了性能分析的工具包,[cProfile](https://docs.python.org/2/library/profile.html)。生成Python性能分析的命令如下:
```bash
python -m cProfile -o profile.out main.py
```
其中 `main.py` 是我们要分析的程序,`-o`标识了一个输出的文件名,用来存储本次性能分析的结果。如果不指定这个文件,`cProfile`会打印到标准输出。
### 查看性能分析文件
`cProfile` 在main.py 运行完毕后输出`profile.out`。我们可以使用[`cprofilev`](https://github.com/ymichael/cprofilev)来查看性能分析结果。`cprofilev`是一个Python的第三方库。使用它会开启一个HTTP服务,将性能分析结果以网页的形式展示出来:
```bash
cprofilev -a 0.0.0.0 -p 3214 -f profile.out main.py
```
其中`-a`标识HTTP服务绑定的IP。使用`0.0.0.0`允许外网访问这个HTTP服务。`-p`标识HTTP服务的端口。`-f`标识性能分析的结果文件。`main.py`标识被性能分析的源文件。
用Web浏览器访问对应网址,即可显示性能分析的结果:

LogLoss Operator.
Log loss is a loss function used for binary classification. Log Loss quantifies
the accuracy of a classifier by penalising false classifications. Minimising the
Log Loss is equivalent to maximising the accuracy of the classifier. We define
Predicted as the values predicted by our model and Labels as the target ground
truth value. Log loss can evaluate how close the predicted values are to the
target. The shapes of Predicted and Labels are both [batch_size, 1].
The equation is:
$$
Loss = - Labels * log(Predicted + \epsilon) -
(1 - Labels) * log(1 - Predicted + \epsilon)
