# Executor Design Doc
## Motivation
+In [fluid](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/design/fluid.md), we encourage the user to use deep learning programming paradigms to describe the training process. When the user-written Python program is executed, it will first create a protobuf message
+[`ProgramDesc`](https://github.com/PaddlePaddle/Paddle/blob/a91efdde6910ce92a78e3aa7157412c4c88d9ee8/paddle/framework/framework.proto#L145) that describes the process and is conceptually like an [abstract syntax tree](https://en.wikipedia.org/wiki/Abstract_syntax_tree).
-We use executor to do the runtime evaluation of a `ProgramDesc`.
+The executor runs the `ProgramDesc` like an interpreter. `ProgramDesc` contains the intrinsics (operators in this case) and variables which will be used, executor explicitly executes the stored precompiled code.
## Overview
-An executor takes a `ProgramDesc`, a `block_id` and a `Scope`. The `ProgramDesc` is a list of blocks and each block contains the protobuf definition of all the parameters and operators. The `block_id` specifies the entrance block. And the `Scope` is the container of all the variable instance, which is persistent throughout different runs.
+An executor takes a `ProgramDesc`, a `block_id` and a `Scope`. The `ProgramDesc` is a list of blocks and each block contains the protobuf definition of all the parameters and operators in the block. The `block_id` specifies the entrance block. And the `Scope` is the container of all the variable instances, which is persistent throughout different runs.
-### What does executor do?
+## Executor
-It evaluates all the operators in the `block_id`th block of a `ProgramDesc`.
+The `Executor` explicitly executes all the intrinsics (operators here) in the `block_id`th block of a `ProgramDesc`. Essentially, it instantiates Variables and Operators, then runs all the operators in sequence one-by-one.
+It is very similar to how a push stack frame works when entering a block, following which it cleans up all the temporary variables when a mini-batch is finished. It does not however, have the stack frame pop process.
-### What does executor NOT do?
+### The interface
+```c++
+ Executor(places);
+```
+A executor does not own any computing resources, a user can only construct an executor using the specified places.
-It does not do runtime optimization, meaning intelligently parse the dependency of each op a choose which one to be run and in which order they should be run.
+### Running an Executor
-It does not do graph partitioning, meaning dividing the `ProgramDesc` into several small pieces and executing them on different devices.
-
-## Implementation
-
-`Executor` evaluates a `ProgramDesc`. Essentially, it instantiates Variables and Operators, then run all the operators in sequence. [[code]](https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/framework/executor.cc)
+```
+ void Run(ProgramDesc, Scope, block_id, create_local_scope);
+```
+An `Executor` only provides a unified way to execute `ProgramDesc`. `ProgramDesc` is the target that will be executed, the `Scope` specifies the variable container, the `block_id` indicates the entrance block and `create_local_scope` is a boolean that states whether it will destroy the temporary variables after the execution is finished.

在使用同步SGD训练神经网络时，PaddlePaddle使用同步屏障（barrier），使梯度的提交和参数的更新按照顺序方式执行。在异步SGD中，则并不会等待所有trainer提交梯度才更新参数，这样极大地提高了计算的并行性：参数服务器之间不相互依赖，并行地接收梯度和更新参数，参数服务器也不会等待计算节点全部都提交梯度之后才开始下一步，计算节点之间也不会相互依赖，并行地执行模型的训练。可以看出，虽然异步SGD方式会提高参数更新并行度, 但是并不能保证参数同步更新，在任意时间某一台参数服务器上保存的参数可能比另一台要更新，与同步SGD相比，梯度会有噪声。
+
## 环境准备
1. 准备您的计算集群。计算集群通常由一组（几台到几千台规模）的Linux服务器组成。服务器之间可以通过局域网（LAN）联通，每台服务器具有集群中唯一的IP地址（或者可被DNS解析的主机名）。集群中的每台计算机通常被成为一个“节点”。
-1. 我们需要在集群的所有节点上安装 PaddlePaddle。 如果要启用GPU，还需要在节点上安装对应的GPU驱动以及CUDA。PaddlePaddle的安装可以参考[build_and_install](https://github.com/PaddlePaddle/Paddle/tree/develop/doc/getstarted/build_and_install)的多种安装方式。我们推荐使用[Docker](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/getstarted/build_and_install/docker_install_cn.rst)安装方式来快速安装PaddlePaddle。

-### 使用Fabric启动集群作业
-
-#### 准备一个Linux集群
-可以在`paddle/scripts/cluster_train_v2/fabric/docker_cluster`目录下，执行`kubectl -f ssh_servers.yaml`启动一个测试集群，并使用`kubectl get po -o wide`获得这些节点的IP地址。
-
-#### 启动集群作业
-
-`paddle.py` 提供了自动化脚本来启动不同节点中的所有 PaddlePaddle 集群进程。默认情况下，所有命令行选项可以设置为 `paddle.py` 命令选项并且 `paddle.py` 将透明、自动地将这些选项应用到 PaddlePaddle 底层进程。
-
-`paddle.py` 为方便作业启动提供了两个独特的命令选项。
-
-- `job_dispatch_package` 设为本地 `workspace` 目录，它将被分发到 `conf.py` 中设置的所有节点。它有助于帮助频繁修改和访问工作区文件的用户减少负担，否则频繁的多节点工作空间部署可能会很麻烦。
-- `job_workspace` 设为已部署的工作空间目录，`paddle.py` 将跳过分发阶段直接启动所有节点的集群作业。它可以帮助减少分发延迟。
-
-`cluster_train/run.sh` 提供了命令样例来运行 `doc/howto/usage/cluster/src/word2vec` 集群任务，只需用您定义的目录修改 `job_dispatch_package` 和 `job_workspace`，然后：
-```
-sh run.sh
-```
-
-集群作业将会在几秒后启动。
-
-#### 终止集群作业
-`paddle.py`能获取`Ctrl + C` SIGINT 信号来自动终止它启动的所有进程。只需中断 `paddle.py` 任务来终止集群作业。如果程序崩溃你也可以手动终止。
-
-#### 检查集群训练结果
-详细信息请检查 $workspace/log 里的日志，每一个节点都有相同的日志结构。
-
-`paddle_trainer.INFO`
-提供几乎所有训练的内部输出日志，与本地训练相同。这里检验运行时间模型的收敛。
-
-`paddle_pserver2.INFO`
-提供 pserver 运行日志，有助于诊断分布式错误。
-
-`server.log`
-提供 parameter server 进程的 stderr 和 stdout。训练失败时可以检查错误日志。
-
-`train.log`
-提供训练过程的 stderr 和 stdout。训练失败时可以检查错误日志。
-
-#### 检查模型输出
-运行完成后，模型文件将被写入节点 0 的 `output` 目录中。
-工作空间中的 `nodefile` 表示当前集群作业的节点 ID。
-
-### 在OpenMPI集群中提交训练作业
-
-#### 准备OpenMPI集群
-
-执行下面的命令以启动3个节点的OpenMPI集群和一个"head"节点：
-
-```bash
-paddle/scripts/cluster_train_v2/openmpi/docker_cluster
-kubectl create -f head.yaml
-kubectl create -f mpi-nodes.yaml
-```
-
-然后可以从head节点ssh无密码登录到OpenMPI的每个节点上。
-
-#### 启动集群作业
-
-您可以按照下面的步骤在OpenMPI集群中提交paddle训练任务：
-
-```bash
-# 获得head和node节点的IP地址
-kubectl get po -o wide
-# 将node节点的IP地址保存到machines文件中
-kubectl get po -o wide | grep nodes | awk '{print $6}' > machines
-# 拷贝必要的文件到head节点
-scp -i ssh/id_rsa.mpi.pub machines prepare.py train.py start_mpi_train.sh tutorial@[headIP]:~
-# ssh 登录到head节点
-ssh -i ssh/id_rsa.mpi.pub tutorial@[headIP]
-# --------------- 以下操作均在head节点中执行 ---------------
-# 准备训练数据
-python prepare.py
-# 拷贝训练程序和字典文件到每台MPI节点
-cat machines | xargs -i scp word_dict.pickle train.py start_mpi_train.sh machines {}:/home/tutorial
-# 创建日志目录
-mpirun -hostfile machines -n 3 mkdir /home/tutorial/logs
-# 拷贝训练数据到各自的节点
-scp train.txt-00000 test.txt-00000 [node1IP]:/home/tutorial
-scp train.txt-00001 test.txt-00001 [node2IP]:/home/tutorial

These cluster platforms provide API or environment variables for training processes, when the job is dispatched to different nodes. Like node ID, IP or total number of nodes etc.
-### Cluster Training Using Fabric
-
-#### Prepare a Linux cluster
-
-Run `kubectl -f ssh_servers.yaml` under the directory: `paddle/scripts/cluster_train_v2/fabric/docker_cluster` will launch a demo cluster. Run `kubectl get po -o wide` to get IP addresses of these nodes.
-
-#### Launching Cluster Job
-`paddle.py` provides automatical scripts to start all PaddlePaddle cluster processes in different nodes. By default, all command line options can be set as `paddle.py` command options and `paddle.py` will transparently and automatically set these options to PaddlePaddle lower level processes.
-
-`paddle.py`provides two distinguished command option for easy job launching.
-
-- `job_dispatch_package` set it with local `workspace` directory, it will be dispatched to all nodes which is set in `conf.py`. It could be helpful for frequently manipulating workspace files. otherwise, frequent multi-nodes workspace deployment is very annoying.
-- `job_workspace` set it with already deployed workspace directory, `paddle.py` will skip dispatch stage to directly launch cluster job with all nodes. It could help to reduce heavy
-dispatch latency.
-
-`cluster_train/run.sh` provides command line sample to run `demo/recommendation` cluster job, just modify `job_dispatch_package` and `job_workspace` with your defined directory, then:
-```
-sh run.sh
-```
-
-The cluster Job will start in several seconds.
-
-#### Kill Cluster Job
-`paddle.py` can capture `Ctrl + C` SIGINT signal to automatically kill all processes launched by it. So just stop `paddle.py` to kill cluster job. You should manually kill the job if the program crashed.
-
-#### Check Cluster Training Result
-Check log in $workspace/log for details, each node owns same log structure.
-
-`paddle_trainer.INFO`
-It provides almost all internal output log for training, same as local training. Check runtime model convergence here.
-
-`paddle_pserver2.INFO`
-It provides parameter server running log, which could help to diagnose distributed error.
-
-`server.log`
-It provides stderr and stdout of parameter server process. Check error log if training crashes.
-
-`train.log`
-It provides stderr and stdout of trainer process. Check error log if training crashes.
-
-#### Check Model Output
-After one pass finished, model files will be written in `output` directory in node 0.
-`nodefile` in workspace indicates the node id of current cluster job.
-
-### Cluster Training Using OpenMPI
-
-#### Prepare an OpenMPI cluster
-
-Run the following command to start a 3-node MPI cluster and one "head" node.
-
-```bash
-cd paddle/scripts/cluster_train_v2/openmpi/docker_cluster
-kubectl create -f head.yaml
-kubectl create -f mpi-nodes.yaml
-```
-
-Then you can log in to every OpenMPI node using ssh without input any passwords.
-
-#### Launching Cluster Job
-
-Follow the steps to launch a PaddlePaddle training job in OpenMPI cluster:\
-
-```bash
-# find out node IP addresses
-kubectl get po -o wide
-# generate a "machines" file containing node IP addresses

+# 使用fabric启动集群训练
+
+## 准备一个Linux集群
+可以在`paddle/scripts/cluster_train_v2/fabric/docker_cluster`目录下，执行`kubectl -f ssh_servers.yaml`启动一个测试集群，并使用`kubectl get po -o wide`获得这些节点的IP地址。
+
+## 启动集群作业
+
+`paddle.py` 提供了自动化脚本来启动不同节点中的所有 PaddlePaddle 集群进程。默认情况下，所有命令行选项可以设置为 `paddle.py` 命令选项并且 `paddle.py` 将透明、自动地将这些选项应用到 PaddlePaddle 底层进程。
+
+`paddle.py` 为方便作业启动提供了两个独特的命令选项。
+
+- `job_dispatch_package` 设为本地 `workspace` 目录，它将被分发到 `conf.py` 中设置的所有节点。它有助于帮助频繁修改和访问工作区文件的用户减少负担，否则频繁的多节点工作空间部署可能会很麻烦。
+- `job_workspace` 设为已部署的工作空间目录，`paddle.py` 将跳过分发阶段直接启动所有节点的集群作业。它可以帮助减少分发延迟。
+
+`cluster_train/run.sh` 提供了命令样例来运行 `doc/howto/usage/cluster/src/word2vec` 集群任务，只需用您定义的目录修改 `job_dispatch_package` 和 `job_workspace`，然后：
+```
+sh run.sh
+```
+
+集群作业将会在几秒后启动。
+
+## 终止集群作业
+`paddle.py`能获取`Ctrl + C` SIGINT 信号来自动终止它启动的所有进程。只需中断 `paddle.py` 任务来终止集群作业。如果程序崩溃你也可以手动终止。
+
+## 检查集群训练结果
+详细信息请检查 $workspace/log 里的日志，每一个节点都有相同的日志结构。
+
+`paddle_trainer.INFO`
+提供几乎所有训练的内部输出日志，与本地训练相同。这里检验运行时间模型的收敛。
+
+`paddle_pserver2.INFO`
+提供 pserver 运行日志，有助于诊断分布式错误。
+
+`server.log`
+提供 parameter server 进程的 stderr 和 stdout。训练失败时可以检查错误日志。
+
+`train.log`
+提供训练过程的 stderr 和 stdout。训练失败时可以检查错误日志。
+
+## 检查模型输出
+运行完成后，模型文件将被写入节点 0 的 `output` 目录中。
+工作空间中的 `nodefile` 表示当前集群作业的节点 ID。

-# Kubernetes 简介
-
-[*Kubernetes*](http://kubernetes.io/)是Google开源的容器集群管理系统，其提供应用部署、维护、扩展机制等功能，利用Kubernetes能方便地管理跨机器运行容器化的应用。Kubernetes可以在物理机或虚拟机上运行，且支持部署到[AWS](http://kubernetes.io/docs/getting-started-guides/aws)，[Azure](http://kubernetes.io/docs/getting-started-guides/azure/)，[GCE](http://kubernetes.io/docs/getting-started-guides/gce)等多种公有云环境。介绍分布式训练之前，需要对[Kubernetes](http://kubernetes.io/)有一个基本的认识，下面先简要介绍一下本文用到的几个Kubernetes概念。
-
-- [*Node*](http://kubernetes.io/docs/admin/node/) 表示一个Kubernetes集群中的一个工作节点，这个节点可以是物理机或者虚拟机，Kubernetes集群就是由node节点与master节点组成的。
-
-- [*Pod*](http://kubernetes.io/docs/user-guide/pods/) 是一组(一个或多个)容器，pod是Kubernetes的最小调度单元，一个pod中的所有容器会被调度到同一个node上。Pod中的容器共享NET，PID，IPC，UTS等Linux namespace。由于容器之间共享NET namespace，所以它们使用同一个IP地址，可以通过*localhost*互相通信。不同pod之间可以通过IP地址访问。
-
-- [*Job*](http://kubernetes.io/docs/user-guide/jobs/) 描述Kubernetes上运行的作业，一次作业称为一个job，通常每个job包括一个或者多个pods，job启动后会创建这些pod并开始执行一个程序，等待这个程序执行成功并返回0则成功退出，如果执行失败，也可以配置不同的重试机制。
-
-- [*Volume*](http://kubernetes.io/docs/user-guide/volumes/) 存储卷，是pod内的容器都可以访问的共享目录，也是容器与node之间共享文件的方式，因为容器内的文件都是暂时存在的，当容器因为各种原因被销毁时，其内部的文件也会随之消失。通过volume，就可以将这些文件持久化存储。Kubernetes支持多种volume，例如hostPath(宿主机目录)，gcePersistentDisk，awsElasticBlockStore等。
-
-- [*Namespaces*](https://kubernetes.io/docs/user-guide/namespaces/) 命名空间，在kubernetes中创建的所有资源对象(例如上文的pod，job)等都属于一个命名空间，在同一个命名空间中，资源对象的名字是唯一的，不同空间的资源名可以重复，命名空间主要为了对象进行逻辑上的分组便于管理。本文只使用了默认命名空间。
-
-- [*PersistentVolume*](https://kubernetes.io/docs/user-guide/persistent-volumes/): 和[*PersistentVolumeClaim*](https://kubernetes.io/docs/user-guide/persistent-volumes/#persistentvolumeclaims)结合，将外部的存储服务在Kubernetes中描述成为统一的资源形式，便于存储资源管理和Pod引用。
-
-## 部署Kubernetes集群
-
-Kubernetes提供了多种集群部署的方案，本文档内不重复介绍。这里给出集中常见的部署方法：
-
-- [*minikube*](https://kubernetes.io/docs/getting-started-guides/minikube/): 快速在本地启动一个单机的kubernetes服务器，便于本地验证和测试。
-- [*kubeadm*](http://kubernetes.io/docs/getting-started-guides/kubeadm/): 在不同操作系统，不同主机(Bare-Metal, AWS, GCE)条件下，快速部署集群。
-- [*AWS EC2*](https://kubernetes.io/docs/getting-started-guides/aws/): 在aws上快速部署集群。
-- [*Bare-Metal*](https://kubernetes.io/docs/getting-started-guides/centos/centos_manual_config/): 在物理机上手动部署。
-
-可以参考[这个表格](https://kubernetes.io/docs/getting-started-guides/#table-of-solutions)选择适合您的场景的合适方案。
-
-## 选择存储方案
-
-容器不会保留在运行时生成的数据，job或者应用程序在容器中运行时生成的数据会在容器销毁时消失。为了完成分布式机器学习训练任务，需要有一个外部的存储服务来保存训练所需数据和训练输出。
-常见的可选存储服务包括：
-
-- [*NFS*](https://github.com/kubernetes/kubernetes/tree/master/examples/volumes/nfs): 可以将磁盘上某个目录共享给网络中其他机器访问。部署和配置比较简单，可以用于小量数据的验证。不提供分布式存储，高可用，冗余等功能。NFS的部署方法可以参考[这里](http://www.tecmint.com/how-to-setup-nfs-server-in-linux/)。
-- [*GlusterFS*](http://gluster.readthedocs.io/en/latest/Quick-Start-Guide/Quickstart/): 网络分布式文件系统，可以在Kubernetes中按照[这个](https://github.com/kubernetes/kubernetes/tree/master/examples/volumes/glusterfs)例子使用。
-- [*Ceph*](http://docs.ceph.com/docs/master/): 分布式文件系统，支持rbd，POSIX API接口(ceph fs)和对象存储API，参考[这里](https://kubernetes.io/docs/user-guide/volumes/#rbd)。
-- [*MooseFS*](https://moosefs.com/documentation.html): 一个分布式的存储系统。需要先挂载到服务器Node上再通过kubernetes hostPath Volume挂载到容器中。

-## 配置kubectl
-
-### 安装kubectl
-```
-# OS X
-curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl
-
-# Linux
-curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
-
-# Windows
-curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/windows/amd64/kubectl.exe
-```
-
-### 配置kubectl访问你的kubernetes集群
-
-编辑`~/.kube/config`这个配置文件，修改`Master-IP`的地址。如果使用SSL认证，则需要配置`certificate-authority`和`users`中的用户证书。如果是使用非SSL方式访问（比如通过8080端口），也可以去掉这些证书的配置。
-```
-apiVersion: v1
-clusters:
-- cluster:
- certificate-authority: /path/to/ca.crt
- server: https://[Master-IP]:443
- name: minikube
-contexts:
