We start from considering our daily development environment. +### Official Docker Releases -Developers work on a computer, which is usually a laptop or desktop: +Official docker images at +[here](https://hub.docker.com/r/paddlepaddle/paddle/tags/), +you can choose either latest or images with a release tag like `0.10.0`, +Currently available tags are: - +| Tag | Description | +| ------ | --------------------- | +| latest | latest CPU only image | +| latest-gpu | latest binary with GPU support | +| 0.10.0 | release 0.10.0 CPU only binary image | +| 0.10.0-gpu | release 0.10.0 with GPU support | -or, they might rely on a more sophisticated box (like with GPUs): +### Build Your Own Image - +Build PaddlePaddle docker images are quite simple since PaddlePaddle can +be installed by just running `pip install`. A sample `Dockerfile` is: -A principle here is that source code lies on the development computer (host) so that editors like Eclipse can parse the source code to support auto-completion. +```dockerfile +FROM nvidia/cuda:7.5-cudnn5-runtime-centos6 +RUN yum install -y centos-release-SCL +RUN yum install -y python27 +# This whl package is generated by previous build steps. +ADD python/dist/paddlepaddle-0.10.0-cp27-cp27mu-linux_x86_64.whl / +RUN pip install /paddlepaddle-0.10.0-cp27-cp27mu-linux_x86_64.whl && rm -f /*.whl +``` +Then build the image by running `docker build -t [REPO]/paddle:[TAG] .` under +the directory containing your own `Dockerfile`. -## Usages +- NOTE: note that you can choose different base images for your environment, you can find all the versions [here](https://hub.docker.com/r/nvidia/cuda/). -### Build the Development Docker Image +### Use Docker Images -The following commands check out the source code to the host and build the development image `paddle:dev`: +Suppose that you have written an application program `train.py` using +PaddlePaddle, we can test and run it using docker: ```bash -git clone https://github.com/PaddlePaddle/Paddle paddle -cd paddle -docker build -t paddle:dev . +docker run --rm -it -v $PWD:/work paddlepaddle/paddle /work/a.py ``` -The `docker build` command assumes that `Dockerfile` is in the root source tree. Note that in this design, this `Dockerfile` is this only one in our repo. - -Users can specify a Ubuntu mirror server for faster downloading: - -```bash -docker build -t paddle:dev --build-arg UBUNTU_MIRROR=mirror://mirrors.ubuntu.com/mirrors.txt . -``` +But this works only if all dependencies of `train.py` are in the production image. If this is not the case, we need to build a new Docker image from the production image and with more dependencies installs. -### Build PaddlePaddle from Source Code +### Run PaddlePaddle Book In Docker -Given the development image `paddle:dev`, the following command builds PaddlePaddle from the source tree on the development computer (host): +Our [book repo](https://github.com/paddlepaddle/book) also provide a docker +image to start a jupiter notebook inside docker so that you can run this book +using docker: ```bash -docker run --rm -v $PWD:/paddle -e "WITH_GPU=OFF" -e "WITH_AVX=ON" -e "WITH_TESTING=OFF" -e "RUN_TEST=OFF" paddle:dev +docker run -d -p 8888:8888 paddlepaddle/book ``` -This command mounts the source directory on the host into `/paddle` in the container, so the default entry point of `paddle:dev`, `build.sh`, could build the source code with possible local changes. When it writes to `/paddle/build` in the container, it writes to `$PWD/build` on the host indeed. - -`build.sh` builds the following: - -- PaddlePaddle binaries, -- `$PWD/build/paddle-.deb` for production installation, and -- `$PWD/build/Dockerfile`, which builds the production Docker image. +Please refer to https://github.com/paddlepaddle/book if you want to build this +docker image by your self. -Users can specify the following Docker build arguments with either "ON" or "OFF" value: -- `WITH_GPU`: ***Required***. Generates NVIDIA CUDA GPU code and relies on CUDA libraries. -- `WITH_AVX`: ***Required***. Set to "OFF" prevents from generating AVX instructions. If you don't know what is AVX, you might want to set "ON". -- `WITH_TEST`: ***Optional, default OFF***. Build unit tests binaries. Once you've built the unit tests, you can run these test manually by the following command: - ```bash - docker run --rm -v $PWD:/paddle -e "WITH_GPU=OFF" -e "WITH_AVX=ON" paddle:dev sh -c "cd /paddle/build; make coverall" - ``` -- `RUN_TEST`: ***Optional, default OFF***. Run unit tests after building. You can't run unit tests without building it. +### Run Distributed Applications -### Build the Production Docker Image +In our [API design doc](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/design/api.md#distributed-training), we proposed an API that starts a distributed training job on a cluster. This API need to build a PaddlePaddle application into a Docker image as above and calls kubectl to run it on the cluster. This API might need to generate a Dockerfile look like above and call `docker build`. -The following command builds the production image: +Of course, we can manually build an application image and launch the job using the kubectl tool: ```bash -docker build -t paddle -f build/Dockerfile ./build +docker build -f some/Dockerfile -t myapp . +docker tag myapp me/myapp +docker push +kubectl ... ``` -This production image is minimal -- it includes binary `paddle`, the shared library `libpaddle.so`, and Python runtime. +## Docker Images for Developers -### Run PaddlePaddle Applications +We have a special docker image for developers: +`paddlepaddle/paddle:-dev`. This image is also generated from +https://github.com/PaddlePaddle/buildtools -Again the development happens on the host. Suppose that we have a simple application program in `a.py`, we can test and run it using the production image: +This a development image contains only the +development tools and standardizes the building procedure. Users include: -```bash -docker run --rm -it -v $PWD:/work paddle /work/a.py -``` +- developers -- no longer need to install development tools on the host, and can build their current work on the host (development computer). +- release engineers -- use this to build the official release from certain branch/tag on Github.com. +- document writers / Website developers -- Our documents are in the source repo in the form of .md/.rst files and comments in source code. We need tools to extract the information, typeset, and generate Web pages. -But this works only if all dependencies of `a.py` are in the production image. If this is not the case, we need to build a new Docker image from the production image and with more dependencies installs. +Of course, developers can install building tools on their development computers. But different versions of PaddlePaddle might require different set or version of building tools. Also, it makes collaborative debugging easier if all developers use a unified development environment. -### Build and Run PaddlePaddle Applications +The development image contains the following tools: -We need a Dockerfile in https://github.com/paddlepaddle/book that builds Docker image `paddlepaddle/book:`, basing on the PaddlePaddle production image: + - gcc/clang + - nvcc + - Python + - sphinx + - woboq + - sshd -``` -FROM paddlepaddle/paddle: -RUN pip install -U matplotlib jupyter ... -COPY . /book -EXPOSE 8080 -CMD ["jupyter"] -``` +Many developers work on a remote computer with GPU; they could ssh into the computer and `docker exec` into the development container. However, running `sshd` in the container allows developers to ssh into the container directly. -The book image is an example of PaddlePaddle application image. We can build it -```bash -git clone https://github.com/paddlepaddle/book -cd book -docker build -t book . -``` +### Development Workflow -### Build and Run Distributed Applications +Here we describe how the workflow goes on. We start from considering our daily development environment. -In our [API design doc](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/design/api.md#distributed-training), we proposed an API that starts a distributed training job on a cluster. This API need to build a PaddlePaddle application into a Docker image as above and calls kubectl to run it on the cluster.

 and , which are strings
-#        you would put in $PS1 before and after the status string
-#        generated by the git-prompt machinery.  e.g.
-#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
-#          will show username, at-sign, host, colon, cwd, then
-#          various status string, followed by dollar and SP, as
-#          your prompt.
-#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
-#          will show username, pipe, then various status string,
-#          followed by colon, cwd, dollar and SP, as your prompt.
-#        Optionally, you can supply a third argument with a printf
-#        format string to finetune the output of the branch status
-#
-# The repository status will be displayed only if you are currently in a
-# git repository. The %s token is the placeholder for the shown status.
-#
-# The prompt status always includes the current branch name.
-#
-# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
-# unstaged (*) and staged (+) changes will be shown next to the branch
-# name.  You can configure this per-repository with the
-# bash.showDirtyState variable, which defaults to true once
-# GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-# You can also see if currently something is stashed, by setting
-# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-# then a '$' will be shown next to the branch name.
-#
-# If you would like to see if there're untracked files, then you can set
-# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
-# files, then a '%' will be shown next to the branch name.  You can
-# configure this per-repository with the bash.showUntrackedFiles
-# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
-# enabled.
-#
-# If you would like to see the difference between HEAD and its upstream,
-# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
-# indicates you are ahead, "<>" indicates you have diverged and "="
-# indicates that there is no difference. You can further control
-# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
-# of values:
-#
-#     verbose       show number of commits ahead/behind (+/-) upstream
-#     legacy        don't use the '--count' option available in recent
-#                   versions of git-rev-list
-#     git           always compare HEAD to @{upstream}
-#     svn           always compare HEAD to your SVN upstream
-#
-# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
-# find one, or @{upstream} otherwise.  Once you have set
-# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
-# setting the bash.showUpstream config variable.
-#
-# If you would like to see more information about the identity of
-# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
-# to one of these values:
-#
-#     contains      relative to newer annotated tag (v1.6.3.2~35)
-#     branch        relative to newer tag or branch (master~4)
-#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
-#     default       exactly matching tag
-#
-# If you would like a colored hint about the current dirty state, set
-# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
-# the colored output of "git status -sb" and are available only when
-# using __git_ps1 for PROMPT_COMMAND or precmd.

+#
+# Copyright (C) 2006,2007 Shawn O. Pearce

+#
+# This script allows you to see repository status in your prompt.
+#
+# To enable:
+#
+#    1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
+#    2) Add the following line to your .bashrc/.zshrc:
+#        source ~/.git-prompt.sh
+#    3a) Change your PS1 to call __git_ps1 as
+#        command-substitution:
+#        Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
+#        ZSH:  setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
+#        the optional argument will be used as format string.
+#    3b) Alternatively, for a slightly faster prompt, __git_ps1 can
+#        be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
+#        with two parameters, 
 and , which are strings
+#        you would put in $PS1 before and after the status string
+#        generated by the git-prompt machinery.  e.g.
+#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
+#          will show username, at-sign, host, colon, cwd, then
+#          various status string, followed by dollar and SP, as
+#          your prompt.
+#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
+#          will show username, pipe, then various status string,
+#          followed by colon, cwd, dollar and SP, as your prompt.
+#        Optionally, you can supply a third argument with a printf
+#        format string to finetune the output of the branch status
+#
+# The repository status will be displayed only if you are currently in a
+# git repository. The %s token is the placeholder for the shown status.
+#
+# The prompt status always includes the current branch name.
+#
+# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
+# unstaged (*) and staged (+) changes will be shown next to the branch
+# name.  You can configure this per-repository with the
+# bash.showDirtyState variable, which defaults to true once
+# GIT_PS1_SHOWDIRTYSTATE is enabled.
+#
+# You can also see if currently something is stashed, by setting
+# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
+# then a '$' will be shown next to the branch name.
+#
+# If you would like to see if there're untracked files, then you can set
+# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
+# files, then a '%' will be shown next to the branch name.  You can
+# configure this per-repository with the bash.showUntrackedFiles
+# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
+# enabled.
+#
+# If you would like to see the difference between HEAD and its upstream,
+# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
+# indicates you are ahead, "<>" indicates you have diverged and "="
+# indicates that there is no difference. You can further control
+# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
+# of values:
+#
+#     verbose       show number of commits ahead/behind (+/-) upstream
+#     legacy        don't use the '--count' option available in recent
+#                   versions of git-rev-list
+#     git           always compare HEAD to @{upstream}
+#     svn           always compare HEAD to your SVN upstream
+#
+# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
+# find one, or @{upstream} otherwise.  Once you have set
+# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
+# setting the bash.showUpstream config variable.
+#
+# If you would like to see more information about the identity of
+# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
+# to one of these values:
+#
+#     contains      relative to newer annotated tag (v1.6.3.2~35)
+#     branch        relative to newer tag or branch (master~4)
+#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
+#     default       exactly matching tag
+#
+# If you would like a colored hint about the current dirty state, set
+# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
+# the colored output of "git status -sb" and are available only when
+# using __git_ps1 for PROMPT_COMMAND or precmd.

Subject: [PATCH 64/96] Simpily demo, add paddle.default_main_program() and
 paddle.default_startup_program

- Removed all main_program and startup_program in the demo.
- Using paddle.default_main_program() hides the implementation detail (e.g., using g_main_program) from the user, we can change the implementation in the future much easier.

+ * This is an implementation of beam search.
+ *
+ * To explain the details, lets take machine translation task for example, in
+ * this task, one source sentence is translated to multiple target sentences,
+ * during this period, one sentence will be translated to multiple translation
+ * prefixes(target sentence that have not ended), in each time step a prefix
+ * will have some candidates, input the candidate ids and their corresponding
+ * scores (probabilities), it will sort and select the top beam_size candidates
+ * for each source sentence, and store the selected candidates's score and their
+ * corresponding ids to LoDTensors.
+ *
+ * A detailed example:
+ *
+ * Input
+ *
+ * ids:
+ * LoD (should have 2 levels)
+ * first level: [0, 1, 4]
+ * second level: [0, 1, 2, 3, 4]
+ *
+ * tensor's data
+ * [
+ * [4, 2, 5]
+ * [2, 1, 3]
+ * [3, 5, 2]
+ * [8, 2, 1]
+ * ]
+ *
+ * scores:
+ * LoD same as `ids`
+ * tensor's data
+ * [
+ * [0.5, 0.3, 0.2]
+ * [0.6, 0.3, 0.1]
+ * [0.9, 0.5, 0.1]
+ * [0.7, 0.5, 0.1]
+ * ]
+ *
+ * the inputs means that there are 2 source sentences to translate, and the
+ * first source has 1 prefix, the second source has 2 prefix.
+ *
+ * lets assume beam size is 2, and the beam search's output should be
+ * LoD
+ * first level:
+ * [0, 1, 2]
+ * second level:
+ * [0, 2, 4]
+ *
+ * tensor's data
+ * [[
+ * 0.5,
+ * 0.3,
+ * 0.9,
+ * 0.7
+ * ]]
+ *
+ * TODO all the prune operations should be in the beam search, so it is better
+ * to split the beam search algorithm into a sequence of smaller operators, and
+ * the prune operators can be inserted in this sequence.

 # Region-based Heterogeneous Memory Management
+## Design
 
-Please check out the [design documentation](http://gangliao.me) to find out more details about
-buddy memory allocator for both CPU and GPU.
+### Usage
+
+To allocate 4KB CPU memory:
+
+```cpp
+p = memory::Alloc(platform::CPUPlace(), 4*1024);
+```
+
+To allocate 4KB memory on the 3rd GPU:
+
+```cpp
+p = memory::Alloc(platform::GPUPlace(2), 4*1024);
+```
+
+To free memory and check the so-far used amount of memory on a place:
+
+```cpp
+auto pl = platform::GPUPlace(0);
+p = memory::Alloc(pl, 4*1024);
+cout << memory::Used(pl);
+memory::Free(pl, p);
+```
+
+### API
+
+In `paddle/memory/memory.h` we have:
+
+```cpp
+namespace memory {
+template  void* Alloc(Place, size_t);
+template  void Free(Place, void*);
+template  size_t Used(Place);
+}  // namespace memory
+```
+
+These function templates have specializations on either `platform::CPUPlace` or `platform::GPUPlace`:
+
+```cpp
+template<>
+void* Alloc(CPUPlace p, size_t size) {
+  return GetCPUBuddyAllocator()->Alloc(size);
+}
+```
+
+and 
+
+```cpp
+template<>
+void Alloc(GPUPlace p, size_t size) {
+  return GetGPUBuddyAllocator(p.id)->Alloc(size);
+}
+```
+
+Similar specializations exist for `Free` and `Used`.
+
+### Implementation
+
+`GetCPUBuddyAllocator` and `GetGPUBuddyAllocator` are singletions.
+
+```cpp
+BuddyAllocator* GetCPUBuddyAllocator() {
+  static BuddyAllocator* a = NULL;
+  if (a == NULL) {
+    a = new BuddyAllocator(new CPUAllocator /*backup allocator*/, ...);
+  }
+  return a;
+}
+
+BuddyAllocator* GetGPUBuddyAllocator(int gpu_id) {
+  static BuddyAllocator* as = NULL;
+  if (as == NULL) {
+    as = new BuddyAllocator*[platform::NumGPUs()];
+    for (int gpu = 0; gpu < platform::NumGPUs(); gpu++) {
+      as[gpu] = new BuddyAllocator(new GPUAllocator(gpu) /* backup allocator */, ...);
+    }
+  }
+  return as[gpu_id);
+```
+
+#### `BuddyAllocator`
+
+`BuddyAllocator` implements the buddy allocation algorithm.  Its constructor takes parameters only related with the algorithm:
+
+```cpp
+BuddyAllocator::BuddyAllocator(initial_pool_size, max_pool_size) {
+  ...
+}
+```
+
+Please be aware that **`BuddyAllocator` always allocate aligned memory**, aligned on 32-bytes, which can hold a `BuddyAllocator::Block` object:
+
+```cpp
+class BuddyAllocator {
+ private:
+  struct Block {
+    size_t size;
+    Block* left, right;
+    size_t index; // allocator id
+  };
+  ...
+};
+```
+
+Because BuddyAllocator has the meta-data of each block, it can trace the used memory -- record the amount returned by `Alloc` freed in `Free`.  Instead, `CPUAllocator` and `GPUAllocator` doesn't know the size of freed memory block and cannot do the trace.
+
+#### System Allocators
+
+The `GPUAllocator` and `CPUAllocator` are calls *system allocators*.  They work as the fallback allocators of `BuddyAllocator`.
+
+## Justification
+
+I got inspiration from Majel and Caffe2, though above design look different from both.
+
+### Caffe2
+
+In Caffe2, `Tensor::mutable_data()` allocates the memroy.  In particular, [`Tensor::mutable_data`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/tensor.h#L523) calls [`Tensor::raw_mutable_data`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/tensor.h#L459), which in turn calls [`Context::New`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/tensor.h#L479).
+
+There are two implementations of `Context`:
+
+1. [`CPUContext`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/context.h#L105), whose [`New` method](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/context.h#L131) calls [`g_cpu_allocator.get()->New(size_t)`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/context.cc#L15) to allocate the memory.
+
+1. [`CUDAContext`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/context_gpu.h#L99), which has a data member [`int gpu_id_`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/context_gpu.h#L202).  This looks very similar to class `majel::GPUPlace`, who also has an `int id_` data member.   `CUDAContext::New(size_t)` calls [`g_cub_allocator->DeviceAllocate(&ptr, nbytes)`](https://github.com/caffe2/caffe2/blob/v0.7.0/caffe2/core/context_gpu.cu#L355) to allocate the memory.
+
+### Majel
+
+In Majel, there are basically two allocator types:
+
+1. `cpu::SystemAllocator`, which has similar functionality to `caffe2::CPUContext::New/Delete`.
+1. `gpu::SystemAllocator`, which has similar functionality to `caffe2::CUDAContext::New/Delete`.
+
+However, memory allocation is not via these two allocators.  Instead, these two allocators are defined in hidden namespaces.
+
+In Majel there are hidden global variables like:
+
+1. `cpu::SystemAllocator g_cpu_allocator`, and
+1. `vector g_gpu_allocators(NUM_GPUS)`.
+
+Programs allocate memory via a BuddyAllocator, which can take the `g_cpu_allocator` or a `g_gpu_allocators[gpu_id]` as its *fallback allocator*, so that if BuddyAllocator cannot find a block in its memory pool, it extends its memory pool by calling the fallback allocator's `New(size_t)`.
