-------------------------------------
Why do I need this?
-------------------------------------
===================
To make our lives easier and bring Composable Kernel dependencies together, we recommend using
docker images that can be found on `Docker Hub <https://hub.docker.com/r/rocm/composable_kernel>`_.
To make things simpler, and bring Composable Kernel and its dependencies together,
docker images can be found on `Docker Hub <https://hub.docker.com/r/rocm/composable_kernel/tags>`_. Docker images provide a complete image of the OS, the Composable Kernel library, and its dependencies in a single downloadable file.
-------------------------------------
So what is Composable Kernel?
-------------------------------------
Refer to `Docker Overview <https://docs.docker.com/get-started/overview/>`_ for more information on Docker images and containers.
Composable Kernel (CK) library aims to provide a programming model for writing performance critical
kernels for machine learning workloads across multiple architectures including GPUs, CPUs, etc,
through general purpose kernel languages, like HIP C++.
Which image is right for me?
============================
To get the CK library::
The image naming includes information related to the docker image.
For example ``ck_ub20.04_rocm6.0`` indicates the following:
git clone https://github.com/ROCmSoftwarePlatform/composable_kernel.git
* ``ck`` - made for running Composable Kernel;
* ``ub20.04`` - based on Ubuntu 20.04;
* ``rocm6.0`` - ROCm platform version 6.0.
Download a docker image suitable for your OS and ROCm release, run or start the docker container, and then resume the tutorial from this point. Use the ``docker pull`` command to download the file::
docker pull rocm/composable_kernel:ck_ub20.04_rocm6.0
run a docker container::
What is inside the image?
-------------------------
The docker images have everything you need for running CK including:
* `ROCm <https://www.amd.com/en/graphics/servers-solutions-rocm>`_
* `CMake <https://cmake.org/getting-started/>`_
* `Compiler <https://github.com/RadeonOpenCompute/llvm-project>`_
* `Composable Kernel library <https://github.com/ROCm/composable_kernel>`_
Running the docker container
============================
After downloading the docker image, you can start the container using one of a number of commands. Start with the ``docker run`` command as shown below::
docker run \

.. note::
and::
If your current folder is different from `${HOME}`, adjust the line ``-v ${HOME}:/root/workspace`` in the ``docker run`` command to fit your folder structure.
make -j examples tests
Stop and restart the docker image
=================================
To run all the test cases including tests and examples run::
After finishing the tutorial, or just when you have completed your work session, you can close the docker container, or stop the docker container to restart it at another time. Closing the docker container means that it is still in the active state, and can be resumed from where you left it. Stopping the container closes it, and returns the image to its initial state.
make test
Use the ``Ctrl-D`` option to exit the container, while leaving it active, so you can return to the container in its current state to resume the tutorial, or pickup your project where you left off.
We can also run specific examples or tests like::
To restart the active container use the ``docker exec`` command to specify the container name and options as follows::
./bin/example_gemm_xdl_fp16
./bin/test_gemm_fp16
docker exec -it <container_name> bash
For more details visit `CK github repository <https://github.com/ROCmSoftwarePlatform/composable_kernel>`_,
`CK examples <https://github.com/ROCmSoftwarePlatform/composable_kernel/tree/develop/example)>`_,

And what is inside?
-------------------------------------
* `exec` is the docker command
* `-it` is the interactive option for `exec`
* `<container_name>` specifies an active container on the system
* `bash` specifies the command to run in the interactive shell
The docker images have everything you need for running CK including:
.. note::
* `ROCm <https://www.amd.com/en/graphics/servers-solutions-rocm>`_
* `CMake <https://cmake.org/>`_
* `Compiler <https://github.com/RadeonOpenCompute/llvm-project>`_
You can use the ``docker container ls`` command to list the active containers on the system.
-------------------------------------
Which image is right for me?
-------------------------------------
To start a container from the image, use the ``docker start`` command::
Let's take a look at the image naming, for example ``ck_ub20.04_rocm5.6``. The image specs are:
docker start <container_name>
* ``ck`` - made for running Composable Kernel;
* ``ub20.04`` - based on Ubuntu 20.04;
* ``rocm5.6`` - ROCm platform version 5.6.
Then use the docker exec command as shown above to start the bash shell.
So just pick the right image for your project dependencies and you're all set.
Use the ``docker stop`` command to stop the container and restore the image to its initial state::

docker stop <container_name>

This tutorial is aimed at engineers dealing with artificial intelligence and machine learning who
would like to optimize their pipelines and squeeze every performance drop by adding Composable
Kernel (CK) library to their projects. We would like to make the CK library approachable so
the tutorial is not based on the latest release and doesn't have all the bleeding edge features,
but it will be reproducible now and forever.

Description
-------------------------------------
===========
Modern AI technology solves more and more problems in all imaginable fields, but crafting fast and
efficient workflows is still challenging. CK is one of the tools to make AI heavy lifting as fast
and efficient as possible. CK is a collection of optimized AI operator kernels and tools to create
new ones. The library has components required for majority of modern neural networks architectures
including matrix multiplication, convolution, contraction, reduction, attention modules, variety of
activation functions, fused operators and many more.

Build the library
-------------------------------------
=================
First let's clone the library and rebase to the tested version::
This tutorial is based on the use of docker images as explained in :ref:`docker-hub`. Download a docker image suitable for your OS and ROCm release, run or start the docker container, and then resume the tutorial from this point.
git clone https://github.com/ROCmSoftwarePlatform/composable_kernel.git
cd composable_kernel/
git checkout tutorial_hello_world
To make our lives easier we prepared
`docker images <https://hub.docker.com/r/rocm/composable_kernel>`_ with all the necessary
dependencies. Pick the right image and create a container. In this tutorial we use
``rocm/composable_kernel:ck_ub20.04_rocm5.6`` image, it is based on Ubuntu 20.04 and
ROCm v5.6.
If your current folder is ``${HOME}``, start the docker container with::
docker run \
-it \
--privileged \
--group-add sudo \
-w /root/workspace \
-v ${HOME}:/root/workspace \
rocm/composable_kernel:ck_ub20.04_rocm5.6 \
/bin/bash
.. note::
If your current folder is different from ``${HOME}``, adjust the line ``-v ${HOME}:/root/workspace``
to fit your folder structure.
You can also `install ROCm <https://rocm.docs.amd.com/projects/install-on-linux/en/latest/>`_ on your system, clone the `Composable Kernel repository <https://github.com/ROCmSoftwarePlatform/composable_kernel.git>`_ on GitHub, and use that to build and run the examples using the commands described below.
Inside the docker container current folder is ``~/workspace``, library path is
``~/workspace/composable_kernel``, navigate to the library::
Both the docker container and GitHub repository include the Composable Kernel library. Navigate to the library::
cd composable_kernel/
Create and go to the ``build`` directory::
Create and change to a ``build`` directory::
mkdir build && cd build

********************************************************************
What is the Composable Kernel library
********************************************************************
Methodology
===========
The Composable Kernel (CK) library provides a programming model for writing performance critical kernels for machine learning workloads across multiple architectures including GPUs and CPUs, through general purpose kernel languages like HIP C++.
CK utilizes two concepts to achieve performance portability and code maintainability:
* A tile-based programming model
* Algorithm complexity reduction for complex ML operators using an innovative technique called
"Tensor Coordinate Transformation".
.. image:: data/ck_component.png
:alt: CK Components
Code Structure
==============
The CK library is structured into 4 layers:
* "Templated Tile Operators" layer
* "Templated Kernel and Invoker" layer
* "Instantiated Kernel and Invoker" layer
* "Client API" layer
It also includes a simple wrapper component used to perform tensor transform operations more easily and with fewer lines of code.

********************************************************************
Wrapper
********************************************************************
-------------------------------------
Description
-------------------------------------
.. note::
The wrapper is under development and its functionality is limited.
The CK library provides a lightweight wrapper for more complex operations implemented in
the library.
Example:
.. code-block:: c
const auto shape_4x2x4 = ck::make_tuple(4, ck::make_tuple(2, 4));
const auto strides_s2x1x8 = ck::make_tuple(2, ck::make_tuple(1, 8));
const auto layout = ck::wrapper::make_layout(shape_4x2x4, strides_s2x1x8);
std::array<ck::index_t, 32> data;
auto tensor = ck::wrapper::make_tensor<ck::wrapper::MemoryTypeEnum::Generic>(&data[0], layout);
for(ck::index_t w = 0; w < size(tensor); w++) {
tensor(w) = w;
}
// slice() == slice(0, -1) (whole dimension)
auto tensor_slice = tensor(ck::wrapper::slice(1, 3), ck::make_tuple(ck::wrapper::slice(), ck::wrapper::slice()));
std::cout << "dims:2,(2,4) strides:2,(1,8)" << std::endl;
for(ck::index_t h = 0; h < ck::wrapper::size<0>(tensor_slice); h++)
{
for(ck::index_t w = 0; w < ck::wrapper::size<1>(tensor_slice); w++)
{
std::cout << tensor_slice(h, w) << " ";
}
std::cout << std::endl;
}
Output::
dims:2,(2,4) strides:2,(1,8)
1 5 9 13 17 21 25 29
2 6 10 14 18 22 26 30
