Sphinx doc (#581)

* New docs directory with minimal config

* Based on docs directory of rocBLAS

* Config for running Doxygen then Sphinx to generate HTML

* Add minimal content - intro to doc

* Add some boilerplate sections to doc

* content still needs to be done,
* e.g., need to generate API documentation using Doxygen
* need to write contributor guide

* Start Softmax section of Support Primitives doc

* Written as a test bed for typesetting math content

* Need to decide how much detail to go into

* add doc directories to git ignore file.

* Minor edits - new line at EOF, change year in copyright notices

* Port Markdown files to ReStructuredText

* Copy Markdown files from pre-existing doc directory to docs directory

* Convert to reStructured Text (rst) - section headings, links, tables
  have a different syntax in rst

* New rst files added to index - can generate HTML with same style as
  HTML generated from rst files in previous commits

* Intention is to make all the content in doc redundant and use rst
  throughout rather than mix of md and rst

* Extend Softmax section of Primitives Guide

* rename l to z

* add material on applying softmax row-wise to matrix

* define macro for diag operator (represents diagonal matrix)

+==========================
+Supported Primitives Guide
+==========================
+
+This document contains details of supported primitives in Composable Kernel (CK). In contrast to the API Reference
+Guide, the Supported Primitives Guide is an introduction to the math which underpins the algorithms implemented in CK.
+
+------------
+Softmax
+------------
+
+For vectors :math:`x^{(1)}, x^{(2)}, \ldots, x^{(T)}` of size :math:`B` we can decompose the softmax of concatenated
+:math:`x = [ x^{(1)}\ | \ \ldots \ | \ x^{(T)} ]` as,
+
+.. math::
+   :nowrap:
+
+   \begin{align}
+      m(x) & = m( [ x^{(1)}\ | \ \ldots \ | \ x^{(T)} ] ) = \max( m(x^{(1)}),\ldots, m(x^{(T)}) )  \\
+      f(x) & = [\exp( m(x^{(1)}) - m(x) ) f( x^{(1)} )\ | \ \ldots \ | \ \exp( m(x^{(T)}) - m(x) ) f( x^{(T)} )] \\
+      z(x) & = \exp( m(x^{(1)}) - m(x) )\ z(x^{(1)}) + \ldots + \exp( m(x^{(T)}) - m(x) )\ z(x^{(1)}) \\
+      \operatorname{softmax}(x) &= f(x)\ / \ z(x)
+   \end{align}
+
+where :math:`f(x^{(j)}) = \exp( x^{(j)} - m(x^{(j)}) )` is of size :math:`B` and
+:math:`z(x^{(j)}) = f(x_1^{(j)})+ \ldots+ f(x_B^{(j)})` is a scalar.
+
+For a matrix :math:`X` composed of :math:`T_r \times T_c` tiles, :math:`X_{ij}`, of size :math:`B_r \times B_c` we can
+compute the row-wise softmax as follows.
+
+For :math:`j` from :math:`1` to :math:`T_c`, and :math:`i` from :math:`1` to :math:`T_r` calculate,
+
+.. math::
+   :nowrap:
+
+   \begin{align}
+      \tilde{m}_{ij}   &= \operatorname{rowmax}( X_{ij} ) \\
+      \tilde{P}_{ij}   &= \exp(X_{ij} - \tilde{m}_{ij} ) \\
+      \tilde{z}_{ij}   &= \operatorname{rowsum}( P_{ij} ) \\
+   \end{align}
+
+If :math:`j=1`, initialize running max, running sum, and the first column block of the output,
+
+.. math::
+   :nowrap:
+
+   \begin{align}
+      m_i            &= \tilde{m}_{i1} \\
+      z_i            &= \tilde{z}_{i1} \\
+      \tilde{Y}_{i1} &= \diag(\tilde{z}_{ij})^{-1} \tilde{P}_{i1}
+   \end{align}
+
+Else if :math:`j>1`,
+
+1. Update running max, running sum and column blocks :math:`k=1` to :math:`k=j-1`
+
+.. math::
+   :nowrap:
+
+   \begin{align}
+      m^{new}_i &= \max(m_i, \tilde{m}_{ij} ) \\
+      z^{new}_i &= \exp(m_i - m^{new}_i)\ z_i + \exp( \tilde{m}_{ij} - m^{new}_i )\ \tilde{z}_{ij}  \\
+      Y_{ik}    &= \diag(z^{new}_{i})^{-1} \diag(z_{i}) \exp(m_i - m^{new}_i)\ Y_{ik}
+   \end{align}
+
+2. Initialize column block :math:`j` of output and reset running max and running sum variables:
+
+.. math::
+   :nowrap:
+
+   \begin{align}
+      \tilde{Y}_{ij} &= \diag(z^{new}_{i})^{-1} \exp(\tilde{m}_{ij} - m^{new}_i ) \tilde{P}_{ij} \\
+      z_i            &= z^{new}_i \\
+      m_i            &= m^{new}_i \\
+   \end{align}

+===================
+CK docker hub
+===================
+
+`Docker hub <https://hub.docker.com/r/rocm/composable_kernel>`_
+
+-------------------------------------
+Why do I need this?
+-------------------------------------
+
+To make our lives easier and bring Composable Kernel dependencies together, we recommend using docker images.
+
+-------------------------------------
+So what is Composable Kernel?
+-------------------------------------
+
+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++.
+
+To get the CK library::
+
+    git clone https://github.com/ROCmSoftwarePlatform/composable_kernel.git
+
+
+
+run a docker container::
+
+    docker run                                                            \
+    -it                                                                   \
+    --privileged                                                          \
+    --group-add sudo                                                      \
+    -w /root/workspace                                                    \
+    -v ${PATH_TO_LOCAL_WORKSPACE}:/root/workspace                         \
+    rocm/composable_kernel:ck_ub20.04_rocm5.3_release                     \
+    /bin/bash
+
+and build the CK::
+
+    mkdir build && cd build
+    # Need to specify target ID, example below is for gfx908 and gfx90a
+    cmake                                                                                             \
+    -D CMAKE_PREFIX_PATH=/opt/rocm                                                                    \
+    -D CMAKE_CXX_COMPILER=/opt/rocm/bin/hipcc                                                         \
+    -D CMAKE_CXX_FLAGS="-O3"                                                                          \
+    -D CMAKE_BUILD_TYPE=Release                                                                       \
+    -D GPU_TARGETS="gfx908;gfx90a"                                                                    \
+    ..
+
+and::
+
+    make -j examples tests
+
+To run all the test cases including tests and examples run::
+
+    make test
+
+We can also run specific examples or tests like::
+
+    ./bin/example_gemm_xdl_fp16
+    ./bin/test_gemm_fp16
+
+For more details visit `CK github repo <https://github.com/ROCmSoftwarePlatform/composable_kernel>`_, `CK examples <https://github.com/ROCmSoftwarePlatform/composable_kernel/tree/develop/example)>`_, `even more CK examples <https://github.com/ROCmSoftwarePlatform/composable_kernel/tree/develop/client_example>`_.
+
+-------------------------------------
+And what is inside?
+-------------------------------------
+
+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/>`_
+* `Compiler <https://github.com/RadeonOpenCompute/llvm-project>`_
+
+-------------------------------------
+Which image is right for me?
+-------------------------------------
+
+Let's take a look at the image naming, for example "ck_ub20.04_rocm5.4_release". The image specs are:
+
+* "ck" - made for running Composable Kernel
+* "ub20.04" - based on Ubuntu 20.04
+* "rocm5.4" - ROCm platform version 5.4
+* "release" - compiler version is release
+
+So just pick the right image for your project dependencies and you're all set.
+
+-------------------------------------
+DIY starts here
+-------------------------------------
+
+If you need to customize a docker image or just can't stop tinkering, feel free to adjust the `Dockerfile <https://github.com/ROCmSoftwarePlatform/composable_kernel/blob/develop/Dockerfile>`_ for your needs.
+
+-------------------------------------
+License
+-------------------------------------
+
+CK is released under the MIT `license <https://github.com/ROCmSoftwarePlatform/composable_kernel/blob/develop/LICENSE>`_.

+CK Hello world
+===============
+
+-------------------------------------
+Motivation
+-------------------------------------
+
+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.
+
+During this tutorial we will have an introduction to the CK library, we will build it and run some examples and tests, so to say we will run a "Hello world" example. In future tutorials we will go in depth and breadth and get familiar with other tools and ways to integrate CK into your project.
+
+-------------------------------------
+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.
+
+So how do we (almost) reach the speed of light? CK acceleration abilities are based on:
+
+* Layered structure.
+* Tile-based computation model.
+* Tensor coordinate transformation.
+* Hardware acceleration use.
+* Support of low precision data types including fp16, bf16, int8 and int4.
+
+If you are excited and need more technical details and benchmarking results - read this awesome `blog post <https://community.amd.com/t5/instinct-accelerators/amd-composable-kernel-library-efficient-fused-kernels-for-ai/ba-p/553224>`_.

+-------------------------------------
+Hardware targets
+-------------------------------------
+
+CK library fully supports "gfx908" and "gfx90a" GPU architectures and only some operators are supported for "gfx1030". Let's check the hardware you have at hand and decide on the target GPU architecture
+
+==========     =========
+GPU Target     AMD GPU
+==========     =========
+gfx908 	       Radeon Instinct MI100
+gfx90a 	       Radeon Instinct MI210, MI250, MI250X
+gfx1030        Radeon PRO V620, W6800, W6800X, W6800X Duo, W6900X, RX 6800, RX 6800 XT, RX 6900 XT, RX 6900 XTX, RX 6950 XT
+==========     =========
+
+There are also `cloud options <https://aws.amazon.com/ec2/instance-types/g4/>`_ you can find if you don't have an AMD GPU at hand.
+
+-------------------------------------
+Build the library
+-------------------------------------
+
+First let's clone the library and rebase to the tested version::
+
+    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_rocm5.3_release" image, it is based on Ubuntu 20.04, ROCm v5.3, compiler release version.
+
+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_rocm5.3_release  \
+    /bin/bash
+
+If your current folder is different from ${HOME}, adjust the line `-v ${HOME}:/root/workspace` to fit your folder structure.
+
+Inside the docker container current folder is "~/workspace", library path is "~/workspace/composable_kernel", navigate to the library::
+
+    cd composable_kernel/
+
+Create and go to the "build" directory::
+
+    mkdir build && cd build
+
+In the previous section we talked about target GPU architecture. Once you decide which one is right for you, run cmake using the right GPU_TARGETS flag::
+
+    cmake  \
+    -D CMAKE_PREFIX_PATH=/opt/rocm  \
+    -D CMAKE_CXX_COMPILER=/opt/rocm/bin/hipcc  \
+    -D CMAKE_CXX_FLAGS="-O3"  \
+    -D CMAKE_BUILD_TYPE=Release  \
+    -D BUILD_DEV=OFF  \
+    -D GPU_TARGETS="gfx908;gfx90a;gfx1030" ..
+
+If everything went well the cmake run will end up with::
+
+    -- Configuring done
+    -- Generating done
+    -- Build files have been written to: "/root/workspace/composable_kernel/build"
+
+Finally, we can build examples and tests::
+
+    make -j examples tests
+
+If everything is smooth, you'll see::
+
+    Scanning dependencies of target tests
+    [100%] Built target tests
+
+---------------------------
+Run examples and tests
+---------------------------
+
+Examples are listed as test cases as well, so we can run all examples and tests with::
+
+    ctest
+
+You can check the list of all tests by running::
+
+    ctest -N
+
+We can also run them separately, here is a separate example execution::
+
+    ./bin/example_gemm_xdl_fp16 1 1 1
+
+The arguments "1 1 1" mean that we want to run this example in the mode: verify results with CPU, initialize matrices with integers and benchmark the kernel execution. You can play around with these parameters and see how output and execution results change.
+
+If everything goes well and you have a device based on gfx908 or gfx90a architecture you should see something like::
+
+    a_m_k: dim 2, lengths {3840, 4096}, strides {4096, 1}
+    b_k_n: dim 2, lengths {4096, 4096}, strides {1, 4096}
+    c_m_n: dim 2, lengths {3840, 4096}, strides {4096, 1}
+    launch_and_time_kernel: grid_dim {480, 1, 1}, block_dim {256, 1, 1}
+    Warm up 1 time
+    Start running 10 times...
+    Perf: 1.10017 ms, 117.117 TFlops, 87.6854 GB/s, DeviceGemmXdl<256, 256, 128, 4, 8, 32, 32, 4, 2> NumPrefetch: 1, LoopScheduler: Default, PipelineVersion: v1
+
+Meanwhile, running it on a gfx1030 device should result in::
+
+    a_m_k: dim 2, lengths {3840, 4096}, strides {4096, 1}
+    b_k_n: dim 2, lengths {4096, 4096}, strides {1, 4096}
+    c_m_n: dim 2, lengths {3840, 4096}, strides {4096, 1}
+    DeviceGemmXdl<256, 256, 128, 4, 8, 32, 32, 4, 2> NumPrefetch: 1, LoopScheduler: Default, PipelineVersion: v1 does not support this problem
+
+But don't panic, some of the operators are supported on gfx1030 architecture, so you can run a separate example like::
+
+    ./bin/example_gemm_dl_fp16 1 1 1
+
+and it should result in something nice similar to::
+
+    a_m_k: dim 2, lengths {3840, 4096}, strides {1, 4096}
+    b_k_n: dim 2, lengths {4096, 4096}, strides {4096, 1}
+    c_m_n: dim 2, lengths {3840, 4096}, strides {4096, 1}
+    arg.a_grid_desc_k0_m0_m1_k1_{2048, 3840, 2}
+    arg.b_grid_desc_k0_n0_n1_k1_{2048, 4096, 2}
+    arg.c_grid_desc_m_n_{ 3840, 4096}
+    launch_and_time_kernel: grid_dim {960, 1, 1}, block_dim {256, 1, 1}
+    Warm up 1 time
+    Start running 10 times...
+    Perf: 3.65695 ms, 35.234 TFlops, 26.3797 GB/s, DeviceGemmDl<256, 128, 128, 16, 2, 4, 4, 1>
+
+Or we can run a separate test::
+
+    ctest -R test_gemm_fp16
+
+If everything goes well you should see something like::
+
+    Start 121: test_gemm_fp16
+    1/1 Test #121: test_gemm_fp16 ...................   Passed   51.81 sec
+
+    100% tests passed, 0 tests failed out of 1

+Summary
+-----------
+
+In this tutorial we took the first look at the Composable Kernel library, built it on your system and ran some examples and tests. Stay tuned, in the next tutorial we will run kernels with different configs to find out the best one for your hardware and task.
+
+P.S.: Don't forget to switch out the cloud instance if you have launched one, you can find better ways to spend your money for sure!
