**************************
Install Composable Kernel
**************************
Before you begin, verify that your system is supported. For more information, see :ref:`ROCm Core SDK components <rocm:release-components>`.
For advanced workflows, source builds, or custom configurations, see :doc:`./Composable-Kernel-build`.
.. _install-rocm:
Install the ROCm Core SDK
=========================
Composable Kernel (CK) is included with the ROCm Core SDK on Linux and Windows. For the complete Core SDK installation, use the
``amdrocm-core-sdk`` package. See :doc:`Install AMD ROCm <rocm:install/rocm>` for more information.
.. _install-base:
Install the Composable Kernel package on Linux
================================================
Alternatively, you can use the ``amdrocm-ck`` package to install Composable Kernel without the full ROCm Core SDK.
1. Complete the :doc:`ROCm installation prerequisites <rocm:install/rocm>` to
install dependencies and configure GPU access permissions.
2. Install the Composable Kernel package that matches your desired ROCm version. Package
names use the following format:
.. code-block:: shell-session
amdrocm-ck<rocm_version>-<llvm_target>
Where:
* ``<rocm_version>`` is the ROCm Core SDK version to install. Omit this
suffix to install the latest available version.
* ``<llvm_target>`` (starting with ``gfx``) is used if you are installing
for a single AMD GPU architecture. Omit this suffix to install for all
architectures at the cost of disk space.
For example, to install the latest Composable Kernel development package release for
supported GPU architectures:
.. tab-set::
.. tab-item:: Debian-based distros
.. code-block:: bash
sudo apt install amdrocm-ck<rocm_version>-<llvm_target>
.. tab-item:: RHEL-based distros
.. code-block:: bash
sudo dnf install amdrocm-ck<rocm_version>-<llvm_target>
.. tab-item:: SLES
.. code-block:: bash
sudo zypper install amdrocm-ck<rocm_version>-<llvm_target>
.. _install-nightly:
Install a nightly build
=======================
The `TheRock <https://github.com/ROCm/TheRock>`__ build system also publishes nightly builds for the ROCm Core SDK and its components, including Composable Kernel. See `Nightly release status <https://github.com/ROCm/TheRock#nightly-release-status>`__ for details.
.. note::
If you choose to install from a nightly build artifact, you'll need to set ``HIP_PLATFORM=amd`` and ``LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/rocm/lib`` after installation.
