Install Composable Kernel

Install Composable Kernel#

Before you begin, verify that your system is supported. For more information, see ROCm Core SDK components.

For advanced workflows, source builds, or custom configurations, see Build and install Composable Kernel from source.

Install the ROCm Core SDK#

Composable Kernel (CK) is included with the ROCm Core SDK on Linux and Windows. For the most complete installation, we recommend that developers use the amdrocm-core-sdk meta package on Linux.

For instructions, see Install AMD ROCm. Use the selector panel on that page to view instructions appropriate for your system environment.

Install the ROCm CK package on Linux#

Alternatively, if you want to install Composable Kernel as part of the ROCm without additional ROCm libraries and tools, install the amdrocm-ck package.

  1. Complete the ROCm installation prerequisites to install dependencies and configure GPU access permissions.

  2. Install the ROCm CK package that matches your desired ROCm version. Package names use the following format:

    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:

    sudo apt install amdrocm-ck

    sudo dnf install amdrocm-ck

    sudo zypper install amdrocm-ck

Install a nightly build#

The TheRock build system also publishes nightly builds for the ROCm Core SDK and its components, including Composable Kernel. See Nightly release status for details.
