AMD ROCm Software

ROCm is an open-source stack, composed primarily of open-source software, designed for graphics processing unit (GPU) computation. ROCm consists of a collection of drivers, development tools, and APIs that enable GPU programming from low-level kernel to end-user applications.

With ROCm, you can customize your GPU software to meet your specific needs. You can develop, collaborate, test, and deploy your applications in a free, open source, integrated, and secure software ecosystem. ROCm is particularly well-suited to GPU-accelerated high-performance computing (HPC), artificial intelligence (AI), scientific computing, and computer aided design (CAD).

ROCm is powered by AMD’s Heterogeneous-computing Interface for Portability (HIP), an open-source software C++ GPU programming environment and its corresponding runtime. HIP allows ROCm developers to create portable applications on different platforms by deploying code on a range of platforms, from dedicated gaming GPUs to exascale HPC clusters.

ROCm supports programming models, such as OpenMP and OpenCL, and includes all necessary open source software compilers, debuggers, and libraries. ROCm is fully integrated into machine learning (ML) frameworks, such as PyTorch and TensorFlow.

Getting the ROCm Source Code

AMD ROCm is built from open source software. It is, therefore, possible to modify the various components of ROCm by downloading the source code and rebuilding the components. The source code for ROCm components can be cloned from each of the GitHub repositories using git. For easy access to download the correct versions of each of these tools, the ROCm repository contains submodules that point to the correct versions of each of the ROCm components. They can be found in the /libs directory of the ROCm repository.

Installing git-lfs

Some ROCm projects use the Git Large File Storage (LFS) format that may require you to install git-lfs. Refer to Git Large File Storage for more information. For example, to install git-lfs for Ubuntu, use the following command:

sudo apt-get install git-lfs

Downloading the ROCm source code

The following example shows how to download the ROCm source from this repository.

git clone https://github.com/ROCm/ROCm -b submodules-6-3-0 --recurse-submodules

Building the ROCm source code

Each ROCm component repository contains directions for building that component, such as the rocSPARSE documentation Installation and Building for Linux. Refer to the specific component documentation for instructions on building the repository.

Each release of the ROCm software supports specific hardware and software configurations. Refer to System requirements (Linux) for the current supported hardware and OS.

Build ROCm from source

The Build will use as many processors as it can find to build in parallel. Some of the compiles can consume as much as 10GB of RAM, so make sure you have plenty of Swap Space !

By default the ROCm build will compile for all supported GPU architectures and will take approximately 500 CPU hours. The Build time will reduce significantly if we limit the GPU Architecture/s against which we need to build by using the environment variable GPU_ARCHS as mentioned below.

# --------------------------------------
# Step1: clone source code
# --------------------------------------

mkdir -p ~/WORKSPACE/      # Or any folder name other than WORKSPACE
cd ~/WORKSPACE/
export ROCM_VERSION=6.3.0   # or 6.2.0 6.1.0
git clone https://github.com/ROCm/ROCm -b submodules-${ROCM_VERSION} --recurse-submodules

# --------------------------------------
# Step 2: Prepare build environment
# --------------------------------------

# Option 1: Start a docker container
# Pulling required base docker images:
# Ubuntu20.04 built from ROCm/tools/rocm-build/docker/ubuntu20/Dockerfile
docker pull rocm/rocm-build-ubuntu-20.04:6.2
# Ubuntu22.04 built from ROCm/tools/rocm-build/docker/ubuntu22/Dockerfile
docker pull rocm/rocm-build-ubuntu-22.04:6.2
# Ubuntu24.04 built from ROCm/tools/rocm-build/docker/ubuntu24/Dockerfile
docker pull rocm/rocm-build-ubuntu-24.04:6.2

# Start docker container and mount the source code folder:
docker run -ti \
    -e ROCM_VERSION=${ROCM_VERSION} \
    -e CCACHE_DIR=$HOME/.ccache \
    -e CCACHE_ENABLED=true \
    -e DOCK_WORK_FOLD=/src \
    -w /src \
    -v $PWD:/src \
    -v /etc/passwd:/etc/passwd \
    -v /etc/shadow:/etc/shadow \
    -v ${HOME}/.ccache:${HOME}/.ccache \
    -u $(id -u):$(id -g) \
    <replace_with_required_ubuntu_base_docker_image> bash

# Option 2: Install required packages into the host machine
# For ubuntu20.04 system
cd ROCm/tools/rocm-build/docker/ubuntu20
cp * /tmp && cd /tmp
bash install-prerequisites.sh
# For ubuntu22.04 system
cd ROCm/tools/rocm-build/docker/ubuntu22
cp * /tmp && cd /tmp
bash install-prerequisities.sh
# For ubuntu24.04 system
cd ROCm/tools/rocm-build/docker/ubuntu24
cp * /tmp && cd /tmp
bash install-prerequisites.sh

# --------------------------------------
# Step 3: Run build command line
# --------------------------------------

# Select GPU targets before building:
# When GPU_ARCHS is not set, default GPU targets supported by ROCm6.1 will be used.
# To build against a subset of GFX architectures you can use the below env variable.
# Support MI300 (gfx940, gfx941, gfx942).
export GPU_ARCHS="gfx942"               # Example
export GPU_ARCHS="gfx940;gfx941;gfx942" # Example

# Pick and run build commands in the docker container:
# Build rocm-dev packages
make -f ROCm/tools/rocm-build/ROCm.mk -j ${NPROC:-$(nproc)} rocm-dev
# Build all ROCm packages
make -f ROCm/tools/rocm-build/ROCm.mk -j ${NPROC:-$(nproc)} all
# list all ROCm components to find required components
make -f ROCm/tools/rocm-build/ROCm.mk list_components
# Build a single ROCm packages
make -f ROCm/tools/rocm-build/ROCm.mk T_rocblas
