Are You Ready to ROCK!
The ROCm Platform delivers on the vision of the Boltzmann Initiative, bringing new opportunities in GPU Computing Research.
On November 16th, 2015, the Radeon Technology Group rolled out Boltzmann Initiative with three core foundation elements:
- New Linux(R) Driver and Runtime Stack optimized for HPC & Ultra-scale class computing,
- Heterogeneous C and C++ compiler which best address the whole system not just a single device
- HIP acknowledging the need for platform choice when utilizing GPU computing API
Using our knowledge of the HSA Standards and, more importantly, the HSA 1.0 Runtime we have been able to successfully extended support to the dGPU with critical features for NUMA class acceleration. As a result, the ROCK driver is composed of several components based on our efforts to develop the Heterogeneous System Architecture for APUs, including the new AMDGPU driver, the Kernel Fusion Driver (KFD), the HSA+ Runtime and an LLVM based compilation stack for the building of key language support. This support starts with AMD’s FIJI Family of dGPU, but support is planned to expand in the future to include future ASICS.
The Latest ROCm Platform - ROCm 1.0
The latest tested version of the drivers, tools, libraries and source code for the ROCm platform have been released and are available under the roc-1.0 branch of the following GitHub repositories:
- ROCK-Kernel-Driver
- ROCR-Runtime
- ROCT-Thunk-Interface
- HCC compiler
- LLVM-AMDGPU-Assembler-Extra
- ROCnRDMA
In addition the following mirror repositories that support the HCC compiler are also available on GitHub, and frozen for the roc-1.0 release:
Installing from AMD ROCm Repositories
AMD is hosting both debian and rpm repositories for the ROCm 1.0 packages. The packages in both repositories have been signed to ensure package integrity. Directions for each repository are given below:
Debian repository - apt-get
For Debian based systems, like Ubuntu, configure the Debian ROCm repository as follows:
wget -qO - http://atlpackages01.amd.com:81/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
sudo sh -c 'echo deb [arch=amd64] http://atlpackages01.amd.com:81/rocm/apt/debian/ trusty main > /etc/apt/sources.list.d/rocm.list'
Finally, update the apt-get repository list and install the rocm-rel driver package and the rocm-dev development package:
sudo apt-get update
sudo apt-get install rocm-rel
sudo apt-get install rocm-dev
To un-install the entire rocm-dev development package execute:
sudo apt-get autoremove rocm-dev
The rocm driver package can be un-installed in a similar way, but the kernel images will remain on the system because apt-get will never remove old kernels by default (refer to the file /etc/apt/apt.conf.d/01autoremove-kernels). Kernel images can be removed manually using dpkg or apt-get directly on the package names.
RPM repository - dnf (yum)
Closed Source Components
The ROCm platform relies on a few closed source components to provide legacy functionality like HSAIL finalization and debugging/profiling support. These components are only available through the ROCm repositories, and will either be deprecated or become open source components in the future. These components are made available in the following packages:
- hsa-ext-rocm-dev
Getting ROCm Source Code
Modifications can be made to the ROCm 1.0 components by modifying the open source code base and rebuilding the components. Source code can be cloned from each of the GitHub repositories using git, or users can use the repo command and the ROCm 1.0 manifest file to download the entire ROCm 1.0 source code.
Installing repo
Google's repo tool allows you to manage multiple git repositories simultaneously. You can install it by executing the following commands:
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Note: make sure ~/bin exists and it is part of your PATH
Cloning the code
mkdir ROCm && cd ROCm
repo init -u https://github.com/RadeonOpenCompute/ROCm.git -b roc-1.0
repo sync
These series of commands will pull all of the open source code associated with the ROCm 1.0 release.
