Building and Installing#
Installing from AMD ROCm repository#
rocALUTION can be installed from AMD ROCm repository. The repository hosts the single-node, accelerator enabled version of the library. If a different setup is required, e.g. multi-node support, rocALUTION need to be built from source, see Building from GitHub repository.
For detailed instructions on how to set up ROCm on different platforms, see the AMD ROCm Platform Installation Guide for Linux.
rocALUTION has the following run-time dependencies
Building from GitHub repository#
To build rocALUTION from source, the following compile-time and run-time dependencies must be met
CMake 3.5 or later
AMD ROCm 2.9 or later (optional, for HIP support)
rocSPARSE (optional, for HIP support)
rocBLAS (optional, for HIP support)
rocPRIM (optional, for HIP support)
OpenMP (optional, for OpenMP support)
MPI (optional, for multi-node / multi-GPU support)
googletest (optional, for clients)
Download rocALUTION#
The rocALUTION source code is available at the rocALUTION GitHub page. Download the master branch using:
$ git clone -b master https://github.com/ROCmSoftwarePlatform/rocALUTION.git
$ cd rocALUTION
Below are steps to build different packages of the library, including dependencies and clients. It is recommended to install rocALUTION using the install.sh script.
Using install.sh script to build rocALUTION with dependencies#
The following table lists common uses of install.sh to build dependencies + library. Accelerator support via HIP and OpenMP will be enabled by default, whereas MPI is disabled.
./install.sh -h Print help information. ./install.sh -d Build dependencies and library in your local directory. The -d flag only needs to be used once. For subsequent invocations of install.sh it is not necessary to rebuild the dependencies. ./install.sh Build library in your local directory. It is assumed dependencies are available. ./install.sh -i Build library, then build and install rocALUTION package in /opt/rocm/rocalution. You will be prompted for sudo access. This will install for all users. ./install.sh –host Build library in your local directory without HIP support. It is assumed dependencies are available. ./install.sh –mpi=<dir> Build library in your local directory with HIP and MPI support. It is assumed dependencies are available. ========================== ====
Using install.sh script to build rocALUTION with dependencies and clients#
The client contains example code, unit tests and benchmarks. Common uses of install.sh to build them are listed in the table below.
Command |
Description |
---|---|
./install.sh -h |
Print help information. |
./install.sh -dc |
Build dependencies, library and client in your local directory. The -d flag only needs to be used once. For subsequent invocations of install.sh it is not necessary to rebuild the dependencies. |
./install.sh -c |
Build library and client in your local directory. It is assumed dependencies are available. |
./install.sh -idc |
Build library, dependencies and client, then build and install rocALUTION package in /opt/rocm/rocalution. You will be prompted for sudo access. This will install for all users. |
./install.sh -ic |
Build library and client, then build and install rocALUTION package in opt/rocm/rocalution. You will be prompted for sudo access. This will install for all users. |
Using individual commands to build rocALUTION#
CMake 3.5 or later is required in order to build rocALUTION without the use of install.sh.
rocALUTION can be built with cmake using the following commands:
# Create and change to build directory
mkdir -p build/release ; cd build/release
# Default install path is /opt/rocm, use -DCMAKE_INSTALL_PREFIX=<path>
# to adjust it. In this case, rocALUTION is built with HIP and
# OpenMP support.
# MPI support is disabled.
cmake ../.. -DSUPPORT_HIP=ON \
-DSUPPORT_MPI=OFF \
-DSUPPORT_OMP=ON
# Compile rocALUTION library
make -j$(nproc)
# Install rocALUTION to /opt/rocm
sudo make install
GoogleTest is required in order to build all rocALUTION clients.
rocALUTION with dependencies and clients can be built using the following commands:
# Install googletest
mkdir -p build/release/deps ; cd build/release/deps
cmake ../../../deps
sudo make -j$(nproc) install
# Change to build directory
cd ..
# Default install path is /opt/rocm, use -DCMAKE_INSTALL_PREFIX=<path>
# to adjust it. By default, HIP and OpenMP support are enabled,
# MPI support is disabled.
cmake ../.. -DBUILD_CLIENTS_TESTS=ON \
-DBUILD_CLIENTS_SAMPLES=ON
# Compile rocALUTION library
make -j$(nproc)
# Install rocALUTION to /opt/rocm
sudo make install
The compilation process produces a shared library file librocalution.so and librocalution_hip.so if HIP support is enabled. Ensure that the library objects can be found in your library path. If you do not copy the library to a specific location you can add the path under Linux in the LD_LIBRARY_PATH variable.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path_to_rocalution>
Common build problems#
- Issue: Could not find a package file provided by “ROCM” with any of the following names:
ROCMConfig.cmake rocm-config.cmake
Solution: Install ROCm cmake modules either from source or from AMD ROCm repository.
- Issue: Could not find a package file provided by “ROCSPARSE” with any of the following names:
ROCSPARSE.cmake rocsparse-config.cmake
Solution: Install rocSPARSE either from source or from AMD ROCm repository.
- Issue: Could not find a package file provided by “ROCBLAS” with any of the following names:
ROCBLAS.cmake rocblas-config.cmake
Solution: Install rocBLAS either from source or from AMD ROCm repository.
Simple Test#
You can test the installation by running a CG solver on a sparse matrix. After successfully compiling the library, the CG solver example can be executed.
cd rocALUTION/build/release/clients/staging
wget ftp://math.nist.gov/pub/MatrixMarket2/Harwell-Boeing/laplace/gr_30_30.mtx.gz
gzip -d gr_30_30.mtx.gz
./cg gr_30_30.mtx
