Installation on Linux

Installation on Linux#

Install pre-built packages#

Download pre-built packages from ROCm’s package servers. Updates to each release are listed in the CHANGELOG.md file under the releases tab of the hipSOLVER GitHub page.

  • sudo apt update && sudo apt install hipsolver

Note

The pre-built packages depend on the third-party library SuiteSparse, which must be installed on the system prior to installing hipSOLVER. SuiteSparse can be installed using the package manager of most distros.

Build & install library using script (Ubuntu only)#

The root of the hipSOLVER repository has a helper bash script install.sh to build and install hipSOLVER on Ubuntu with a single command. It does not take a lot of options and hard-codes configuration that can be specified through invoking cmake directly, but it’s a great way to get started quickly and can serve as an example of how to build/install. A few commands in the script need sudo access, so it may prompt you for a password.

  • ./install.sh -id — build library, build dependencies, and install (-d flag only needs to be passed once on a system).

  • ./install.sh -ic — build library, build clients (tests, benchmarks, and samples), and install.

  • ./install.sh --cuda — build library on a CUDA-enabled machine, with cuSOLVER as the backend.

  • ./install.sh --no-sparse — build library without hipsolverSp functionality, with rocSOLVER as the backend.

To see more options, use the help option of the install script.

  • ./install.sh -h

Build & install library manually#

For a standard library installation, follow these steps:

mkdir -p <HIPSOLVER_BUILD_DIR_PATH>/release
cd <HIPSOLVER_BUILD_DIR_PATH>/release
CXX=/opt/rocm/bin/hipcc cmake <HIPSOLVER_SOURCE_DIR_PATH>
make -j$(nproc)
sudo make install

sudo is required if installing into a system directory such as /opt/rocm, which is the default option.

  • Use -DCMAKE_INSTALL_PREFIX=<other_path> to specify a different install directory.

  • Use -DCMAKE_BUILD_TYPE=<other_configuration> to specify a build configuration, such as ‘Debug’. The default build configuration is ‘Release’.

Library dependencies#

The hipSOLVER library has two separate sets of dependencies, depending on the desired backend. The cuSOLVER backend has the following dependencies:

  1. cuSOLVER

The rocSOLVER backend has the following dependencies:

  1. rocSOLVER

  2. rocBLAS

  3. rocSPARSE (optional, required by default)

  4. SuiteSparse modules CHOLMOD and SuiteSparse_config (optional, required by default)

rocSOLVER itself depends on rocBLAS and rocSPARSE, therefore all three libraries should be present with a standard rocSOLVER installation. For more information about building and installing rocSOLVER, refer to the rocSOLVER documentation.

SuiteSparse is a third-party library, and can be installed using the package managers of most distros. Together with rocSPARSE, it is used to provide functionality for the hipsolverSp API. If only hipsolverDn and/or hipsolverRf are needed, these dependencies can be ignored by setting the BUILD_WITH_SPARSE option to OFF.

  • DBUILD_WITH_SPARSE=OFF

Build library + tests + benchmarks + samples manually#

The repository contains source code for client programs that serve as tests, benchmarks, and samples. Client source code can be found in the clients subdirectory.

Client dependencies#

The hipSOLVER samples have no external dependencies, but our unit test and benchmarking applications do. These clients introduce the following dependencies:

  1. lapack (lapack itself brings a dependency on a fortran compiler)

  2. googletest

  3. hipBLAS (optional)

  4. hipSPARSE (optional, required by default)

Unfortunately, many distros do not provide a googletest package with pre-compiled libraries, and the lapack packages do not have the necessary cmake config files for cmake to configure linking the cblas library. hipSOLVER provides a cmake script that builds lapack and googletest from source. This is an optional step; users can provide their own builds of these dependencies and help cmake find them by setting the CMAKE_PREFIX_PATH definition. The following is a sequence of steps to build dependencies and install them to the cmake default, /usr/local:

mkdir -p <HIPSOLVER_BUILD_DIR_PATH>/release/deps
cd <HIPSOLVER_BUILD_DIR_PATH>/release/deps
cmake -DBUILD_BOOST=OFF <HIPSOLVER_SOURCE_PATH>/deps   #assuming boost is installed through package manager as above
make -j$(nproc) install

hipBLAS is only required if the BUILD_HIPBLAS_TESTS option is set to ON, and is used to ensure compatibility between the hipblas enums defined separately by hipBLAS and hipSOLVER. hipSPARSE is required by default but can be ignored if the BUILD_WITH_SPARSE option is set to OFF, and is used to create objects required by tests for the hipsolverSp API.

  • DBUILD_HIPBLAS_TESTS=ON

  • DBUILD_WITH_SPARSE=OFF

Both libraries can be installed similarly to hipSOLVER. For example, the install scripts for hipBLAS and hipSPARSE can each be invoked to build and install the respective library via:

  • ./install.sh -i

Find more details in the hipBLAS documentation and the hipSPARSE documentation.

Library and clients#

Once dependencies are available on the system, it is possible to configure the clients to build. This requires a few extra cmake flags to the library’s cmake configure script. If the dependencies are not installed into system defaults (like /usr/local), you should pass the CMAKE_PREFIX_PATH to cmake to help find them.

  • -DCMAKE_PREFIX_PATH="<semicolon separated paths>"

CXX=/opt/rocm/bin/hipcc cmake -DBUILD_CLIENTS_TESTS=ON -DBUILD_CLIENTS_BENCHMARKS=ON [HIPSOLVER_SOURCE]
make -j$(nproc)
sudo make install   # sudo required if installing into system directory such as /opt/rocm
