Installation#

Install pre-built packages#

Download pre-built packages from ROCm’s package servers. Release notes are available on the releases tab of the library’s github page.

  • sudo apt update && sudo apt install hipsolver

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.

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’.

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.

Dependencies (only necessary for hipSOLVER clients)#

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

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 provide a cmake script that builds the above dependencies 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

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
