Installing and building for Microsoft Windows

Installing and building for Microsoft Windows#

This topic covers how to install hipBLAS on Microsoft Windows from a package and how to build and install it from the source code. For a list of installation prerequisites, see hipBLAS prerequisites.

Installing prebuilt packages#

hipBLAS can be installed on Windows 10 or 11 using the AMD HIP SDK installer.

The simplest way to use hipBLAS in your code is to use CMake. To install hipBLAS on Windows, follow these steps:

  1. Add the SDK installation location to CMAKE_PREFIX_PATH in the CMake configuration command:

    -DCMAKE_PREFIX_PATH="C:\hipSDK"

  2. Add the following lines to CMakeLists.txt:

    find_package(hipblas)
target_link_libraries( your_exe PRIVATE roc::hipblas )

Building and installing hipBLAS#

Most users do not need to build hipBLAS from source because it can be used after installing the prebuilt packages as described above. If necessary, users can follow these instructions to build hipBLAS from source.

Download the hipBLAS source code#

The hipBLAS source code is available from the hipBLAS folder of the rocm-libraries GitHub.The ROCm HIP SDK version might be shown in the default installation path, but you can run the HIP SDK compiler to display the version from the bin/ folder:

hipcc --version

The HIP version includes the major, minor, and patch fields, and possibly a build-specific identifier. As an example, the HIP version might be 5.4.22880-135e1ab4. This corresponds to major release = 5, minor release = 4, patch = 22880, and the build identifier 135e1ab4. The rocm-libraries GitHub contains branches with names like release/rocm-rel-major.minor. Select the branch where the major and minor fields correspond to the HIP version.

To download hipBLAS, including all projects in the rocm-libraries repository, use the following commands.

git clone -b release/rocm-rel-x.y https://github.com/ROCm/rocm-libraries.git
cd  rocm-libraries/projects/hipblas

Replace x.y in this command with the version of the HIP SDK installed on your machine. For example, if you have HIP 7.0 installed, then use -b release/rocm-rel-7.0. You can add the SDK tools to your path with an entry such as:

%HIP_PATH%\bin

To limit your local checkout to only the hipBLAS project, configure sparse-checkout before cloning. This uses the Git partial clone feature (--filter=blob:none) to reduce how much data is downloaded. Use the following commands for a sparse checkout:

Note

To include the hipBLAS dependencies, set the projects for the sparse checkout using git sparse-checkout set projects/hipblas projects/rocsolver projects/rocblas projects/hipblas-common.

git clone --no-checkout --filter=blob:none https://github.com/ROCm/rocm-libraries.git
cd rocm-libraries
git sparse-checkout init --cone
git sparse-checkout set projects/hipblas # add projects/rocsolver projects/rocblas, projects/hipblas-common to include dependencies
git checkout develop # or use the branch you want to work with

Note

To build ROCm 6.4.3 and older, use the hipBLAS repository at ROCm/hipBLAS. For more information, see the documentation associated with the release you want to build.

Building the library and library dependencies#

The root of the hipBLAS repository includes a helper Python script named rmake.py which lets you build and install hipBLAS with a single command. It accepts several options but has a hard-coded configuration that you can override by invoking cmake directly. However, it’s a great way to get started quickly and serves as an example of how to build and install hipBLAS. A few commands in the script require administrator access, so you might be prompted for a password.

Note

You can run the rmake.py script from the projects/hipblas directory.

Common examples showing how to use rmake.py to build the library dependencies and library are listed in this table:

Command

Description

python3 rmake.py -h

Help information.

python3 rmake.py -d

Build the library dependencies and library in your local directory. The -d flag only has to be used once. For subsequent invocations of rmake.py it’s not necessary to rebuild the dependencies.

python3 rmake.py

Build the library in your local directory. It is assumed the dependencies have been built.

python3 rmake.py -i

Build the library, then build and install the hipBLAS package in C:\\hipSDK. You will be prompted for admin access. This installs it for all users. To restrict hipBLAS to your local directory, do not use the -i flag.

python3 rmake.py -n

Build the library without the functionality provided by rocSOLVER. The rocSOLVER, rocSPARSE, and rocPRIM dependencies will not be required. This flag has no effect when building with a NVIDIA CUDA backend.

Building the library, client, and library and client dependencies#

The client contains the executables listed in the table below.

Executable name

Description

hipblas-test

Runs Google Tests to test the library

hipblas-bench

An executable to benchmark or test individual functions

hipblas-example-*

Various examples showing how to use hipBLAS

Common ways to use rmake.py to build the dependencies, library, and client are listed in this table.

Command

Description

python3 rmake.py -dc

Build the library dependencies, client dependencies, library, and client in your local directory. The -d flag only has to be used once. For subsequent invocations of rmake.py, it is not necessary to rebuild the dependencies.

python3 rmake.py -c

Build the library and client in your local directory. It is assumed the dependencies have been built.

python3 rmake.py -idc

Build the library dependencies, client dependencies, library, and client, then build and install the hipBLAS package. You will be prompted for administrator access. To install hipBLAS for all users, use the -i flag. To restrict hipBLAS to your local directory, do not use the -i flag.

python3 rmake.py -ic

Build and install the hipBLAS package and build the client. You will be prompted for administrator access. This installs it for all users. To restrict hipBLAS to your local directory, do not use the -i flag.

Dependencies for building the library#

Use rmake.py with the -d option to install the dependencies required to build the library. This does not install the hipblas-common, rocBLAS, rocSOLVER, rocSPARSE, and rocPRIM dependencies. When building hipBLAS, it is important to take note of the version dependencies for other libraries. The hipblas-common, rocBLAS, and rocSOLVER versions required to build for an AMD backend are listed in the top-level CMakeLists.txt file. rocSPARSE and rocPRIM are currently dependencies of rocSOLVER. To build these libraries from source, see the rocBLAS, rocSOLVER, rocSPARSE, and rocPRIM documentation..

The minimum version of CMake is currently 3.16.8. See the --cmake_install flag in rmake.py to upgrade automatically.

To use the test and benchmark clients’ host reference functions, you must manually download and install AMD’s ILP64 version of the AOCL libraries version 4.2. If you download and run the full Windows AOCL installer to the default location (C:\Program Files\AMD\AOCL-Windows\), then the AOCL reference BLAS (amd-blis) should be found by the clients’ CMakeLists.txt file.

Note

If you only use the rmake.py -d dependency script and change the default CMake option LINK_BLIS=ON, you might experience hipblas-test stress test failures due to a 32-bit integer overflow on the host. To resolve this issue, exclude the stress tests using the command line argument --gtest_filter=-*stress*.
