Building AMD GPU BLAS Library (rocBLAS) from Source

1. Prerequisites

Install ROCm

2. Download Sources

$ git clone --recursive git@github.com:ROCm/rocBLAS.git
# Alternative: git clone --recursive https://github.com/ROCm/rocBLAS.git
cd rocBLAS
git checkout rocm-6.0.2

rocBLAS clone

3. Build Debug Version

$ conda deactivate
$ conda deactivate
$ conda deactivate

Enable CMake variables to show build command details:

export CXX=/opt/rocm/bin/hipcc \
&& cmake -DCMAKE_INSTALL_PREFIX=../../../local_d_noT_906_908_1030/rocblas/ \
-DCMAKE_BUILD_TYPE=Debug \
-DCMAKE_RULE_MESSAGES:BOOL=OFF \
-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \
-DCMAKE_Fortran_COMPILER="gfortran" \
-DBUILD_CLIENTS_TESTS:BOOL=ON \
-DBUILD_CLIENTS_BENCHMARKS:BOOL=ON \
-DBUILD_CLIENTS_SAMPLES:BOOL=ON \
-DBUILD_WITH_TENSILE=OFF \
../../

$ make -j

Build result:

Debug build output

Simplified version (only verbose output):

export CXX=/opt/rocm/bin/hipcc \
&& cmake -DCMAKE_INSTALL_PREFIX=../../../local_d_cmake/rocblas/ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_VERBOSE_MAKEFILE=ON ../../

Sample compilation command for a single .cpp file:

Modify CMakeLists.txt to Build Only for gfx906 and gfx941 Architectures

export CXX=/opt/rocm/bin/hipcc \
&& cmake -DCMAKE_INSTALL_PREFIX=../../../local_d_notensile_906_941/rocblas/ \
-DCMAKE_BUILD_TYPE=Debug \
-DCMAKE_RULE_MESSAGES:BOOL=OFF \
-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \
../../

4. Build Release Version

export CXX=/opt/rocm/bin/hipcc \
&& cmake -DCMAKE_INSTALL_PREFIX=../../../local_d_cmake/rocblas/ -DCMAKE_BUILD_TYPE=Release -DCMAKE_VERBOSE_MAKEFILE=ON ../../
