Build and Install

Requirements:

• NVIDIA GPU with CUDA 11
• cmake 3.18 onward
• C++14 enabled compiler, GCC 9

More details about build tools

• The table gives a quick view of toolchain compatibility

• more reference: 1) CUDA compilers, 2) CUDA architectures & gencode.

CUDA	11.0	11.1	11.2	11.3	11.4	11.5	11.6	11.7	11.8
gcc	7	7	7	7	7	7	7
		8	8	8	8	8	8	8	8
					9	9	9	9	9

git clone https://github.com/szcompressor/cuSZ.git cusz-latest
cd cusz-latest && mkdir build && cd build

# Example architectures (";"-separated when specifying)
#   Volta        : 70
#   Turing       : 75
#   Ampere       : 80 86
#   Ada Lovelace : 89 (as of CUDA 11.8)
#   Hopper       : 90 (as of CUDA 11.8)
cmake .. -DCUSZ_BUILD_EXAMPLES=on \
    -DCMAKE_BUILD_TYPE=Release \
    -DCUSZ_BUILD_TESTS=on \
    -DCMAKE_INSTALL_PREFIX=[/path/to/install/dir] \
    -DCMAKE_CUDA_ARCHITECTURES="75;80;86"
make -j8
# Install to [/path/to/install/dir]
make install
# An optional testcase run can be done using `ctest`.

For CUDA 11.4 or older, given the different machanism of finding NVIDIA::CUB, use need to otherwise specify CUB_DIR, which is basically $CUDA_HOME/include/cub/cmake. A one-liner is given below,

cmake .. -DCUSZ_BUILD_EXAMPLES=on \
    -DCMAKE_BUILD_TYPE=Release \
    -DCUSZ_BUILD_TESTS=on \
    -DCMAKE_INSTALL_PREFIX=[/path/to/install/dir] \
    -DCUB_DIR=$(dirname $(which nvcc))/../include/cub/cmake \
    -DCMAKE_CUDA_ARCHITECTURES="75;80;86"
# ... and follow the same subsequent commands
