Environment
We’ll work with whatever machines you have available for development (remote
access is fine). Preferably, you have the AVX2 ISA extension available
(lscpu|grep avx2). Even better, you have have AVX-512 available for testing.
You will need git, cmake, and GCC. At least GCC 11, preferably version 13 or 14.
Local setup
Setup your environment with the paths you like. I’ll use the following variables:
src=~/src
prefix=~/local
export CMAKE_PREFIX_PATH=$prefix
Optional: install latest GCC from source
If you want to build it quicker add --disable-bootstrap to the GCC
configure flags.
cd $src
git clone --depth 1 --single-branch --branch releases/gcc-14 \
git://gcc.gnu.org/git/gcc
cd gcc
./contrib/download_prerequisites
mkdir build
cd build
../configure --prefix=$prefix/gcc14 --enable-languages=c++ --disable-multilib
make -j8
make install
export CC=$prefix/gcc14/bin/gcc
export CXX=$prefix/gcc14/bin/g++
Install Google Benchmark (master branch)
cd $src
git clone --depth 1 https://github.com/google/benchmark.git
cd benchmark
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=$prefix -DBENCHMARK_ENABLE_TESTING=OFF \
-DCMAKE_BUILD_TYPE=Release ..
make -j24
make install
Install vir-simd
cd $src
git clone https://github.com/mattkretz/vir-simd.git
cd vir-simd
make install prefix=$prefix
Prepare Benchmark Exercises
cd $src
git clone https://git.gsi.de/mkretz/simd-benchmark-exercises simd-benchmarks
cd simd-benchmarks
make -j8
