Getting started

To clone the repo, compile the code and run the benchmarks:

git clone --recursive https://github.com/ssciwr/high-performance-cpp.git
cd high-performance-cpp
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .
./bench/bench

Notes

• CMake 3.16 gave a target "BLAS::BLAS" error on Ubuntu (see #13)
  • Using a more recent CMake version is one solution to this problem
• Apple clang on M1 mac doesn't support the -march=native flag
  • Possible alternatives: -mcpu=apple-m1 or -mcpu=apple-a14
  • -march=native will be supported by on M1 by clang 15
