 On **Windows**, use `build_msvc.bat` in a Visual Studio Command Prompt to build with msvc, or you can use `make win64` to use mingw compiler toolchain from linux or windows to build the windows target. MSVC build will automatically use openmp and max threads appropriate for your CPU unless you set `OMP_NUM_THREADS` env.
 
+On **Centos 7**, **Amazon Linux 2018** use `rungnu` Makefile target: `make rungnu` or `make runompgnu` to use openmp.
