Experimental issue : OpenMP on macOS, homebrew llvm + libomp #13

Open rageworx opened 1 year ago

rageworx commented 1 year ago

Default llvm (clang) of macOS not supports openmp basically. Experimental performance enhancement for Intel CPU based Mac systems.

rageworx commented 1 year ago

homebrew llvm should be installed by brew install llvm.

rageworx commented 1 year ago

homebrew openmp should be installed by brew install libomp.

rageworx commented 1 year ago

Some makefiles created for testing openmp.

rageworx commented 1 year ago

Generating dylib successfully done, with makefiles/Makefile.homebrewllvm with make dylib. homebrew llvm doesn't support multi-architecture, Cannot use multiple -arch parameters for universal binary.

rageworx commented 1 year ago

homebrew llvm dylib + macOS native llvm-gcc linking successfully worked.
