[Openmp-dev] Building and Using LLVM/Clang 7.0 with OpenMP Offloading to NVIDIA GPUs

[Itaru Kitayama via Openmp-dev]

Jonas,
Could you tell me how the module file is written, removing
system-specific information, but
leaving relevant for the CUDA Toolkit installation? The path to binary
needs to be in PATH,
and libraries in LD_LIBRARY_PATH I suppose, but not sure if there
needs to be other than that.
