The Clang/LLVM tends to behave similarly, but can be guided to properly vectorize the inner loop with either flags `-O3 -ffast-math -march=native -fno-unroll-loops -mllvm -force-vector-width=8` or pragmas such as `#pragma clang loop vectorize_width(8)` and `#pragma clang loop unroll(disable)`.

!!! note
It may be advantageous to use NVPL libraries instead NVHPC ones. For example DGEMM BLAS 3 routine from NVPL is almost 30% faster than NVHPC one.

Similarly Clang for Grace toolchain with NVPL BLAS can be used to compile C++ version of the example.
