Could you please suggest a mechanism that tests support for unified virtual memory in CUDA? According to https://developer.nvidia.com/blog/beyond-gpu-memory-limits-unified-memory-pascal/, the underlaying page migration mechanism is supported since Pascal, making me wonder why clang insists on a Volta-generation GPU for `#pragma omp requires unified_shared_memory`.
