	Evaluates to true on success. More...
#define	CUDA_FAILED(x)   (CUDA(x) != cudaSuccess)
	Evaluates to true on failure. More...
#define	CUDA_VERIFY(x)   if(CUDA_FAILED(x)) return false;
	Return from the boolean function if CUDA call fails. More...
#define	LOG_CUDA   "[cuda] "
	LOG_CUDA string. More...
#define	CUDA_FREE(x)   if(x != NULL) { cudaFree(x); x = NULL; }
	Check for non-NULL pointer before freeing it, and then set the pointer to NULL. More...
#define	CUDA_FREE_HOST(x)   if(x != NULL) { cudaFreeHost(x); x = NULL; }
	Check for non-NULL pointer before freeing it, and then set the pointer to NULL. More...
#define	SAFE_DELETE(x)   if(x != NULL) { delete x; x = NULL; }
	Check for non-NULL pointer before deleting it, and then set the pointer to NULL. More...
#define	SAFE_FREE(x)   if(x != NULL) { free(x); x = NULL; }
	Check for non-NULL pointer before freeing it, and then set the pointer to NULL. More...
