void *	allocate (size_t bytes, size_t)
	Allocates `bytes` with cudaMalloc; valid on every stream when this returns. A zero request returns nullptr.
void	deallocate (void *p, size_t, size_t)
	Frees `p` with cudaFree; the caller guarantees that device work touching the memory has completed.

◆ allocate()

void * allocate	(	size_t	bytes,
		size_t	)

inline

Allocates bytes with cudaMalloc; valid on every stream when this returns. A zero request returns nullptr.

◆ deallocate()

void deallocate	(	void *	p,
		size_t	,
		size_t	)

inline

Frees p with cudaFree; the caller guarantees that device work touching the memory has completed.
