inline virtual void release(cudaStream_t)

Release asynchronously (only called if can_release_in_callback() returns false)

inline virtual bool can_release_in_callback() const

Returns true if this resource can be released in a host callback without using the stream Resources that return true will be batched together into a single callback to avoid the overhead of creating individual host callbacks for each resource release.

inline virtual void release_in_callback()

Release synchronously on the host (only called if can_release_in_callback() returns true) This will be called from within a batched host callback to minimize callback overhead.
