		cudaEvent_t	event
	)

inlinestatic

Make future work enqueued to s2 wait on completion of current work enqueued to s1.

Parameters

s1	stream with work that must be completed before future s2 work can begin.
s2	stream whose future work is made to wait on the completion of existing s1 work.
event	used to pass s1 state to s2.
