Description
wait_group_events waits for events that identify the
async_work_group_copy
operations to complete. The event objects specified in event_list
will be released after the wait is performed.
This function must be encountered by all work-items in a work-group executing the
kernel with the same num_events and event objects specified in
event_list; otherwise the results are undefined.
This rule applies
to ND-ranges implemented with uniform
and non-uniform work-groups.
Notes
The kernel must wait for the completion of all async copies using the
wait_group_events built-in function before exiting; otherwise the
behavior is undefined.
