XcalableMP Programming Model and Language

xmpt_event_sync_images_all_end
xmpt_event_sync_images_begin
xmpt_event_sync_images_end
When one of the XMPT events for which callbacks are registered occurs at
runtime, the corresponding callback is invoked by the XMP runtime. For example,
if callbacks are registered for events xmpt_event_bcast_begin and xmpt_
event_bcast_end as in the example in the previous section, the callbacks
callback_bcast_begin and callback_bcast_end are invoked immediately before and after each of bcast constructs, respectively.
The XMP runtime passes therein all the information about the construct, including the mapping of the target global arrays, to the callback as its parameters. Thus,
the tool is able to extract necessary information from the arguments.
