That is weird. If I understand the intel doc <https://software.intel.com/sites/default/files/managed/8b/6e/335279_performance_monitoring_events_guide.pdf?ref=hvper.com> correctly, both these names refer to the same event (`EventSel=A1H, UMask=01H`). I have a haswell machine and `dispatched` worked (but I patched your change and I get the exact same results, which is to be expected given that the event is the same). What version of libpfm do you have ? I've seen both work on`4.10.1+git14-g815ff28-1`.
