Additional Inherited Members | |
| Public Types inherited from EventBase | |
| typedef int8_t | Priority |
| Static Public Member Functions inherited from Serializable | |
| static const std::string & | currentSection () |
| Get the fully-qualified name of the active section. More... | |
| static void | serializeAll (const std::string &cpt_dir) |
| static void | unserializeGlobals (CheckpointIn &cp) |
| Static Public Attributes inherited from EventBase | |
| static const Priority | Minimum_Pri = SCHAR_MIN |
| Event priorities, to provide tie-breakers for events scheduled at the same cycle. More... | |
| static const Priority | Debug_Enable_Pri = -101 |
| If we enable tracing on a particular cycle, do that as the very first thing so we don't miss any of the events on that cycle (even if we enter the debugger). More... | |
| static const Priority | Debug_Break_Pri = -100 |
| Breakpoints should happen before anything else (except enabling trace output), so we don't miss any action when debugging. More... | |
| static const Priority | CPU_Switch_Pri = -31 |
| CPU switches schedule the new CPU's tick event for the same cycle (after unscheduling the old CPU's tick event). More... | |
| static const Priority | Delayed_Writeback_Pri = -1 |
| For some reason "delayed" inter-cluster writebacks are scheduled before regular writebacks (which have default priority). More... | |
| static const Priority | Default_Pri = 0 |
| Default is zero for historical reasons. More... | |
| static const Priority | DVFS_Update_Pri = 31 |
| DVFS update event leads to stats dump therefore given a lower priority to ensure all relevant states have been updated. More... | |
| static const Priority | Serialize_Pri = 32 |
| Serailization needs to occur before tick events also, so that a serialize/unserialize is identical to an on-line CPU switch. More... | |
| static const Priority | CPU_Tick_Pri = 50 |
| CPU ticks must come after other associated CPU events (such as writebacks). More... | |
| static const Priority | Stat_Event_Pri = 90 |
| Statistics events (dump, reset, etc.) come after everything else, but before exit. More... | |
| static const Priority | Progress_Event_Pri = 95 |
| Progress events come at the end. More... | |
| static const Priority | Sim_Exit_Pri = 100 |
| If we want to exit on this cycle, it's the very last thing we do. More... | |
| static const Priority | Maximum_Pri = SCHAR_MAX |
| Maximum priority. More... | |

The base class for the local events that will synchronize threads to perform the global event.
This class is abstract, since it derives from the abstract Event class but still does not define the required process() method.

If this is part of a GlobalEvent, return the pointer to the Global Event.
By default, there is no GlobalEvent, so return NULL. (Overridden in GlobalEvent::BarrierEvent.)
Reimplemented from Event.
