65  * processes in sync.
66  * Periodic barrier event to keep peer gem5 processes in sync. The basic idea
113      * This class implements global sync operations among gem5 peer processes.
137          * Flag is set if exit is permitted upon sync completion
141          * Flag is set if taking a ckpt is permitted upon sync completion
145          * Flag is set if sync is to stop upon sync completion
149          * The repeat value for the next periodic sync
153          * Tick for the next periodic sync (if the event is not scheduled yet)
157          *  Flag is set if the sync is aborted (e.g. due to connection lost)
165          * Initialize periodic sync params.
173          *  Core method to perform a full dist sync.
175          * @return true if the sync completes, false if it gets aborted
179          * Callback when the receiver thread gets a sync ack message.
190          * Abort processing an on-going sync event (in case of an error, e.g.
252          * Counter for recording stop sync requests
278             panic("Switch requested stop sync");
286      * The global event to schedule periodic dist sync. It is used as a
295      * complete the ongoing barrier. The global sync event is done.
313          * Schedule the first periodic sync event.
455      * Tick to schedule the first dist sync event.
456      * This is just as optimization : we do not need any dist sync
461      * Frequency of dist sync events in ticks.
