This patch adds the ability for an application to request dist-gem5 to begin/ end synchronization using an m5 op. When toggling on sync, all nodes agree on the next sync point based on the maximum of all nodes' ticks. CPUs are suspended until the sync point to avoid sending network messages until sync has been enabled. Toggling off sync acts like a global execution barrier, where all CPUs are disabled until every node reaches the toggle off point. This avoids tricky situations such as one node hitting a toggle off followed by a toggle on before the other nodes hit the first toggle off. |
