Default process placement policy

The system provides a default process placement policy that takes effect for all processes. By default, the default process placement policy defines the following rules:

• (In standalone mode.) The active process runs on the CPU of the active MPU, and the standby processes run on the CPU of the standby MPU.

• (In IRF mode.) The active process runs on the CPU of the global active MPU, and the standby processes run on the CPU of the global standby MPU.

• A process runs at the location where it ran the last time and does not move to any other location during startup or operation.

• The addition of a new node does not impact current active processes. A new active process selects one node with sufficient CPU and memory resources. (You can use the display cpu-usage and display memory commands to view CPU and memory usage information.)

You can modify the default placement policy in the view you enter by using the placement program default command. You can also configure a placement policy for a specific process in the view you enter by using the placement program program-name [ instance instance-name ] command. A placement policy for a process takes precedence over the default process placement policy.
