Configure the CPU Setup Page

The CPU Setup page of the Setup Wizard is used to assign client and server components to specific processors on a multi-processor computer.

The page includes a table that identifies each Component (and the cluster to which it belongs), its Priority and its CPU assignment.

• If the Multi-process option was selected on the Computer Role Setup page, you can select specific CPUs for the Client, I/O Server, Alarm Server, Trends Server and Reports Server processes.

• If the Multi-process option was not selected, there will only be one entry listed. It will either be “Client” or “Client and Servers”.

To assign a CPU to a component:

1. Select one or more components from the list (hold the Ctrl key down to select multiple components).

2. Click the Modify button.

3. Select the CPUs you want to assign to the component (you can select more than one) or select <All CPUs>.

4. Click OK.

When you complete the Setup Wizard, the CPU assignations are written to each component section in the INI file; for example:

...
[Alarm.Cluster1.AlarmServer1]
CPU=1
Clusters=Cluster1
...
[Trend.Cluster1.TrendServer1]
CPU=2
Clusters=Cluster1
...
If ALL is selected, the component sections in the INI file will be left empty and the processes will run on all CPUs.

In situations where ALL is selected, be aware that performance issues may still occur when your CPU usage is less than 100%. You can detect these issues when your CPU usage for a process is fixed at 100 divided by the number of processors.

Note: If a computer has more than 32 CPUs, the CPU Setup page in Setup Wizard will be disabled. The component sections in the INI file will be left empty and the processes will run on all CPUs.
