CPU Configuration

Projects > Run a Project Using the Setup Wizard > CPU Configuration

The CPU Setup page is used to assign client and server components to specific processors in a multi-processor machine.

This page lists each component's full name, including the cluster to which it belongs, the priority and the CPU assignment. If the multi-process option was not selected on the Computer Role Configuration page there will only be one entry listed, either Client or Client and Servers. If the Multi-process option was selected, you have the option of selecting specific CPUs for the Client, I/O Server, Alarm Server, Trends Server and Reports Server.

To assign a CPU to a component:

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

Note: In some situations, when 'All' processes is selected under "Modify CPU Configuration" windows in the Setup Wizard, 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 your number of processors.

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
...
