Syntax

<Thread_UseAllCpuGroups
   enabled="true|false"/>

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description
`enabled`	Required attribute. Specifies whether the runtime distributes managed threads across all CPU groups.

enabled Attribute

Value	Description
`false`	The runtime does not distribute managed threads across multiple CPU groups. This is the default.
`true`	The runtime distributes managed threads across multiple CPU groups, if the computer has multiple CPU groups and the <GCCpuGroup> element is enabled.

Child Elements

None.

Parent Elements

Element	Description
`configuration`	The root element in every configuration file used by the common language runtime and .NET Framework applications.
`runtime`	Contains information about assembly binding and garbage collection.

Remarks

When a computer has multiple CPU groups, enabling this element causes the runtime to distribute managed threads across all CPU groups. To use this feature, you must also enable the <GCCpuGroup> element, which extends garbage collection to all CPU groups and takes all cores into account when creating and balancing heaps. Enabling the <GCCpuGroup> element requires enabling the <gcServer> element. If these elements are not enabled, enabling the <Thread_UseAllCpuGroups> element has no effect.

Example

The following example shows how to enable support for multiple CPU groups.

<configuration>
   <runtime>
      <Thread_UseAllCpuGroups enabled="true"/>
      <GCCpuGroup enabled="true"/>
      <gcServer enabled="true"/>
   </runtime>
</configuration>
