Description |
|---|---|
Returns the number of activated virtual processor roots and subscribed external threads currently associated with the underlying hardware thread this execution resource represents. |
|
Returns a unique identifier for the hardware thread that this execution resource represents. |
|
Returns a unique identifier for the processor node that this execution resource belongs to. |
|
Returns this execution resource to the Resource Manager. |
Remarks
Execution resources can be standalone or associated with virtual processor roots. A standalone execution resource is created when a thread in your application creates a thread subscription. The methods ISchedulerProxy::SubscribeThread and ISchedulerProxy::RequestInitialVirtualProcessors create thread subscriptions, and return an IExecutionResource interface representing the subscription. Creating a thread subscription is a way to inform the Resource Manager that a given thread will participate in the work queued to a scheduler, along with the virtual processor roots Resource Manager assigns to the scheduler. The Resource Manager uses the information to avoid oversubscribing hardware threads where it can.
