IExecutionResource Structure

An abstraction for a hardware thread.

struct IExecutionResource;

Members

Public Methods

Name	Description
IExecutionResource::CurrentSubscriptionLevel Method	Returns the number of activated virtual processor roots and subscribed external threads currently associated with the underlying hardware thread this execution resource represents.
IExecutionResource::GetExecutionResourceId Method	Returns a unique identifier for the hardware thread that this execution resource represents.
IExecutionResource::GetNodeId Method	Returns a unique identifier for the processor node that this execution resource belongs to.
IExecutionResource::Remove Method	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.
