Namespace: Microsoft.Hpc.Scheduler.Session.SessionStartInfo
Assembly: Microsoft.Hpc.Scheduler.Session (in Microsoft.Hpc.Scheduler.Session.dll)

Usage

'Usage
Dim instance As BrokerSettingsInfo
Dim value As Nullable(Of Integer)

value = instance.AllocationShrinkLoadRatioThreshold

instance.AllocationShrinkLoadRatioThreshold = value

/** @property */
public void set_AllocationShrinkLoadRatioThreshold (Nullable<int> value)

public function get AllocationShrinkLoadRatioThreshold () : Nullable<int>

public function set AllocationShrinkLoadRatioThreshold (value : Nullable<int>)

Property Value

The lower threshold. The default is 75 percent.

Remarks

The number of service instances that the broker can initiate on the server (capacity) can grow and shrink based on the client activity (message requests). If the current load (the ratio of pending requests to available capacity) falls below this threshold, the broker shrinks the service capacity until the load ratio falls within the AllocationShrinkLoadRatioThreshold and AllocationGrowLoadRatioThreshold range.

You must cast the value to an integer. If the value is null (a null value means that the value has not been set and the broker is using the default value set in the configuration file), the cast raises an exception.

Platform Note: For Windows HPC Server 2008 R2, this property is obsolete and no longer takes effect.

Thread Safety
