ProcessThread::IdealProcessor Property

.NET Framework (current version)

Sets the preferred processor for this thread to run on.

Namespace: System.Diagnostics
Assembly: System (in System.dll)

Syntax

public:
[BrowsableAttribute(false)]
property int IdealProcessor {
	void set(int value);
}

Property Value

Type: System::Int32

The preferred processor for the thread, used when the system schedules threads, to determine which processor to run the thread on.

Exceptions

Exception	Condition
Win32Exception	The system could not set the thread to start on the specified processor.
PlatformNotSupportedException	The platform is Windows 98 or Windows Millennium Edition.
NotSupportedException	The process is on a remote computer.

Remarks

The IdealProcessor value is zero-based. In other words, to set the thread affinity for the first processor, set the property to zero.

The system schedules threads on their preferred processors whenever possible.

A process thread can migrate from processor to processor, with each migration reloading the processor cache. Specifying a processor for a thread can improve performance under heavy system loads by reducing the number of times the processor cache is reloaded.

Examples

The following example demonstrates how to set the IdealProcessor property for an instance of Notepad to the first processor.
