The Microsoft Interrupt-Affinity Policy Tool (IntPolicy) is a software that allows you to "bind" or change the CPU affinity of the interrupts for a given device (such as a network adapter or GPU) to a specific CPU core, processor or processors on a multiprocessor computer. ...
I have a driver that sets the interrupt affinity mask in HKLM\SYSTEM\CurrentControlSet\Enum\PCI\PNPID]\ID]\Device Parameters\Interrupt Management\Affinity Policy - Temporal . The key contains TargetSet (QWORD) and TargetGroup (DWORD). When I select that device in the Interrupt Policy Configurati...

The affinity of an interrupt is the set of processors that can service the interrupt. Each device has an affinity policy. The operating system uses the affinity policy to compute the affinity for that device's interrupts. The affinity policy can be specified in the device's INF file or regis...

from the previous execution of the thread. Applications can restrict threads to run only on certain processors (this is calledhard affinity), but this is rare. In addition, Task Manager, a tool built into Windows NT 4.0 Workstation and Server, lets you determine which processor runs a ...
