Under Windows NT, on a multi-processor box, is it possible to run copies of an application on each processor? Is is possible to specify which processor an application should run on? If I wrote a Photoshop plug-in filter, could I have it spawn off little daemon-like filtering engines, one on each available processor? Just curious if the capability is there, or if processors are handed out by the OS.
