I have a machine with two six-core processors (hyper-threading turned off). I understand how to set the affinity for a program using the command line when there is only one processor, but how do you do it for 2 CPUs? Do I just treat it as if I have a single 12-core processor? Or is there some other way to do it?

What options are displayed when you try to change the affinity in Task Manager? What tool / option are you using to set it via the command line, and what does the documentation for that tool say? – Darth Android Sep 20 '12 at 19:38
Please also indicate which operating system and version you are running, in addition to the info Darth Android asked of you. – allquixotic Sep 20 '12 at 21:56
Sorry, this is on Windows 7. I am using the command line in a shortcut link to set the affinity. When I look at processor affinity, I see CPU0 Node 0,1,2,3,4,5 and CPU1 Node 0,1,2,3,4,5. – eek142 Sep 21 '12 at 20:59
