Kentsfield / Yorkfield on Linux

[drwowe]

I have a question that I haven't seen answered anywhere. Is the Linux scheduler aware of the SMP dual core architecture of these processors? IOW, is it smart enough to know that bouncing processes between cores on separate dies is a lot more expensive that moving from one core to the other on the same die?

I run a lot of CPU bound stuff. I could set CPU affinity manually, but I'd rather let the OS take care of it unless it's making stupid decisions.

A quick search yielded these super olde links, so I feel it is safe to assume the kernel is numa aware.
