Partly because of the new Mac Pros (with two processors sharing a
single cache) I was trying to figure whether the Darwin scheduler
takes special provisions to keep threads on the same physicial "die
package" (so the common cache can be reused). From looking at the xnu-
source, I thought this might've been solved using more than one
"processor_set"; but it seems there is only a single set from what I
can see.
Does anyone have further information on this or can point to a
particular area of the xnu-source that's worth investigating?
Thanks,
Daniel.
