I don't know. But I do know that processor/thread binding (if that is 
what you mean by "pin") is *extremely* important in Sandy Bridge, even 
more than on previous archs. And, oddly enough, in my experience is more 
difficult to get it right than on previous arch.

Unfortunately, the runtime I have most experience with is very different 
from the standard gcc-pthreads-fork which I believe would be relevant 
here, so my experience is useless in this context.

Good luck finding the way to do this right, keep us posted!
