"Verifying and Optimizing Compact NUMA-Aware Locks on Weak Memory Models"

[Paul E. McKenney]

Hello!

I have not yet done more than glance at this one, but figured I should
send it along sooner rather than later.

"Verifying and Optimizing Compact NUMA-Aware Locks on Weak
Memory Models", Antonio Paolillo, Hernán Ponce-de-León, Thomas
Haas, Diogo Behrens, Rafael Chehab, Ming Fu, and Roland Meyer.

The claim is that the queued spinlocks implementation with CNA violates
LKMM but actually works on all architectures having a formal hardware
memory model.

Thoughts?

							Thanx, Paul
