That's the other one, sometimes called CMM-2. It's a cool research project. It requires hardware support as well as Linux kernel changes to allow Linux memory management share information with VM memory management. Without the hardware support it might be pretty expensive, depending on the workload. The idea is that this should do automatic tuning with no need for knobs to turn. Last I heard was that "it is possible to construct artificial workloads in a lab environment that demonstrate it to be very effective" But to understand what this means for real business workload requires proper performance measurements. I have not seen any measurements published.
