With the fast development of highly integrated distributed systems (cluster systems), especially those encapsulated within a single platform [28, 9], designers have to face interesting memory hierarchy design choices that attempt to avoid disk storage swapping. Disk swapping activities slow down application execution drastically. Leveraging remote free memory through Memory Collaboration has demonstrated its cost-effectiveness compared to overprovisioning for peak load requirements. Recent studies propose several ways on accessing the under-utilized remote memory in static system configurations, without detailed exploration on the dynamic memory collaboration. Dynamic collaboration is an important aspect given the run-time memory usage fluctuations in clustered systems.
