Evaluating Dynamics and Bottlenecks of Memory Collaboration in Cluster Systems

With the fast development of highly-integrated distributed systems (cluster systems), designers face interesting memory hierarchy design choices while attempting to avoid the notorious disk swapping. Swapping to the free remote memory through Memory Collaboration has demonstrated its cost-effectiveness compared to over-provisioning the cluster for peak load requirements. Recent memory collaboration studies propose several ways on accessing the under-utilized remote memory in static system configurations, without detailed exploration of the dynamic memory collaboration. Dynamic collaboration is an important aspect given the run-time memory usage fluctuations in clustered systems. Further, as the interest in memory collaboration grows, it is crucial to understand the existing performance bottlenecks, overheads, and potential optimization.
