Efficient management of PCM-based swap storage

Abstract

This letter explores the performance of PCM-based swap storage and presents three management techniques. First, we attach PCM on DIMM slots to eliminate block I/O overhead and remove the context switching process while handling page faults. Second, we reduce the page size and turn off the read-ahead option to consider the high performance characteristics of PCM. Third, we decrease the DRAM memory size to save energy consumption without sacrificing the performance.
