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.

A novel NVM memory file system for edge intelligence

“…In addition, storing key persistent information such as the weights of deep neural network (DNN) in NNM can avoid the delay and power consumption caused by the movement of data between memory and external storage. Among the emerging new-generation NVMs, phase change memory (PCM) has the characteristics of high access speed, high density, lower power consumption and compatibility with CMOS, making it suitable for edge hybrid memory [14,15,16,17,18]. The non-volatility and byte addressability of the emerging NVMs make traditional management methods no longer applicable.…”
