摘要：PCM is rapidly evolved as a promising candidate for subsequent-technology storage class reminiscence(SCM) because of its non-volatility, byte-addressability, and high get admission to overall performance. In recent years,researchers have studied the way to use PCM as primary memory or hybrid fundamental reminiscence to improve thegadget overall performance and power efficiency. Although some research has explored the read/write asymmetry ofPCM to further optimize the performance of PCM, the use of PCM as important memory suffers from the writeendurance issue. As for the gap usage of record machine designs, some of previous research proposed different controldesigns to enhance the space utilization of file systems over block-primarily based garage devices. However, to thehigh-quality of our knowledge, little research has been executed trying to optimize the gap utilization of record systemsthrough taking gain of the best features of PCM. In this paper we suggest a multi-grained block management approachto improve the space usage of report structures over PCM-based storage systems with minimized space and controloverheads.
