摘要:
Emergence of new hardware,including persistent memory and smart network interface card(SmartNIC),has brought new opportunities to file system *** this paper,we design and implement a new file system named NICFS based on persistent memory and *** divide the file system into two parts:the front end and the back *** the front end,data writes are appended to the persistent memory in a log-structured way,leveraging the fast persistence advantage of persistent *** the back end,the data in logs are fetched,processed,and patched to files in the background,leveraging the processing capacity of *** results show that NICFS outperforms Ext4 by about 21%/10%and about 19%/50%on large and small reads/writes,respectively.
