With LP, there are no additional writes to NVMM, no decrease in write endurance, and no performance degradation from cache line flushes and barriers. Persistency failures are discovered using software error detection (checksum), and the system recovers from them by recomputing inconsistent results. LP was evaluated and compared to the state-of-the-art Eager Persistency technique from prior work. Compared to Eager Persistency, LP reduces the execution time and write amplification overheads from 9% and 21% to only 1% and 3%, respectively."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of crash recovery for data stored in non-volatile main memory","description":"Lazy Persistency (LP), a software persistency method that allows caches to slowly send dirty blocks to the non-volatile main memory (NVMM) through natural evictions.
