主　　题：Page table Hybrid memory system Page migration Multiple page sizes Address translation 

摘      要：Page migration has long been adopted in hybrid memory systems comprising dynamic random access memory(DRAM)and non-volatile memories(NVMs),to improve the system performance and energy ***,page migration introduces some side effects,such as more translation lookaside buffer(TLB)misses,breaking memory contiguity,and extra memory accesses due to page table *** this paper,we propose superpagefriendly page table called SuperPT to reduce the performance overhead of serving TLB *** leveraging a virtual hashed page table and a hybrid DRAM allocator,SuperPT performs address translations in a flexible and efficient way while still remaining the contiguity within the migrated pages.
