A surprising development in recently announced HPC platforms is the addition of, sometimes massive amounts of, persistent (nonvolatile) memory (NVM) in order to increase memory capacity and compensate for plateauing I/O capabilities. However, there are no portable and scalable programming interfaces using aggregate NVM effectively. This paper introduces Papyrus: a new software system built to exploit...
Modern Non-Volatile Memory (NVM) promises persistence, byte-addressability and DRAM-like read and write latency, which offers great opportunities for big data storage architecture. These excellent properties indicate that NVM has the potential to be incorporated with key-value stores to achieve high performance and durability simultaneously. In this paper, we propose an efficient key-value storage...
Non-volatile memory is a promising material that covers both cache and secondary storage in a memory hierarchy. Many software platforms exploiting non-volatile have been developed and provide user-level programming interfaces. However, common programs cannot allocate non-volatile memory. In this paper, we introduce a code generation method for HEAPO that is one of non-volatile memory software platforms...
Emerging byte-addressable nonvolatile memories (NVMs) promise persistent memory, which allows processors to directly access persistent data in main memory. Yet, persistent memory systems need to guarantee a consistent memory state in the event of power loss or a system crash (i.e., crash consistency). To guarantee crash consistency, most prior works rely on programmers to (1) partition persistent...
