About the Event

Emerging storage technologies offer an alternative to disk that is durable and accelerates data access. However, new nonvolatile memories (NVRAM) such as flash and phase change memory used merely as a disk replacement fail to achieve their full potentials. Flash's asymmetric read/write access (i.e., reads execute faster than writes) opens new opportunities to optimize flash-specific access. Similarly, NVRAM's low latency persistent accesses enable new designs for high performance failure-resistant applications. My dissertation addresses several storage-critical applications that stand to benefit from new NVRAMs. First, I investigate analytics query optimization for flash. Second, I examine new opportunities for durable, recoverable transaction processing with NVRAM. Finally, I propose a new framework for persistent programming and memory systems to enable high performance recoverable data structures with NVRAM, extending memory consistency with persistent semantics to introduce memory persistency.
