OCTO+: Optimized Checkpointing of B+ Trees for Non-Volatile Main Memory Wear-Leveling

Steady deployment of byte addressable non-volatile memories (NVMs) as main memory in server class computers yields challenges on software. In order to overcome shortcomings, as for instance low cell endurance and high access latencies, working data can be kept in DRAM and continuously be checkpointed to the NVM. Although this reduces the impact of the NVM on usual execution, it shifts the enduranc...
