Leader: Accelerating ReRAM-based main memory by leveraging access latency discrepancy in crossbar arrays
TLDR
An asymmetric ReRAM memory design is presented, which separates a crossbar array into multiple logical regions according to their access latency, and further groups logical regions across different crossbars into virtual regions, and introduces both static mapping and dynamic mapping schemes to prioritize memory requests from critical applications to the fast regions for better performance.

Architecting energy-efficient STT-RAM based register file on GPGPUs via delta compression
TLDR
This paper proposes to optimize STT-RAM based GPU register files for better energy-efficiency and performance via two techniques, including a light-weight compression framework with awareness of register value similarity and a centralized SRAM-based write buffer design to address the long write latency overhead.

HConfig: Resource adaptive fast bulk loading in HBase
TLDR
HConfig, a semi-automated configuration manager for optimizing HBase system performance from multiple dimensions is developed and it is shown that the HConfig enhanced bulk loading can significantly improve the performance of HBase bulk loading jobs compared to the HBase default configuration, and achieve 2.7× speedup in throughput under different client threads while maintaining linear horizontal scalability.

Redesign the Memory Allocator for Non-Volatile Main Memory
TLDR
WAlloc is proposed, an efficient wear-aware manual memory allocator designed for NVRAM that decouples metadata and data management, redesigns an efficient and effective NVM copy mechanism, bypassing the CPU cache partially and prefetching data explicitly.
