Waltz: Temperature-Aware Cooperative Compression for High-Performance Compression-Based CSDs
Dingcui Yu, Yunpeng Song, Yiyang Huang +5
Data compression is widely adopted for modern solid-state drives (SSDs) to mitigate both storage capacity and SSD lifetime issues. Researchers have proposed compression schemes at…
Reducing Memory Contention and I/O Congestion for Disk-based GNN Training
Qisheng Jiang, Lei Jia, Chundong Wang
Graph neural networks (GNNs) gain wide popularity. Large graphs with high-dimensional features become common and training GNNs on them is non-trivial on an ordinary machine. Given…
I/O Transit Caching for PMem-based Block Device
Qing Xu, Qisheng Jiang, Chundong Wang
Byte-addressable non-volatile memory (NVM) sitting on the memory bus is employed to make persistent memory (PMem) in general-purpose computing systems and embedded systems for data…
Sync+Sync: A Covert Channel Built on fsync with Storage
Qisheng Jiang, Chundong Wang
Scientists have built a variety of covert channels for secretive information transmission with CPU cache and main memory. In this paper, we turn to a lower level in the memory hier…
Pome: Parallelizing I/Os and Computations for Efficient LSM-tree-based Data Storage
Yanpeng Hu, Li Zhu, Lei Jia +1
CPU computations and I/O operations are fundamental to data storage systems. Storage systems conduct computations with their user threads, such as sorting data for orderliness. The…
Enabling Atomic Durability for Persistent Memory with Transiently Persistent CPU Cache
Chongnan Ye, Meng Chen, Qisheng Jiang +1
Persistent memory (pmem) products bring the persistence domain up to the memory level. Intel recently introduced the eADR feature that guarantees to flush data buffered in CPU cach…
Accelerating LSM-Tree with the Dentry Management of File System
Yanpeng Hu, Chundong Wang
The log-structured merge tree (LSM-tree) gains wide popularity in building key-value (KV) stores. It employs logs to back up arriving KV pairs and maintains a few on-disk levels wi…
Boosting the Search Performance of B+-tree for Non-volatile Memory with Sentinels
Chongnan Ye, Chundong Wang
The next-generation non-volatile memory (NVM) is striding into computer systems as a new tier as it incorporates both DRAM's byte-addressability and disk's persistency. Researchers…
Reuse Distance-based Copy-backs of Clean Cache Lines to Lower-level Caches
Rui Wang, Chundong Wang, Chongnan Ye
Cache plays a critical role in reducing the performance gap between CPU and main memory. A modern multi-core CPU generally employs a multi-level hierarchy of caches, through which…
Securing Autonomous Service Robots through Fuzzing, Detection, and Mitigation
Chundong Wang, Yee Ching Tok, Rohini Poolat +2
Autonomous service robots share social spaces with humans, usually working together for domestic or professional tasks. Cyber security breaches in such robots undermine the trust b…
STITCHER: Correlating Digital Forensic Evidence on Internet-of-Things Devices
Yee Ching Tok, Chundong Wang, Sudipta Chattopadhyay
The increasing adoption of Internet-of-Things (IoT) devices present new challenges to digital forensic investigators and law enforcement agencies when investigation into cybercrime…
Circ-Tree: A B+-Tree Variant with Circular Design for Persistent Memory
Chundong Wang, Gunavaran Brihadiswarn, Xingbin Jiang +1
Several B+-tree variants have been developed to exploit the performance potential of byte-addressable non-volatile memory (NVM). In this paper, we attentively investigate the prope…
Road Context-aware Intrusion Detection System for Autonomous Cars
Jingxuan Jiang, Chundong Wang, Sudipta Chattopadhyay +1
Security is of primary importance to vehicles. The viability of performing remote intrusions onto the in-vehicle network has been manifested. In regard to unmanned autonomous cars,…
