NBTree: a Lock-free PM-friendly Persistent B+-Tree for eADR-enabled PM Systems
Proceedings of the VLDB Endowment, 2022Persistent memory (PM) promises near-DRAM performance as well as data persistency. Recently, a new feature called eADR is available on the 2 nd generation Intel Optane PM with the 3 rd generation Intel Xeon Scalable Processors. eADR ensures

Mirror: making lock-free data structures persistent
ACM-SIGPLAN Symposium on Programming Language Design and Implementation, 2021With the recent launch of the Intel Optane memory platform, non-volatile main memory in the form of fast, dense, byte-addressable non-volatile memory has now become available.

Detectable recovery of lock-free data structures
ACM SIGPLAN Symposium on Principles & Practice of Parallel Programming, 2022This paper presents a generic approach for deriving detectably recoverable implementations of many widely-used concurrent data structures. Such implementations are appealing for emerging systems featuring byte-addressable non-volatile main memory (NVMM),

CHTKC: a robust and efficient k-mer counting algorithm based on a lock-free chaining hash table
Briefings Bioinform., 2020MOTIVATION Calculating the frequency of occurrence of each substring of length k in DNA sequences is a common task in many bioinformatics applications, including genome assembly, error correction, and sequence alignment.

Lock-free transactional vector
Proceedings of the Eleventh International Workshop on Programming Models and Applications for Multicores and Manycores, 2020The vector is a fundamental data structure, offering constant-time traversal to elements and a dynamically resizable range of indices. While several concurrent vectors exist, a composition of concurrent vector operations dependent on each other can lead to undefined behavior.

Locking-Free Degenerated Isoparametric Shell Element
Applied Mathematics and Mechanics, 2001An 8-noded locking-free degenerated isoparametric shell element is presented. A revised interpolation for shear strain terms was constructed in natural co-ordinate system such that all necessary modes (translation, rotation and constant curvature) are preserved, which can be used to eliminate shear locking.

Proceedings of the third international symposium on Memory management - ISMM '02, 2002
Modern multithreaded applications, such as application servers and database engines, can severely stress the performance of user-level memory allocators like the ubiquitous malloc subsystem. Such allocators can prove to be a major scalability impediment for the applications that use them, particularly for applications with large numbers of threads ...

2014 IEEE 34th International Conference on Distributed Computing Systems, 2014
This paper presents a lock-free cuckoo hashing algorithm, to the best of our knowledge this is the first lock-free cuckoo hashing in the literature. The algorithm allows mutating operations to operate concurrently with query ones and requires only single word compare-and-swap primitives.

A Scalable, Portable, and Memory-Efficient Lock-Free FIFO Queue
International Symposium on Distributed Computing, 2019We present a new lock-free multiple-producer and multiple-consumer (MPMC) FIFO queue design which is scalable and, unlike existing high-performant queues, very memory efficient.
