Concurrent Deterministic Skiplist and Other Data Structures
share
Skiplists are used in a variety of applications for storing data subject to order criteria. In this article we discuss the design, analysis and performance of a concurrent deterministic skip list on many-core NUMA nodes. We also evaluate the performance of a concurrent lock-free unbounded queue implementation and three implementations of multi-writer, multi-reader (MWMR) hash tables and compare their performance with equivalent implementations from Intel's Thread Building Blocks (TBB) library. We focus on strategies for memory management that reduce page faults and cache misses for the memory access patterns in these data structures. This paper proposes hierarchical usage of concurrent data structures in programs to improve memory latencies by reducing memory accesses from remote NUMA nodes.
