However, most of this work has focused on concurrent data structures providing good worst-case guarantees, although, in real workloads, objects are often accessed at different rates. Efficient distribution-adaptive data structures, such as splay-trees, are known in the sequential case; however, they often are hard to translate efficiently to the concurrent case. We investigate distribution-adaptive concurrent data structures, and propose a new design called the splay-list. At a high level, the splay-list is similar to a standard skip-list, with the key distinction that the height of each element adapts dynamically to its access rate: popular elements “move up,” whereas rarely-accessed elements decrease in height. We show that the splay-list provides order-optimal amortized complexity bounds for a subset of operations, while being amenable to efficient concurrent implementation. Experiments show that the splay-list can leverage distribution-adaptivity for performance, and can outperform the only previously-known distribution-adaptive concurrent design in certain workloads."}],"year":"2023","publisher":"Springer Nature","status":"public","article_type":"original","department":[{"_id":"DaAl"}],"oa_version":"Preprint","type":"journal_article","citation":{"mla":"Aksenov, Vitalii, et al. “The Splay-List: A Distribution-Adaptive Concurrent Skip-List.” <i>Distributed Computing</i>, vol. 36, Springer Nature, 2023, pp. 395–418, doi:<a href=\"https://doi.org/10.1007/s00446-022-00441-x\">10.1007/s00446-022-00441-x</a>.","ama":"Aksenov V, Alistarh D-A, Drozdova A, Mohtashami A.
