However, most of this work has focused on\r\nconcurrent data structures providing good \\emph{worst-case} guarantees. In real\r\nworkloads, objects are often accessed at different rates, since access\r\ndistributions may be non-uniform. Efficient distribution-adaptive data\r\nstructures are known in the sequential case, e.g. the splay-trees; however,\r\nthey often are hard to translate efficiently in the concurrent case.\r\n  In this paper, we investigate distribution-adaptive concurrent data\r\nstructures and propose a new design called the splay-list. At a high level, the\r\nsplay-list is similar to a standard skip-list, with the key distinction that\r\nthe height of each element adapts dynamically to its access rate: popular\r\nelements ``move up,'' whereas rarely-accessed elements decrease in height. We\r\nshow that the splay-list provides order-optimal amortized complexity bounds for\r\na subset of operations while being amenable to efficient concurrent\r\nimplementation. Experimental results show that the splay-list can leverage\r\ndistribution-adaptivity to improve on the performance of classic concurrent\r\ndesigns, and can outperform the only previously-known distribution-adaptive\r\ndesign in certain settings."}],"oa":1,"oa_version":"Published Version","series_title":"LIPIcs","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2020-11-05T15:26:17Z","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","quality_controlled":"1","title":"The splay-list: A distribution-adaptive concurrent skip-list","status":"public"}
