In this paper, we consider the time complexity of this problem when the namespace is linear in the number of participants, a variant known as loose renaming. We give a non-adaptive algorithm with O(log log n) (individual) step complexity, where n is a known upper bound on contention, and an adaptive algorithm with step complexity O((log log k)2), where k is the actual contention in the execution. We also present a variant of the adaptive algorithm which requires O(k log log k) total process steps. All upper bounds hold with high probability against a strong adaptive adversary. We complement the algorithms with an ω(log log n) expected time lower bound on the complexity of randomized renaming using test-and-set operations and linear space. The result is based on a new coupling technique, and is the first to apply to non-adaptive randomized renaming. Since our algorithms use O(n) test-and-set objects, our results provide matching bounds on the cost of loose renaming in this setting."}],"date_updated":"2023-02-23T13:13:14Z","publist_id":"6889","oa_version":"None","conference":{"name":"PODC: Principles of Distributed Computing"},"author":[{"last_name":"Alistarh","first_name":"Dan-Adrian","orcid":"0000-0003-3650-940X","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","full_name":"Alistarh, Dan-Adrian"},{"first_name":"James","last_name":"Aspnes","full_name":"Aspnes, James"},{"full_name":"Giakkoupis, George","last_name":"Giakkoupis","first_name":"George"},{"full_name":"Woelfel, Philipp","last_name":"Woelfel","first_name":"Philipp"}],"status":"public","date_created":"2018-12-11T11:48:23Z"}
