Set agreement has been extensively studied in both synchronous and asynchronous systems [10,11,3,5,8,9]. Real world distributed systems, however, are neither purely synchronous nor purely asynchronous. To describe such a system, Dwork et al. [6] introduced the idea of partial synchrony. They assume for every execution some (unknown) time GST (global stabilization time), after which the system is synchronous. In a recent paper [1,2], we study the complexity of set agreement in the context of partially synchronous systems, determining the minimum-sized window of synchrony in which set agreement can be solved. We show that at least ⌊t/k⌋ + 2 synchronous rounds are required for k-set agreement, where t &lt; n is the number of crashes, and k is the agreement parameter of the set agreement task. We then introduce an algorithm that terminates in any window of synchrony of size at least ⌊t/k⌋ + 4 rounds. Together, these results tightly bound the inherent price of tolerating some asynchrony."}],"_id":"758","language":[{"iso":"eng"}],"day":"01","author":[{"last_name":"Alistarh","first_name":"Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","full_name":"Alistarh, Dan-Adrian","orcid":"0000-0003-3650-940X"},{"last_name":"Gilbert","first_name":"Seth","full_name":"Gilbert, Seth"},{"first_name":"Rachid","last_name":"Guerraoui","full_name":"Guerraoui, Rachid"},{"last_name":"Travers","first_name":"Corentin","full_name":"Travers, Corentin"}],"doi":"10.1007/978-3-642-15763-9_40","page":"404 - 405","type":"conference","date_updated":"2023-02-23T13:11:26Z","article_processing_charge":"No","month":"01"}
