For an execution of n events over k threads and d variables, we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k· d) for PSO. Moreover, based on our solution to these problems, we develop an SMC algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal, in the sense that it is guaranteed to explore each class of the RF partitioning exactly once, and spends polynomial time per class when k is bounded. Finally, we implement all our algorithms in the SMC tool Nidhugg, and perform a large number of experiments over benchmarks from existing literature. Our experimental results show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO, which yields a significant speedup in the model checking task.\r\n\r\n"}],"oa":1,"date_created":"2021-10-27T15:05:34Z","publication_identifier":{"eissn":["2475-1421"]},"intvolume":"         5","publisher":"Association for Computing Machinery","author":[{"last_name":"Bui","full_name":"Bui, Truc Lam","first_name":"Truc Lam"},{"orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Gautam, Tushar","last_name":"Gautam","first_name":"Tushar"},{"first_name":"Andreas","id":"49704004-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8943-0722","full_name":"Pavlogiannis, Andreas","last_name":"Pavlogiannis"},{"first_name":"Viktor","id":"3AF3DA7C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9036-063X","full_name":"Toman, Viktor","last_name":"Toman"}],"publication_status":"published","date_updated":"2023-09-07T13:30:27Z","has_accepted_license":"1","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"file_date_updated":"2021-11-04T07:24:48Z","file":[{"file_id":"10215","relation":"main_file","date_created":"2021-11-04T07:24:48Z","checksum":"9d6dce7b611853c529bb7b1915ac579e","success":1,"date_updated":"2021-11-04T07:24:48Z","access_level":"open_access","file_size":2903485,"file_name":"2021_ProcACMPL_Bui.pdf","content_type":"application/pdf","creator":"cchlebak"}],"article_number":"164","ec_funded":1,"language":[{"iso":"eng"}],"_id":"10191","month":"10","quality_controlled":"1","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","day":"15"}
