One goal of Chorus is to express the dynamic and instance-dependent patterns of memory access that are common in typical irregular applications. Its other focus is locality of effects: the property that in many of the same applications, typical imperative commands only affect small, local regions in the shared heap.\r\nChorus addresses dynamism and locality through the unifying abstraction of an object assembly: a local region in a shared data structure equipped with a short-lived, speculative thread of control. The thread of control in an assembly can only access objects within the assembly. While objects can migrate from assembly to assembly, such migration is local--i.e., objects only move from one assembly to a neighboring one--and does not lead to aliasing. Programming primitives include a merge operation, by which an assembly merges with an adjacent assembly, and a split operation, which splits an assembly into smaller ones. Our abstractions are race and deadlock-free, and inherently data-centric.\r\nWe demonstrate that Chorus and JChorus allow natural programming of several important applications exhibiting irregular data-parallelism. We also present an implementation of JChorus based on a many-to-one mapping of assemblies to lower-level threads, and report on preliminary performance numbers.","lang":"eng"}],"publication_status":"published","doi":"10.1145/1639949.164009","title":"Parallel programming with object assemblies","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"10","publist_id":"1083","volume":44,"publication":"ACM SIGPLAN Notices","page":"61 - 80","language":[{"iso":"eng"}],"citation":{"short":"R.

These assumptions are often violated in realistic settings, as STM implementations run on relaxed memory models, with the atomicity of operations as provided by the hardware. This paper presents the first approach to verify STMs under relaxed memory models with atomicity of 32 bit loads and stores, and read-modify-write operations. We present RML, a new high-level language for expressing concurrent algorithms with a hardware-level atomicity of instructions, and whose semantics is parametrized by various relaxed memory models. We then present our tool, FOIL, which takes as input the RML description of an STM algorithm and the description of a memory model, and automatically determines the locations of fences, which if inserted, ensure the correctness of the STM algorithm under the given memory model. We use FOIL to verify DSTM, TL2, and McRT STM under the memory models of sequential consistency, total store order, partial store order, and relaxed memory order.","lang":"eng"}],"publication_status":"published","intvolume":"      5643","doi":"10.1007/978-3-642-02658-4_26","type":"conference","quality_controlled":0,"author":[{"last_name":"Guerraoui","full_name":"Guerraoui, Rachid","first_name":"Rachid"},{"full_name":"Thomas Henzinger","last_name":"Henzinger","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000−0002−2985−7724"},{"first_name":"Vasu","id":"4DAE2708-F248-11E8-B48F-1D18A9856A87","full_name":"Vasu Singh","last_name":"Singh"}],"oa":1,"date_published":"2009-06-19T00:00:00Z","date_updated":"2021-01-12T07:56:34Z","year":"2009","alternative_title":["LNCS"]},{"day":"10","publisher":"ACM","scopus_import":"1","_id":"4385","extern":"1","language":[{"iso":"eng"}],"citation":{"ama":"Dragojevic A, Guerraoui R, Singh A, Singh V.

This paper explores a complementary approach that prevents conflicts by scheduling transactions according to predictions on their access sets.\r\nWe first explore the theoretical boundaries of this approach and prove that (1) a TM scheduler with an accurate prediction can be 2-competitive with an optimal offline TM scheduler, but (2) even a slight inaccuracy in prediction makes the competitive ratio of the TM scheduler in the order of the number of transactions.\r\nWe then show that, in practice, there is room for a pragmatic approach with good average case performance. We present Shrink, a scheduler that (1) bases its prediction of transactional accesses on the access patterns of the past transactions from the same thread, and (2) uses a novel heuristic, which we call serialization affinity, to schedule transactions with a probability proportional to the current amount of contention. Shrink obtains roughly 70% accurate read and write access predictions on STMBench7 and STAMP. In our experimental evaluation, Shrink significantly improves STM performance in cases the number of executing threads is higher than the number of available CPU cores. For SwissTM, Shrink improves the performance by up to 55% on STMBench7, and up to 120% on STAMP. For TinySTM, Shrink drastically improves the performance on STMBench7 and STAMP benchmarks.","lang":"eng"}],"publication_status":"published","status":"public","year":"2009","date_updated":"2025-07-02T06:35:49Z","date_published":"2009-08-10T00:00:00Z","article_processing_charge":"No","author":[{"full_name":"Dragojevic, Aleksandar","last_name":"Dragojevic","first_name":"Aleksandar"},{"first_name":"Rachid","full_name":"Guerraoui, Rachid","last_name":"Guerraoui"},{"first_name":"Anmol","last_name":"Singh","full_name":"Singh, Anmol"},{"id":"4DAE2708-F248-11E8-B48F-1D18A9856A87","first_name":"Vasu","last_name":"Singh","full_name":"Singh, Vasu"}]},{"author":[{"first_name":"Pavol","id":"4DCBEFFE-F248-11E8-B48F-1D18A9856A87","last_name":"Cerny","full_name":"Cerny, Pavol"},{"last_name":"Alur","full_name":"Alur, Rajeev","first_name":"Rajeev"}],"article_processing_charge":"No","date_published":"2009-07-01T00:00:00Z","date_updated":"2025-07-02T06:32:32Z","year":"2009","alternative_title":["LNCS"],"status":"public","publication_status":"published","date_created":"2018-12-11T12:08:36Z","abstract":[{"text":"We address the problem of analyzing programs such as J2ME midlets for mobile devices, where a central correctness requirement concerns confidentiality of data that the user wants to keep secret.

They can define quantitative languages L that assign to each word w a real number L(w). In the case of infinite words, the value of a run is naturally computed as the maximum, limsup, liminf, limit average, or discounted sum of the transition weights. We study expressiveness and closure questions about these quantitative languages. We first show that the set of words with value greater than a threshold can be non-w-regular for deterministic limit-average and discounted-sum automata, while this set is always w-regular when the threshold is isolated (i.e., some neighborhood around the threshold contains no word). In the latter case, we prove that the w-regular language is robust against small perturbations of the transition weights. We next consider automata with transition weights 0 or 1 and show that they are as expressive as general weighted automata in the limit-average case, but not in the discounted-sum case. Third, for quantitative languages L-1 and L-2, we consider the operations max(L-1, L-2), min(L-1, L-2), and 1-L-1, which generalize the boolean operations on languages, as well as the sum L-1 + L-2. We establish the closure properties of all classes of quantitative languages with respect to these four operations.","lang":"eng"}],"publication_status":"published","doi":"10.1109/LICS.2009.16","quality_controlled":"1","type":"conference","oa_version":"None","status":"public"},{"author":[{"full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu"},{"first_name":"Laurent","full_name":"Doyen, Laurent","last_name":"Doyen"},{"orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","full_name":"Henzinger, Thomas A","last_name":"Henzinger"}],"date_updated":"2024-10-09T20:53:55Z","department":[{"_id":"KrCh"}],"status":"public","doi":"10.1007/978-3-642-03409-1_2","publication_status":"published","oa_version":"Submitted Version","type":"conference","conference":{"end_date":"2009-09-04","start_date":"2009-09-02","location":"Wroclaw, Poland","name":"FCT: Fundamentals of Computation Theory"},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"09","file":[{"file_name":"IST-2012-39-v1+1_Alternating_Weighted_Automata.pdf","date_updated":"2020-07-14T12:46:31Z","relation":"main_file","checksum":"e8f53abb63579de3f2bff58b2a1188e2","file_size":164428,"file_id":"5126","access_level":"open_access","date_created":"2018-12-12T10:15:09Z","content_type":"application/pdf","creator":"system"}],"acknowledgement":"This research was supported in part by the Swiss National Science Foundation under the Indo-Swiss Joint Research Programme, by the European Network of Excellence on Embedded Systems Design (ArtistDesign), by the European Combest, Quasimodo, and Gasics projects, by the PAI program Moves funded by the Belgian Federal Government, and by the CFV (Federated Center in Verification) funded by the F.R.S.-FNRS.","page":"3 - 13","has_accepted_license":"1","citation":{"apa":"Chatterjee, K., Doyen, L., &#38; Henzinger, T.

Nondeterministic weighted automata define quantitative languages L that assign to each word w a real number L(w) computed as the maximal value of all runs over w, and the value of a run r is a function of the sequence of weights that appear along r. There are several natural functions to consider such as Sup, LimSup, LimInf, limit average, and discounted sum of transition weights.\r\nWe introduce alternating weighted automata in which the transitions of the runs are chosen by two players in a turn-based fashion. Each word is assigned the maximal value of a run that the first player can enforce regardless of the choices made by the second player. We survey the results about closure properties, expressiveness, and decision problems for nondeterministic weighted automata, and we extend these results to alternating weighted automata.\r\nFor quantitative languages L 1 and L 2, we consider the pointwise operations max(L 1,L 2), min(L 1,L 2), 1 − L 1, and the sum L 1 + L 2. We establish the closure properties of all classes of alternating weighted automata with respect to these four operations.\r\nWe next compare the expressive power of the various classes of alternating and nondeterministic weighted automata over infinite words. In particular, for limit average and discounted sum, we show that alternation brings more expressive power than nondeterminism.\r\nFinally, we present decidability results and open questions for the quantitative extension of the classical decision problems in automata theory: emptiness, universality, language inclusion, and language equivalence."}],"intvolume":"      5699","date_created":"2018-12-11T12:09:23Z","quality_controlled":"1","publist_id":"180","volume":5699,"title":"Alternating weighted automata","ec_funded":1,"ddc":["004"],"_id":"4542","day":"10","publisher":"Springer"},{"acknowledgement":"This research was supported in part by the Swiss National Science Foundation under the Indo-Swiss Joint Research Programme, by the European Network of Excellence on Embedded Systems Design (ArtistDesign), and by the European project Combest.","page":"34 - 54","month":"08","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","conference":{"end_date":"2009-08-28","name":"MFCS: Mathematical Foundations of Computer Science","start_date":"2009-08-24","location":"High Tatras, Slovakia"},"scopus_import":1,"corr_author":"1","project":[{"_id":"25EFB36C-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"COMponent-Based Embedded Systems design Techniques","grant_number":"215543"},{"grant_number":"214373","name":"Design for Embedded Systems","_id":"25F1337C-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"citation":{"chicago":"Chatterjee, Krishnendu, Thomas A Henzinger, and Florian Horn. “Stochastic Games with Finitary Objectives,” 5734:34–54.

At every round of a game, each player simultaneously and independently selects a move; the moves jointly determine the transition to a successor state. Two basic objectives are the safety objective to stay forever in a given set of states, and its dual, the reachability objective to reach a given set of states. We present in this paper a strategy improvement algorithm for computing the value of a concurrent safety game, that is, the maximal probability with which player 1 can enforce the safety objective. The algorithm yields a sequence of player-1 strategies which ensure probabilities of winning that converge monotonically to the value of the safety game. Our result is significant because the strategy improvement algorithm provides, for the first time, a way to approximate the value of a concurrent safety game from below. Since a value iteration algorithm, or a strategy improvement algorithm for reachability games, can be used to approximate the same value from above, the combination of both algorithms yields a method for computing a converging sequence of upper and lower bounds for the values of concurrent reachability and safety games. Previous methods could approximate the values of these games only from one direction, and as no rates of convergence are known, they did not provide a practical way to solve these games."}],"date_created":"2018-12-11T12:09:24Z","main_file_link":[{"url":"https://repository.ist.ac.at/id/eprint/37","open_access":"1"}],"doi":"10.1137/1.9781611973068.23","quality_controlled":0,"type":"conference","status":"public","date_published":"2009-01-01T00:00:00Z","date_updated":"2021-01-12T07:59:35Z","year":"2009","author":[{"first_name":"Krishnendu","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Krishnendu Chatterjee","last_name":"Chatterjee"},{"first_name":"Luca","full_name":"de Alfaro, Luca","last_name":"De Alfaro"},{"orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","full_name":"Thomas Henzinger","last_name":"Henzinger"}],"oa":1},{"title":"A survey of stochastic games with limsup and liminf objectives","ec_funded":1,"volume":5556,"publist_id":"177","day":"24","publisher":"Springer","_id":"4545","ddc":["000","005"],"alternative_title":["LNCS"],"year":"2009","date_published":"2009-06-24T00:00:00Z","oa":1,"quality_controlled":"1","intvolume":"      5556","date_created":"2018-12-11T12:09:24Z","abstract":[{"text":"A stochastic game is a two-player game played oil a graph, where in each state the successor is chosen either by One of the players, or according to a probability distribution.

However, among two implementations that satisfy a given specification, one may be preferred to another. For example, if a specification asks that every request is followed by a response, one may prefer an implementation that generates responses quickly but does not generate unnecessary responses. We use quantitative properties to measure the “goodness” of an implementation. Using games with corresponding quantitative objectives, we can synthesize “optimal” implementations, which are preferred among the set of possible implementations that satisfy a given specification.\r\nIn particular, we show how automata with lexicographic mean-payoff conditions can be used to express many interesting quantitative properties for reactive systems. In this framework, the synthesis of optimal implementations requires the solution of lexicographic mean-payoff games (for safety requirements), and the solution of games with both lexicographic mean-payoff and parity objectives (for liveness requirements). We present algorithms for solving both kinds of novel graph games."}],"main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/0904.2638"}],"quality_controlled":"1","date_published":"2009-06-19T00:00:00Z","year":"2009","alternative_title":["LNCS"],"oa":1,"_id":"4569","arxiv":1,"publisher":"Springer","day":"19","volume":5643,"publist_id":"141","ec_funded":1,"title":"Better quality in synthesis through quantitative objectives"},{"pubrep_id":"35","citation":{"apa":"Berwanger, D., Chatterjee, K., De Wulf, M., Doyen, L., &#38; Henzinger, T.

These simulations firstly allow verifying whether the chosen forming process conditions promote or not an optimized filling of the superficial cavities in order to achieve precise replicas which best reproduce the superficial topography of the mould. The simulations were carried out to evaluate the filling of the cavities taking into account the mechanical behaviour of the selected polymer into the model. Moreover, these models were developed to verify the effect of the distribution of the mould cavities on their filling. The influence of the mobility of non deformable rigid plates on the filling of the cavities represents an auxiliary variable. In the approach presented, the compression plates are assumed to be parallel and non deformable, whereas the polymer disk follows a rubbery behaviour around a temperature equal to 140°C. Globally the modelling results are satisfactory for they are rather close to the experimental observations conducted. In summary, the effect of the normal stress as also the distribution of micro-cavities at the mould surface seem to prevail in the case of the forming process by hot embossing."}],"intvolume":"        15","date_created":"2026-03-30T12:22:47Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"06","publication_identifier":{"issn":["0946-7076"],"eissn":["1432-1858"]},"page":"827-835","OA_type":"closed access","language":[{"iso":"eng"}],"citation":{"mla":"Sahli, Mohamed, et al. “Experimental Analysis and Numerical Modelling of the Forming Process of Polypropylene Replicas of Micro-Cavities Using Hot Embossing.” <i>Microsystem Technologies</i>, vol. 15, no. 6, Springer Nature, 2009, pp. 827–35, doi:<a href=\"https://doi.org/10.1007/s00542-009-0813-6\">10.1007/s00542-009-0813-6</a>.","short":"M.
