We consider the problem of statically scheduling a large job expressed as a task graph on a large number of computing nodes, such as a data center. This paper solves the large-scale static scheduling problem using abstraction refinement, a technique commonly used in formal verification to efficiently solve computationally hard problems. A scheduler based on abstraction refinement first attempts to solve the scheduling problem with abstract representations of the job and the computing resources. As abstract representations are generally small, the scheduling can be done reasonably fast. If the obtained schedule does not meet specified quality conditions (like data center utilization or schedule makespan) then the scheduler refines the job and data center abstractions and, again solves the scheduling problem. We develop different schedulers based on abstraction refinement. We implemented these schedulers and used them to schedule task graphs from various computing domains on simulated data centers with realistic topologies. We compared the speed of scheduling and the quality of the produced schedules with our abstraction refinement schedulers against a baseline scheduler that does not use any abstraction. We conclude that abstraction refinement techniques give a significant speed-up compared to traditional static scheduling heuristics, at a reasonable cost in the quality of the produced schedules. We further used our static schedulers in an actual system that we deployed on Amazon EC2 and compared it against the Hadoop dynamic scheduler for large MapReduce jobs. Our experiments indicate that there is great potential for static scheduling techniques.","lang":"eng"}],"citation":{"ama":"Henzinger TA, Singh V, Wies T, Zufferey D.

The goal of the approach is to allow the programmer to specify a part of her intent imperatively (that is, give a partial program) and a part of her intent declaratively, by specifying which conditions need to be achieved or maintained. The task of the synthesizer is to construct a program that satisfies the specification. As an example, consider a partial program where threads access shared data without using any synchronization mechanism, and a declarative specification that excludes data races and deadlocks. The task of the synthesizer is then to place locks into the program code in order for the program to meet the specification.\r\n\r\nIn this paper, we argue that quantitative objectives are needed in partial-program synthesis in order to produce higher-quality programs, while enabling simpler specifications. Returning to the example, the synthesizer could construct a naive solution that uses one global lock for shared data. This can be prevented either by constraining the solution space further (which is error-prone and partly defeats the point of synthesis), or by optimizing a quantitative objective that models performance. Other quantitative notions useful in synthesis include fault tolerance, robustness, resource (memory, power) consumption, and information flow.","lang":"eng"}],"citation":{"mla":"Cerny, Pavol, and Thomas A.

More precisely, the weight in the i-th position of the run is divided by lambda^i, where the discount factor lambda is a fixed rational number greater than 1. Discounted summation is a common and useful measuring scheme, especially for infinite sequences, which reflects the assumption that earlier weights are more important than later weights. Determinizing automata is often essential, for example, in formal verification, where there are polynomial algorithms for comparing two deterministic NDAs, while the equivalence problem for NDAs is not known to be decidable. Unfortunately, however, discounted-sum automata are, in general, not determinizable: it is currently known that for every rational discount factor 1 &lt; lambda &lt; 2, there is an NDA with lambda (denoted lambda-NDA) that cannot be determinized. We provide positive news, showing that every NDA with an integral factor is determinizable. We also complete the picture by proving that the integers characterize exactly the discount factors that guarantee determinizability: we show that for every non-integral rational factor lambda, there is a nondeterminizable lambda-NDA. Finally, we prove that the class of NDAs with integral discount factors enjoys closure under the algebraic operations min, max, addition, and subtraction, which is not the case for general NDAs nor for deterministic NDAs. This shows that for integral discount factors, the class of NDAs forms an attractive specification formalism in quantitative formal verification. All our results hold equally for automata over finite words and for automata over infinite words.

Information-theoretic quantitative relaxations of noninterference (based on Shannon entropy)have been introduced to enable more fine-grained reasoning about programs in situations where limited information flow is acceptable. The QIF bounding problem asks whether the information flow in a given program is bounded by a constant $d$. Our first result is that the QIF bounding problem is PSPACE-complete. The QIF memoryless synthesis problem asks whether it is possible to resolve nondeterministic choices in a given partial program in such a way that in the resulting deterministic program, the quantitative information flow is bounded by a given constant $d$. Our second result is that the QIF memoryless synthesis problem is also EXPTIME-complete. The QIF memoryless synthesis problem generalizes to QIF general synthesis problem which does not impose the memoryless requirement (that is, by allowing the synthesized program to have more variables then the original partial program). Our third result is that the QIF general synthesis problem is EXPTIME-hard.","lang":"eng"}],"project":[{"name":"Quantitative Reactive Modeling","grant_number":"267989","_id":"25EE3708-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"},{"_id":"25F5A88A-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Moderne Concurrency Paradigms","grant_number":"S11402-N23"},{"grant_number":"S 11407_N23","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"oa":1,"isi":1,"language":[{"iso":"eng"}],"month":"06","page":"205 - 217","year":"2011"},{"publication_status":"published","day":"01","intvolume":"      6901","_id":"3362","scopus_import":1,"has_accepted_license":"1","ddc":["000"],"date_created":"2018-12-11T12:02:54Z","status":"public","oa_version":"Submitted Version","type":"conference","alternative_title":["LNCS"],"conference":{"end_date":"2011-09-09","start_date":"2011-09-06","name":"CONCUR: Concurrency Theory","location":"Aachen, Germany"},"file_date_updated":"2020-07-14T12:46:10Z","quality_controlled":"1","file":[{"date_created":"2020-05-19T16:17:48Z","file_name":"2011_CONCUR_Fisher.pdf","creator":"dernst","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"7870","date_updated":"2020-07-14T12:46:10Z","file_size":337125,"checksum":"6bf2453d8e52e979ddb58d17325bad26"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1007/978-3-642-23217-6_27","citation":{"short":"J.

Such formalisms, however, have difficulty with modeling process creation or death and communication reconfigurability. Here, we introduce “dynamic reactive modules” (DRM), a state-transition modeling formalism that supports dynamic reconfiguration and creation/death of processes. The resulting formalism supports two types of variables, data variables and reference variables. Reference variables enable changing the connectivity between processes and referring to instances of processes. We show how this new formalism supports parallel composition and refinement through trace containment. DRM provide a natural language for modeling (and ultimately reasoning about) biological systems and multiple threads communicating through shared variables.","lang":"eng"}],"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik"},{"article_number":"1104.0127","citation":{"ista":"Chatterjee K, Henzinger TA, Tracol M.

The input consists of a nondeterministic partial program and of a parametric performance model. The nondeterminism allows the programmer to omit which (if any) synchronization construct is used at a particular program location. The performance model, specified as a weighted automaton, can capture system architectures by assigning different costs to actions such as locking, context switching, and memory and cache accesses. The quantitative synthesis problem is to automatically resolve the nondeterminism of the partial program so that both correctness is guaranteed and performance is optimal. As is standard for shared memory concurrency, correctness is formalized &quot;specification free&quot;, in particular as race freedom or deadlock freedom. For worst-case (average-case) performance, we show that the problem can be reduced to 2-player graph games (with probabilistic transitions) with quantitative objectives. While we show, using game-theoretic methods, that the synthesis problem is Nexp-complete, we present an algorithmic method and an implementation that works efficiently for concurrent programs and performance models of practical interest. We have implemented a prototype tool and used it to synthesize finite-state concurrent programs that exhibit different programming patterns, for several performance models representing different architectures.

The games are concurrent in that at each turn, both players independently propose a time delay and an action, and the action with the shorter delay is chosen. To prevent a player from winning by blocking time, we restrict each player to play strategies that ensure that the player cannot be responsible for causing a zeno run. First, we present an efficient reduction of these games to turn-based (i.e., not concurrent) finite-state (i.e., untimed) parity games. Our reduction improves the best known complexity for solving timed parity games. Moreover, the rich class of algorithms for classical parity games can now be applied to timed parity games. The states of the resulting game are based on clock regions of the original game, and the state space of the finite game is linear in the size of the region graph. Second, we consider two restricted classes of strategies for the player that represents the controller in a real-time synthesis problem, namely, limit-robust and bounded-robust winning strategies. Using a limit-robust winning strategy, the controller cannot choose an exact real-valued time delay but must allow for some nonzero jitter in each of its actions. If there is a given lower bound on the jitter, then the strategy is bounded-robust winning. We show that exact strategies are more powerful than limit-robust strategies, which are more powerful than bounded-robust winning strategies for any bound. For both kinds of robust strategies, we present efficient reductions to standard timed automaton games. These reductions provide algorithms for the synthesis of robust real-time controllers."}],"language":[{"iso":"eng"}],"month":"12","year":"2011","oa":1,"corr_author":"1","related_material":{"record":[{"status":"public","id":"3876","relation":"earlier_version"}]},"date_created":"2018-12-11T12:02:37Z","type":"journal_article","oa_version":"Published Version","status":"public","publication":"Logical Methods in Computer Science","_id":"3315","day":"14","intvolume":"         7","publication_status":"published","ddc":["000","005"],"has_accepted_license":"1","scopus_import":"1","doi":"10.2168/LMCS-7(4:8)2011","license":"https://creativecommons.org/licenses/by-nd/4.0/","citation":{"mla":"Chatterjee, Krishnendu, et al. “Timed Parity Games: Complexity and Robustness.” <i>Logical Methods in Computer Science</i>, vol. 7, no. 4, International Federation for Computational Logic, 2011, doi:<a href=\"https://doi.org/10.2168/LMCS-7(4:8)2011\">10.2168/LMCS-7(4:8)2011</a>.","short":"K.

We investigate the extension of temporal logics with the prefix-accumulation assertions Sum(v) ≥ c and Avg(v) ≥ c, where v is a numeric variable of the system, c is a constant rational number, and Sum(v) and Avg(v) denote the accumulated sum and average of the values of v from the beginning of the computation up to the current point of time. We also allow the path-accumulation assertions LimInfAvg(v) ≥ c and LimSupAvg(v) ≥ c, referring to the average value along an entire computation. We study the border of decidability for extensions of various temporal logics. In particular, we show that extending the fragment of CTL that has only the EX, EF, AX, and AG temporal modalities by prefix-accumulation assertions and extending LTL with path-accumulation assertions, result in temporal logics whose model-checking problem is decidable. The extended logics allow to significantly extend the currently known energy and mean-payoff objectives. Moreover, the prefix-accumulation assertions may be refined with \"controlled-accumulation\", allowing, for example, to specify constraints on the average waiting time between a request and a grant. On the negative side, we show that the fragment we point to is, in a sense, the maximal logic whose extension with prefix-accumulation assertions permits a decidable model-checking procedure. Extending a temporal logic that has the EG or EU modalities, and in particular CTL and LTL, makes the problem undecidable."}],"project":[{"call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering"},{"call_identifier":"FP7","_id":"25EFB36C-B435-11E9-9278-68D0E5697425","grant_number":"215543","name":"COMponent-Based Embedded Systems design Techniques"},{"grant_number":"267989","name":"Quantitative Reactive Modeling","_id":"25EE3708-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"},{"grant_number":"214373","name":"Design for Embedded Systems","call_identifier":"FP7","_id":"25F1337C-B435-11E9-9278-68D0E5697425"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"date_published":"2011-06-21T00:00:00Z","publist_id":"3259","author":[{"id":"31E297B6-F248-11E8-B48F-1D18A9856A87","first_name":"Udi","last_name":"Boker","full_name":"Boker, Udi"},{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee"},{"first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A"},{"last_name":"Kupferman","first_name":"Orna","full_name":"Kupferman, Orna"}],"title":"Temporal specifications with accumulative values","date_updated":"2026-07-07T14:01:43Z","article_processing_charge":"No","external_id":{"isi":["000297350400007"]},"department":[{"_id":"ToHe"},{"_id":"KrCh"}],"ec_funded":1,"file":[{"access_level":"open_access","file_name":"IST-2012-83-v1+1_Temporal_specifications_with_accumulative_values.pdf","creator":"system","date_created":"2018-12-12T10:12:42Z","checksum":"792128f5455f0f40f1105f0398e05fa9","date_updated":"2020-07-14T12:46:09Z","file_size":225426,"file_id":"4960","relation":"main_file","content_type":"application/pdf"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","file_date_updated":"2020-07-14T12:46:09Z","article_number":"5970226","citation":{"apa":"Boker, U., Chatterjee, K., Henzinger, T.

In this work we propose such a theory for synchronous concurrent systems. Our approach follows so-called interface theories, which use game-theoretic interpretations of composition and refinement. These are appropriate for systems with distinct inputs and outputs, and explicit conditions on inputs that must be enforced during composition. Our interfaces model systems that execute in an infinite sequence of synchronous rounds. At each round, a contract must be satisfied. The contract is simply a relation specifying the set of valid input/output pairs. Interfaces can be composed by parallel, serial or feedback composition. A refinement relation between interfaces is defined, and shown to have two main properties: (1) it is preserved by composition, and (2) it is equivalent to substitutability, namely, the ability to replace an interface by another one in any context. Shared refinement and abstraction operators, corresponding to greatest lower and least upper bounds with respect to refinement, are also defined. Input-complete interfaces, that impose no restrictions on inputs, and deterministic interfaces, that produce a unique output for any legal input, are discussed as special cases, and an interesting duality between the two classes is exposed. A number of illustrative examples are provided, as well as algorithms to compute compositions, check refinement, and so on, for finite-state interfaces.","lang":"eng"}],"pubrep_id":"85","publisher":"ACM","department":[{"_id":"ToHe"}],"article_processing_charge":"No","external_id":{"isi":["000292766400003"]},"issue":"4","date_updated":"2026-07-07T14:03:34Z","title":"A theory of synchronous relational interfaces","date_published":"2011-07-01T00:00:00Z","publist_id":"3263","author":[{"full_name":"Tripakis, Stavros","last_name":"Tripakis","first_name":"Stavros"},{"full_name":"Lickly, Ben","first_name":"Ben","last_name":"Lickly"},{"last_name":"Henzinger","orcid":"0000−0002−2985−7724","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A"},{"full_name":"Lee, Edward","last_name":"Lee","first_name":"Edward"}],"das_tickbox":"1","ec_funded":1,"file_date_updated":"2020-07-14T12:46:09Z","quality_controlled":"1","file":[{"content_type":"application/pdf","relation":"main_file","file_id":"5235","file_size":775662,"date_updated":"2020-07-14T12:46:09Z","checksum":"5d44a8aa81e33210649beae507602138","date_created":"2018-12-12T10:16:45Z","creator":"system","file_name":"IST-2012-85-v1+1_A_theory_of_synchronous_relational_interfaces.pdf","access_level":"open_access"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1145/1985342.1985345","citation":{"chicago":"Tripakis, Stavros, Ben Lickly, Thomas A Henzinger, and Edward Lee. “A Theory of Synchronous Relational Interfaces.” <i>ACM Transactions on Programming Languages and Systems</i>.

The games are concurrent: in each round, the two players (player 1 and player 2) choose their moves independently and simultaneously; the current state and the two moves determine the successor state. We consider ω-regular winning conditions specified as parity objectives. Both players are allowed to use randomization when choosing their moves. We study the computation of the limit-winning set of states, consisting of the states where the sup-inf value of the game for player 1 is 1: in other words, a state is limit-winning if player 1 can ensure a probability of winning arbitrarily close to 1. We show that the limit-winning set can be computed in O(n2d+2) time, where n is the size of the game structure and 2d is the number of priorities (or colors). The membership problem of whether a state belongs to the limit-winning set can be decided in NP ∩ coNP. While this complexity is the same as for the simpler class of turn-based parity games, where in each state only one of the two players has a choice of moves, our algorithms are considerably more involved than those for turn-based games. This is because concurrent games do not satisfy two of the most fundamental properties of turn-based parity games. First, in concurrent games limit-winning strategies require randomization; and second, they require infinite memory.","lang":"eng"}],"publisher":"ACM","department":[{"_id":"KrCh"},{"_id":"ToHe"}],"external_id":{"isi":["000296202300006"]},"article_processing_charge":"No","date_updated":"2026-07-07T14:02:38Z","title":"Qualitative concurrent parity games","issue":"4","author":[{"orcid":"0000-0002-4561-241X","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu"},{"first_name":"Luca","last_name":"De Alfaro","full_name":"De Alfaro, Luca"},{"full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger"}],"date_published":"2011-07-04T00:00:00Z","publist_id":"3262","das_tickbox":"1","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1145/1970398.1970404","citation":{"ieee":"K.

The system combines static analysis of programs with symbolic summation techniques to derive loop invariant relations between program variables. Iteration bounds are obtained from the inferred invariants, by replacing variables with bounds on their greatest values. We have successfully applied ABC to a large number of examples. The derived symbolic bounds express non-trivial polynomial relations over loop variables. We also report on results to automatically infer symbolic expressions over harmonic numbers as upper bounds on loop iteration counts."}],"article_processing_charge":"No","external_id":{"isi":["000309668000007"]},"department":[{"_id":"ToHe"}],"date_published":"2010-05-01T00:00:00Z","author":[{"full_name":"Blanc, Régis","first_name":"Régis","last_name":"Blanc"},{"orcid":"0000-0002-2985-7724","last_name":"Henzinger","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A"},{"last_name":"Hottelier","first_name":"Thibaud","full_name":"Hottelier, Thibaud"},{"full_name":"Kovács, Laura","last_name":"Kovács","first_name":"Laura"}],"main_file_link":[{"url":"https://infoscience.epfl.ch/record/186096","open_access":"1"}],"title":"ABC: Algebraic Bound Computation for loops","series_title":"LNCS","date_updated":"2025-09-30T09:51:13Z","place":"Berlin, Heidelberg"},{"has_accepted_license":"1","editor":[{"first_name":"Luke","last_name":"Ong","full_name":"Ong, Luke"}],"ddc":["004"],"scopus_import":1,"_id":"4361","publication_status":"published","day":"01","intvolume":"      6014","alternative_title":["LNCS"],"type":"conference","conference":{"start_date":"2010-03-20","name":"FoSSaCS: Foundations of Software Science and Computation Structures","location":"Paphos, Cyprus","end_date":"2010-03-28"},"status":"public","oa_version":"Submitted Version","corr_author":"1","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"1405"}]},"date_created":"2018-12-11T12:08:27Z","file":[{"access_level":"open_access","date_created":"2018-12-12T10:08:17Z","creator":"system","file_name":"IST-2012-50-v1+1_Forward_analysis_of_depth-bounded_processes.pdf","file_size":240766,"date_updated":"2020-07-14T12:46:27Z","checksum":"3e610de84937d821316362658239134a","content_type":"application/pdf","relation":"main_file","file_id":"4677"}],"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","file_date_updated":"2020-07-14T12:46:27Z","citation":{"mla":"Wies, Thomas, et al. <i>Forward Analysis of Depth-Bounded Processes</i>.

In this paper we develop an adequate domain of limits for the well-structured transition systems that are induced by depth-bounded processes. An immediate consequence of our result is that there exists a forward algorithm that decides the covering problem for this class. Unlike backward algorithms, the forward algorithm terminates even if the depth of the process is not known a priori. More importantly, our result suggests a whole spectrum of forward algorithms that enable the effective verification of a large class of mobile systems."}]},{"doi":"10.1007/978-3-642-16612-9_32","publisher":"Springer","volume":6418,"citation":{"chicago":"Singh, Vasu. “Runtime Verification for Software Transactional Memories.” edited by Oleg Sokolsky, Grigore Rosu, Nikolai Tilmann, Howard Barringer, Ylies Falcone, Bernd Finkbeiner, Klaus Havelund, Insup Lee, and Gordon Pace, 6418:421–35.

Several correctness properties have been proposed for STMs. Based on a bounded conflict graph algorithm for verifying correctness of STMs, we develop TRACER, a tool for runtime verification of STM implementations. The novelty of TRACER lies in the way it combines coarse and precise runtime analyses to guarantee sound and complete verification in an efficient manner. We implement TRACER in the TL2 STM implementation. We evaluate the performance of TRACER on STAMP benchmarks. While a precise runtime verification technique based on conflict graphs results in an average slowdown of 60x, the two-level approach of TRACER performs complete verification with an average slowdown of around 25x across different benchmarks."}],"language":[{"iso":"eng"}],"quality_controlled":"1","page":"421 - 435","year":"2010","month":"01","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","corr_author":"1","date_created":"2018-12-11T12:08:28Z","type":"conference","alternative_title":["LNCS"],"conference":{"end_date":"2010-11-04","location":"St. Julians, Malta","start_date":"2010-11-01","name":"RV: International Conference on Runtime Verification"},"oa_version":"None","status":"public","_id":"4362","publication_status":"published","day":"01","department":[{"_id":"ToHe"}],"intvolume":"      6418","publist_id":"1096","date_published":"2010-01-01T00:00:00Z","editor":[{"full_name":"Sokolsky, Oleg","last_name":"Sokolsky","first_name":"Oleg"},{"last_name":"Rosu","first_name":"Grigore","full_name":"Rosu, Grigore"},{"full_name":"Tilmann, Nikolai","first_name":"Nikolai","last_name":"Tilmann"},{"full_name":"Barringer, Howard","last_name":"Barringer","first_name":"Howard"},{"last_name":"Falcone","first_name":"Ylies","full_name":"Falcone, Ylies"},{"first_name":"Bernd","last_name":"Finkbeiner","full_name":"Finkbeiner, Bernd"},{"full_name":"Havelund, Klaus","last_name":"Havelund","first_name":"Klaus"},{"full_name":"Lee, Insup","first_name":"Insup","last_name":"Lee"},{"first_name":"Gordon","last_name":"Pace","full_name":"Pace, Gordon"}],"author":[{"last_name":"Singh","first_name":"Vasu","id":"4DAE2708-F248-11E8-B48F-1D18A9856A87","full_name":"Singh, Vasu"}],"title":"Runtime verification for software transactional memories","scopus_import":1,"date_updated":"2024-10-09T20:54:01Z"}]
