text: 'Weighted automata map input words to numerical values. Ap- plications of
weighted automata include formal verification of quantitative properties, as well
as text, speech, and image processing. A weighted au- tomaton is defined with
respect to a semiring. For the tropical semiring, the weight of a run is the sum
of the weights of the transitions taken along the run, and the value of a word
is the minimal weight of an accepting run on it. In the 90’s, Krob studied the
decidability of problems on rational series defined with respect to the tropical
semiring. Rational series are strongly related to weighted automata, and Krob’s
results apply to them. In par- ticular, it follows from Krob’s results that the
universality problem (that is, deciding whether the values of all words are below
some threshold) is decidable for weighted automata defined with respect to the
tropical semir- ing with domain ∪ {∞}, and that the equality problem is undecidable
when the domain is ∪ {∞}. In this paper we continue the study of the borders of
decidability in weighted automata, describe alternative and direct proofs of the
above results, and tighten them further. Unlike the proofs of Krob, which are
algebraic in their nature, our proofs stay in the terrain of state machines, and
the reduction is from the halting problem of a two-counter machine. This enables
us to significantly simplify Krob’s reasoning, make the un- decidability result
accessible to the automata-theoretic community, and strengthen it to apply already
to a very simple class of automata: all the states are accepting, there are no
initial nor final weights, and all the weights on the transitions are from the
set {−1, 0, 1}. The fact we work directly with the automata enables us to tighten
also the decidability re- sults and to show that the universality problem for
weighted automata defined with respect to the tropical semiring with domain ∪
{∞}, and in fact even with domain ≥0 ∪ {∞}, is PSPACE-complete. Our results thus
draw a sharper picture about the decidability of decision problems for weighted
automata, in both the front of containment vs. universality and the front of the
∪ {∞} vs. the ∪ {∞} domains.'

text: Software transactional memories (STM) are described in the literature with
assumptions of sequentially consistent program execution and atomicity of high
level operations like read, write, and abort. However, in a realistic setting,
processors use relaxed memory models to optimize hardware performance. Moreover,
the atomicity of operations depends on the underlying 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 describe RML, a
simple language for expressing concurrent programs. We develop a semantics of
RML parametrized by a relaxed memory model. We then present our tool, FOIL, which
takes as input the RML description of an STM algorithm restricted to two threads
and two variables, and the description of a memory model, and automatically determines
the locations of fences, which if inserted, ensure the correctness of the restricted
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 for two threads and two variables.
Finally, we extend the verification results for DSTM and TL2 to an arbitrary number
of threads and variables by manually proving that the structural properties of
STMs are satisfied at the hardware level of atomicity under the considered relaxed
memory models.

text: We present a new decidable logic called TREX for expressing constraints about
imperative tree data structures. In particular, TREX supports a transitive closure
operator that can express reachability constraints, which often appear in data
structure invariants. We show that our logic is closed under weakest precondition
computation, which enables its use for automated software verification. We further
show that satisfiability of formulas in TREX is decidable in NP. The low complexity
makes it an attractive alternative to more expensive logics such as monadic second-order
logic (MSOL) over trees, which have been traditionally used for reasoning about
tree data structures.

text: There is recently a significant effort to add quantitative objectives to formal
verification and synthesis. We introduce and investigate the extension of temporal
logics with quantitative atomic assertions, aiming for a general and flexible
framework for quantitative-oriented specifications. In the heart of quantitative
objectives lies the accumulation of values along a computation. It is either the
accumulated summation, as with the energy objectives, or the accumulated average,
as with the mean-payoff objectives. 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.

text: 'Compositional theories are crucial when designing large and complex systems
from smaller components. 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.'

text: 'We consider two-player games played on a finite state space for an infinite
number of rounds. 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.'

text: Byzantine Fault Tolerant (BFT) protocols aim to improve the reliability of
distributed systems. They enable systems to tolerate arbitrary failures in a bounded
number of nodes. BFT protocols are usually proven correct for certain safety and
liveness properties. However, recent studies have shown that the performance of
state-of-the-art BFT protocols decreases drastically in the presence of even a
single malicious node. This motivates a formal quantitative analysis of BFT protocols
to investigate their performance characteristics under different scenarios. We
present HyPerf, a new hybrid methodology based on model checking and simulation
techniques for evaluating the performance of BFT protocols. We build a transition
system corresponding to a BFT protocol and systematically explore the set of behaviors
allowed by the protocol. We associate certain timing information with different
operations in the protocol, like cryptographic operations and message transmission.
After an elaborate state exploration, we use the time information to evaluate
the performance characteristics of the protocol using simulation techniques. We
integrate our framework in Mace, a tool for building and verifying distributed
systems. We evaluate the performance of PBFT using our framework. We describe
two different use-cases of our methodology. For the benign operation of the protocol,
we use the time information as random variables to compute the probability distribution
of the execution times. In the presence of faults, we estimate the worst-case
performance of the protocol for various attacks that can be employed by malicious
nodes. Our results show the importance of hybrid techniques in systematically
analyzing the performance of large-scale systems.

text: There is recently a significant effort to add quantitative objectives to formal
verification and synthesis. We introduce and investigate the extension of temporal
logics with quantitative atomic assertions, aiming for a general and flexible
framework for quantitative-oriented specifications. In the heart of quantitative
objectives lies the accumulation of values along a computation. It is either the
accumulated summation, as with the energy objectives, or the accumulated average,
as with the mean-payoff objectives. 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.

text: We consider two-player graph games whose objectives are request-response condition,
i.e conjunctions of conditions of the form "if a state with property Rq is visited,
then later a state with property Rp is visited". The winner of such games can
be decided in EXPTIME and the problem is known to be NP-hard. In this paper, we
close this gap by showing that this problem is, in fact, EXPTIME-complete. We
show that the problem becomes PSPACE-complete if we only consider games played
on DAGs, and NP-complete or PTIME-complete if there is only one player (depending
on whether he wants to enforce or spoil the request-response condition). We also
present near-optimal bounds on the memory needed to design winning strategies
for each player, in each case.

text: The static scheduling problem often arises as a fundamental problem in real-time
systems and grid computing. 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.

text: "Motivated by improvements in constraint-solving technology and by the increase
of routinely available computational power, partial-program synthesis is emerging
as an effective approach for increasing programmer productivity. 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."

text: 'A discounted-sum automaton (NDA) is a nondeterministic finite automaton with
edge weights, which values a run by the discounted sum of visited edge weights.
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 < lambda < 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. '

text: In this paper, we investigate the computational complexity of quantitative
information flow (QIF) problems. 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.

text: State-transition systems communicating by shared variables have been the underlying
model of choice for applications of model checking. 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.

text: Molecular noise, which arises from the randomness of the discrete events in
the cell, significantly influences fundamental biological processes. Discrete-state
continuous-time stochastic models (CTMC) can be used to describe such effects,
but the calculation of the probabilities of certain events is computationally
expensive. We present a comparison of two analysis approaches for CTMC. On one
hand, we estimate the probabilities of interest using repeated Gillespie simulation
and determine the statistical accuracy that we obtain. On the other hand, we apply
a numerical reachability analysis that approximates the probability distributions
of the system at several time instances. We use examples of cellular processes
to demonstrate the superiority of the reachability analysis if accurate results
are required.

text: We present the tool Quasy, a quantitative synthesis tool. Quasy takes qualitative
and quantitative specifications and automatically constructs a system that satisfies
the qualitative specification and optimizes the quantitative specification, if
such a system exists. The user can choose between a system that satisfies and
optimizes the specifications (a) under all possible environment behaviors or (b)
under the most-likely environment behaviors given as a probability distribution
on the possible input sequences. Quasy solves these two quantitative synthesis
problems by reduction to instances of 2-player games and Markov Decision Processes
(MDPs) with quantitative winning objectives. Quasy can also be seen as a game
solver for quantitative games. Most notable, it can solve lexicographic mean-payoff
games with 2 players, MDPs with mean-payoff objectives, and ergodic MDPs with
mean-payoff parity objectives.

text: 'We present an algorithmic method for the quantitative, performance-aware
synthesis of concurrent programs. 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 "specification free",
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. '

text: In this survey, we compare several languages for specifying Markovian population
models such as queuing networks and chemical reaction networks. All these languages
— matrix descriptions, stochastic Petri nets, stoichiometric equations, stochastic
process algebras, and guarded command models — describe continuous-time Markov
chains, but they differ according to important properties, such as compositionality,
expressiveness and succinctness, executability, and ease of use. Moreover, they
provide different support for checking the well-formedness of a model and for
analyzing a model.
