text: "Separation logic (SL) has gained widespread popularity because of its ability
to succinctly express complex invariants of a program’s heap configurations. Several
specialized provers have been developed for decidable SL fragments. However, these
provers cannot be easily extended or combined with solvers for other theories
that are important in program verification, e.g., linear arithmetic. In this paper,
we present a reduction of decidable SL fragments to a decidable first-order theory
that fits well into the satisfiability modulo theories (SMT) framework. We show
how to use this reduction to automate satisfiability, entailment, frame inference,
and abduction problems for separation logic using SMT solvers. Our approach provides
a simple method of integrating separation logic into existing verification tools
that provide SMT backends, and an elegant way of combining SL fragments with other
decidable first-order theories. We implemented this approach in a verification
tool and applied it to heap-manipulating programs whose verification involves
reasoning in theory combinations.\r\n"

text: Depth-Bounded Systems form an expressive class of well-structured transition
systems. They can model a wide range of concurrent infinite-state systems including
those with dynamic thread creation, dynamically changing communication topology,
and complex shared heap structures. We present the first method to automatically
prove fair termination of depth-bounded systems. Our method uses a numerical abstraction
of the system, which we obtain by systematically augmenting an over-approximation
of the system’s reachable states with a finite set of counters. This numerical
abstraction can be analyzed with existing termination provers. What makes our
approach unique is the way in which it exploits the well-structuredness of the
analyzed system. We have implemented our work in a prototype tool and used it
to automatically prove liveness properties of complex concurrent systems, including
nonblocking algorithms such as Treiber’s stack and several distributed processes.
Many of these examples are beyond the scope of termination analyses that are based
on traditional counter abstractions.

text: Many infinite state systems can be seen as well-structured transition systems
(WSTS), i.e., systems equipped with a well-quasi-ordering on states that is also
a simulation relation. WSTS are an attractive target for formal analysis because
there exist generic algorithms that decide interesting verification problems for
this class. Among the most popular algorithms are acceleration-based forward analyses
for computing the covering set. Termination of these algorithms can only be guaranteed
for flattable WSTS. Yet, many WSTS of practical interest are not flattable and
the question whether any given WSTS is flattable is itself undecidable. We therefore
propose an analysis that computes the covering set and captures the essence of
acceleration-based algorithms, but sacrifices precision for guaranteed termination.
Our analysis is an abstract interpretation whose abstract domain builds on the
ideal completion of the well-quasi-ordered state space, and a widening operator
that mimics acceleration and controls the loss of precision of the analysis. We
present instances of our framework for various classes of WSTS. Our experience
with a prototype implementation indicates that, despite the inherent precision
loss, our analysis often computes the precise covering set of the analyzed system.

text: Cloud computing aims to give users virtually unlimited pay-per-use computing
resources without the burden of managing the underlying infrastructure. We present
a new job execution environment Flextic that exploits scal- able static scheduling
techniques to provide the user with a flexible pricing model, such as a tradeoff
between dif- ferent degrees of execution speed and execution price, and at the
same time, reduce scheduling overhead for the cloud provider. We have evaluated
a prototype of Flextic on Amazon EC2 and compared it against Hadoop. For various
data parallel jobs from machine learning, im- age processing, and gene sequencing
that we considered, Flextic has low scheduling overhead and reduces job du- ration
by up to 15% compared to Hadoop, a dynamic cloud scheduler.

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: 'Automated termination provers often use the following schema to prove that
a program terminates: construct a relational abstraction of the program''s transition
relation and then show that the relational abstraction is well-founded. The focus
of current tools has been on developing sophisticated techniques for constructing
the abstractions while relying on known decidable logics (such as linear arithmetic)
to express them. We believe we can significantly increase the class of programs
that are amenable to automated termination proofs by identifying more expressive
decidable logics for reasoning about well-founded relations. We therefore present
a new decision procedure for reasoning about multiset orderings, which are among
the most powerful orderings used to prove termination. We show that, using our

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: 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: Any programming error that can be revealed before compiling a program saves
precious time for the programmer. While integrated development environments already
do a good job by detecting, e.g., data-flow abnormalities, current static analysis
tools suffer from false positives ("noise") or require strong user interaction.
We propose to avoid this deficiency by defining a new class of errors. A program
fragment is doomed if its execution will inevitably fail, regardless of which
state it is started in. We use a formal verification method to identify such errors
fully automatically and, most significantly, without producing noise. We report
on experiments with a prototype tool.

text: Depth-bounded processes form the most expressive known fragment of the π-calculus
for which interesting verification problems are still decidable. 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.

text: 'Techniques such as verification condition generation, predicate abstraction,
and expressive type systems reduce software verification to proving formulas in
expressive logics. Programs and their specifications often make use of data structures
such as sets, multisets, algebraic data types, or graphs. Consequently, formulas
generated from verification also involve such data structures. To automate the
proofs of such formulas we propose a logic (a “calculus”) of such data structures.
We build the calculus by starting from decidable logics of individual data structures,
and connecting them through functions and sets, in ways that go beyond the frameworks
such as Nelson-Oppen. The result are new decidable logics that can simultaneously
specify properties of different kinds of data structures and overcome the limitations
of the individual logics. Several of our decidable logics include abstraction
functions that map a data structure into its more abstract view (a tree into a
multiset, a multiset into a set), into a numerical quantity (the size or the height),
or into the truth value of a candidate data structure invariant (sortedness, or
the heap property). For algebraic data types, we identify an asymptotic many-to-one
condition on the abstraction function that guarantees the existence of a decision
procedure. In addition to the combination based on abstraction functions, we can
combine multiple data structure theories if they all reduce to the same data structure
logic. As an instance of this approach, we describe a decidable logic whose formulas
are propositional combinations of formulas in: weak monadic second-order logic
of two successors, two-variable logic with counting, multiset algebra with Presburger
arithmetic, the Bernays-Schönfinkel-Ramsey class of first-order logic, and the
logic of algebraic data types with the set content function. The subformulas in
this combination can share common variables that refer to sets of objects along
with the common set algebra operations. Such sound and complete combination is
possible because the relations on sets definable in the component logics are all
expressible in Boolean Algebra with Presburger Arithmetic. Presburger arithmetic
and its new extensions play an important role in our decidability results. In
several cases, when we combine logics that belong to NP, we can prove the satisfiability
for the combined logic is still in NP.'

text: Cloud computing is an emerging paradigm aimed to offer users pay-per-use computing
resources, while leaving the burden of managing the computing infrastructure to
the cloud provider. We present a new programming and pricing model that gives
the cloud user the flexibility of trading execution speed and price on a per-job
basis. We discuss the scheduling and resource management challenges for the cloud
provider that arise in the implementation of this model. We argue that techniques
from real-time and embedded software can be useful in this context.

abstract:

text: Cloud computing aims to give users virtually unlimited pay-per-use computing
resources without the burden of managing the underlying infrastructure. We claim
that, in order to realize the full potential of cloud computing, the user must
be presented with a pricing model that offers flexibility at the requirements
level, such as a choice between different degrees of execution speed and the cloud
provider must be presented with a programming model that offers flexibility at
the execution level, such as a choice between different scheduling policies. In
such a flexible framework, with each job, the user purchases a virtual computer
with the desired speed and cost characteristics, and the cloud provider can optimize
the utilization of resources across a stream of jobs from different users. We
designed a flexible framework to test our hypothesis, which is called FlexPRICE
(Flexible Provisioning of Resources in a Cloud Environment) and works as follows.
A user presents a job to the cloud. The cloud finds different schedules to execute
the job and presents a set of quotes to the user in terms of price and duration
for the execution. The user then chooses a particular quote and the cloud is obliged
to execute the job according to the chosen quote. FlexPRICE thus hides the complexity
of the actual scheduling decisions from the user, but still provides enough flexibility
to meet the users actual demands. We implemented FlexPRICE in a simulator called
PRICES that allows us to experiment with our framework. We observe that FlexPRICE
provides a wide range of execution options-from fast and expensive to slow and
cheap-- for the whole spectrum of data-intensive and computation-intensive jobs.
We also observe that the set of quotes computed by FlexPRICE do not vary as the
number of simultaneous jobs increases.

that express heap assumptions (i.e., assertions describing reachability, aliasing,
separation and sharing in the heap). We present an algorithm for the inference
of such preconditions. The algorithm exploits a unique interplay between counterexample-producing
abstract termination checker and shape analysis. The shape analysis produces heap
assumptions on demand to eliminate counterexamples, i.e., non-terminating abstract
computations. The experiments with our prototype implementation indicate its practical
potential.
