The Scalasca performance toolset architecture

M Geimer, F Wolf, BJN Wylie… - Concurrency and …, 2010 - Wiley Online Library
Scalasca is a performance toolset that has been specifically designed to analyze parallel
application execution behavior on large‐scale systems with many thousands of processors. It …

SMT-RAT: An Open Source C++ Toolbox for Strategic and Parallel SMT Solving

F Corzilius, G Kremer, S Junges, S Schupp… - Theory and Applications …, 2015 - Springer
During the last decade, popular SMT solvers have been extended step-by-step with a wide
range of decision procedures for different theories. Some SMT solvers also support the user-…

Flow*: An analyzer for non-linear hybrid systems

X Chen, E Ábrahám, S Sankaranarayanan - Computer Aided Verification …, 2013 - Springer
The tool Flow* performs Taylor model-based flowpipe construction for non-linear (polynomial)
hybrid systems. Flow* combines well-known Taylor model arithmetic techniques for …

Taylor model flowpipe construction for non-linear hybrid systems

X Chen, E Abraham… - 2012 IEEE 33rd Real …, 2012 - ieeexplore.ieee.org
We propose an approach for verifying non-linear hybrid systems using higher-order Taylor
models that are a combination of bounded degree polynomials over the initial conditions and …

PROPhESY: A PRObabilistic ParamEter SYnthesis Tool

C Dehnert, S Junges, N Jansen, F Corzilius… - … Aided Verification: 27th …, 2015 - Springer
We present PROPhESY, a tool for analyzing parametric Markov chains (MCs). It can
compute a rational function (ie, a fraction of two polynomials in the model parameters) for …

HyPro: A C++ Library of State Set Representations for Hybrid Systems Reachability Analysis

S Schupp, E Ábrahám, IB Makhlouf… - NASA Formal Methods …, 2017 - Springer
In this tool paper we introduce HyPro, our free and open-source C++ programming library,
which offers implementations for the most prominent state set representations used by …

Accelerating parametric probabilistic verification

N Jansen, F Corzilius, M Volk, R Wimmer… - … Evaluation of Systems, 2014 - Springer
We present a novel method for computing reachability probabilities of parametric discrete-time
Markov chains whose transition probabilities are fractions of polynomials over a set of …

Under-approximate flowpipes for non-linear continuous systems

XC Rwth, S Sankaranarayanan… - 2014 Formal Methods …, 2014 - ieeexplore.ieee.org
We propose an approach for computing under- as well as over-approximations for the
reachable sets of continuous systems which are defined by non-linear Ordinary Differential …

[HTML][HTML] Deciding the consistency of non-linear real arithmetic constraints with a conflict driven search using cylindrical algebraic coverings

E Ábrahám, JH Davenport, M England… - Journal of Logical and …, 2021 - Elsevier
We present a new algorithm for determining the satisfiability of conjunctions of non-linear
polynomial constraints over the reals, which can be used as a theory solver for satisfiability …

Prevention of influenza and pneumococcal pneumonia in Canadian long-term care facilities: how are we doing?

CG Stevenson, MA McArthur, M Naus, E Abraham… - Cmaj, 2001 - Can Med Assoc
Background: Influenza and pneumococcal pneumonia are serious health problems among
elderly people and a major cause of death in long-term care facilities. We describe the results …
