Research

Areas

Projects and Software

InProSSA: Integration of Symbolic and Subsymbolic AI for Industry (2025–2026)

I am the representative of the RISC institute in this project pursued together with the RISC Software company and the Institute for Symbolic AI.

The SLANG Semantics-Based Language Generator (2023–)

A software for generating rapid prototype implementations of programming languages from their formal specifications.

The RISCTP Theorem Proving Interface (2022–)

A language and associated software system for connecting formal specification systems to theorem provers.

The RISC Algorithm Language (RISCAL, 2017–)

A language and associated software system for specifying and verifying mathematical algorithms.

LOGTECHEDU: Logic Technology for Computer Science Education (2018–2020)

I am a member of this JKU LIT project on the development of novel logic techniques for computer science education.

Supercomputer MACH-2 (2017–2021)

I am the JKU representative and coordinator of this project on the collaborative use of a massively parallel shared memory supercomputer.

EU Project PRACE 4-IP (2015–2018)

In the frame of this project, RISC (institute and company) jointly engage in high-performance software development and training and dissemination activities.

LogicGuard II (2014–2016)

This is a project on the efficient checking of time-quantified logic formulas with applications in computer security.

LogicGuard (2012–2013)

This is a project on the efficient checking of time-quantified logic formulas with applications in computer security.

EU Project PRACE 3-IP (2012–2016)

In the frame of this project, RISC (institute and company) jointly engage in high-performance software development and training and dissemination activities.

The RISC ProgramExplorer (2008–)

This is an attempt towards an interactive program reasoning environment.

DK W1214 Project “Formally Specified Computer Algebra Software” (2010-)

The goal of this project is the development of a formal framework and corresponding tools for the formal specification of computer algebra software.

The ”parallel” Command (2013)

A command line tool that reads an arbitrary number of command lines and executes them by a given number of processes in parallel.

3- and 4-Wave Resonance Condition Solver

A software for the solution of Elena Kartashova’s resonance conditions for 3- and 4-wave interactions.

The RISC ProofNavigator (2005–)

This is an attempt towards an interactive proof assistant as a first component of a future environment for formal system and program reasoning.

Austrian Grid 2 Project “Distributed Supercomputing in the Grid” (2007–2009)

The goal of this project is the development of a programming interface for running distributed applications on grid infrastructures.

EU Project EGEE-II (2006–2008)

The goal of the RISC participation in this project is to port the grid version of the SEE++ software for virtual eye surgery to the EGEE-II middleware.

The RISC SlideShow

A small tool for generating HTML-based presentations from templates (developed for producing training material in this project).

MathBroker II: Brokering Distributed Mathematical Services (2005–2007)

The goal of this project is to continue and extend the results of the previous MathBroker project on brokering mathematical services in the net.

Austrian Grid Project SEE-Grid (2004–2006)

The goal of this project is the development of a grid version of the software SEE++ for virtual eye surgery.

Brokering Distributed Mathematical Services (2001–2003)

The goal of this project is the development of a framework for brokering mathematical services that are distributed among networked servers. The foundation of this framework is a language for describing the mathematical problems solved by the services.

Distributed Maple (1998–)

Distributed Maple is a system for writing parallel programs in the computer algebra system Maple based on a communication and scheduling mechanism implemented in Java.

Integrating Temporal Specifications as Runtime Assertions into Parallel Debugging Tools (2001–2002)

This project pursues the integration of formal methods with tools for the debugging of parallel message passing programs. The idea is to generate from temporal logic specifications executable assertions that can be checked in the various states of parallel program execution.

Distributed Constraint Solving for Functional Logic Programming (1997–1999)

I am the technical leader of a research project on the development of a distributed constraint solving system based on a functional logic language.

Distributed Algorithms in Java (1997)

DAJ is a toolkit for designing, implementing, testing, simulating, and visualizing distributed algorithms in Java.

High-Performance Generic Programming (1996–1998)

I direct a research project on the development of a generic compilation system based on a higher-order functor language that can be retargetted to multiple core languages.

COOPERATE (1998)

In the frame of the COOPERATE initiative, we are developing a component of a software system for the support of distributed meetings.

The RT++ Thread Package (1996)

This is a C++ package that provides higher-order threads in a type-safe framework with garbage collection.

The pD Compiler (1993–1994)

In my Ph.D. thesis I developed a compiler for a small para-functional programming language that used a new technique to generate parallelism from annotated functional programs. The target code is efficient PACLIB C code with explicit task creation and synchronization constructs.

The PACLIB Runtime Kernel (1992–1993)

Hoon Hong and I developed a parallel variant of the runtime kernel of the computer algebra library SACLIB. The parallel kernel supports on shared memory multiprocessors tasks as first order objects with garbage-collection, non-determinism, and lazy task creation.

Adam & Eve – An Abstract Dataflow Machine and Its Programming Language (1989–1990)

This was the title of my diploma thesis where I developed on a multi-transputer system a parallel simulator for a new kind of dataflow architecture,
