My current research interests include: high performance data analytics, modeling and optimization, software performance engineering, and parallel computing.
I also enjoy studying the properties of various kinds of systems (such as parallel computers, flexible manufacturing systems or health-care systems) using innovative modeling and simulation techniques.
In my parallel computing lab at LNU we use for research DISA that comprises 19 DELL EMC nodes (14 PowerEdge R740 and 5 PowerEdge R740XD); heterogeneous nodes of DISA contain two 20-core CPUs (Intel Xeon Gold 6148) and four NVIDIA GPUs.

HiPro: high-level programming of multi-core computing systems.
HiPro aims to develop a high-level program development model for
multi-core computing systems, which hides the complex details of
low-level multi-threading. Our approach supports a compositional
program development process, where programs are constructed from
smaller parallel building blocks that are adapted and tuned for a
specific multi-core platform.
Responsibilities: high-level programming of multi-core computing systems.
Contributions: an intelligent compositional program development approach for multi-core computing systems.

a holistic service-oriented environment for
QoS-aware Grid workflows. Amadeus considers user
requirements (in form of QoS constraints) during workflow
specification, planning, and execution. A distinguishing feature of
Amadeus is the support of a comprehensive set of QoS requirements,
that consider in addition to performance and economical aspects also
legal and security aspects. Amadeus project introduced the concept
of Location Affinity, which allows the user to express preferences
regarding the location of Grid resources where an activity should be
executed, by specifying the Grid site, organizational, or

Aurora: Advanced Models, Applications and Software Systems for High Performance Computing.
A special research program (SFB) funded by the Austrian Science Fund (FWF), 1997--2007.
The special research program Aurora was a distinctively interdisciplinary project, based
upon a highly synergetic cooperation of the participating
institutions across a broad range of disciplines that include:
parallel languages, compilers, runtime systems, performance
evaluation tools, numerical algorithms, computational finance,
theoretical chemistry, and atto-second physics.
Responsibilities: performance modeling and prediction.
Contributions: development of an approach and the corresponding tool-support for the performance modeling and prediction of parallel and distributed computing systems.
a performance modeling and prediction system for
parallel and distributed programs. Our approach supports the
graphical specification of performance model in a human-intuitive
fashion on one hand, and on the other hand is amenable to
machine-efficient model evaluation. The model transformation, from
the graphical human-intuitive form (that is, UML representation), to
the form that can be efficiently evaluated by a machine (that is, C++
representation), is performed automatically. Our methodology for
performance prediction of computing systems combines mathematical
modeling and simulation. We use mathematical modeling to develop
parameterized performance models (that is, cost functions) for
components of the system. Thereafter, we use discrete-event
simulation to describe the structure of system. The aim is to combine the model evaluation
efficiency of mathematical performance models with the structure
awareness of simulation models.

Contributions: design and implementation of Performance Prophet.
a platform-independent and extensible graphical editor for the UML-based
modeling of parallel and distributed programs. The main
components of Teuta are: Model Checker, Model Traverser, and the
Graphical User Interface (GUI). The GUI of Teuta is used for the
development of UML model. The Model Checker is used to verify
whether the model conforms to the UML specification. For the
generation of different model representations (such as XML or C++)
the Model Traverser is used.
Responsibilities: principal investigator.
Contributions: design and implementation of Teuta.
