RoboCup – World Modeling

Responsible: Martin Richter

Since 1997 the RoboCup (Robot Soccer World Cup) is held, where different teams of researchers and students are competing in numerous leagues. A game of robot soccer is always played between two equally sized sets of robots, ranging from five to eleven robots per team. Depending on the league, the game is either simulated or conducted physically with real robots.If the game is played physically, multiple mobile robots perceive their environment through sensors (e.g., recognizing enemy player positions) and influence it through actuators (e.g., kicking the ball), a team of robots is classified as a mobile cyber-physical system. Achieving a consistent view of the environment in cyber-physical systems is of paramount importance, to allow the different execution units to collaborate and tackle common tasks.As a RoboCup team has to decide on which moves to take, the state of the game (e.g., player positions) has to be evaluated continuously. For this, a virtual representation of the real world is required and data has to be exchanged between the robots. Your task will be to review different models, which are concerned with the virtual representation of the real world in the RoboCup.

FMSolvr is a library for HPC molecular dynamics simulations. Currently, the team of the Supercomputing Center in Jülich, Germany, in cooperation with us is maintaining and extending their code base. In the process a performance analysis shall be conducted. Your task would be implementing and running performance tests for different implementations of the same functionality. Required knowledge: being able to read code written with C++11 or higher.

Test Development for HPC Simulation Software

Responsible:

FMSolvr is a library for HPC molecular dynamics simulations. Currently, the team of the Supercomputing Center in Jülich, Germany, in cooperation with us is maintaining and extending their code base. For new features, tests are developed together with the simulation code. However, for the existing code, tests need to be written. Your task would be to develop (and implement) tests for operators (funtional parts of the software) and/or data structures used in FMSolvr. Required knowledge: C++11 or higher.

Isabelle / HOL

Responsible: Matthias Werner

The Isabelle/HOL tool is one of the internationally leading tools for proving correctness of computer systems (theorem prover). E.g., the correctness proof of the seL4 kernel was done by the use of Isabelle. For this seminar topic, the student should give a introduction to Isabelle/HOL and the foundation behind, as well as demonstrate its practical usage by verifying a given protocol.

Python Runtime on the Base of Forth

Responsible: Matthias Werner

Forth is a syntax-less, very machine-oriented programming language with a bare-metal run-time system (i.e. without OS). The task is to develop an interpreter for Python byte code on top of a Forth system on a embedded board.

Tooling for CSP and Pi-Calculus

Responsible:

Goal of this work is to gather tooling for the formal modelling with CSP (Communicating Sequential Processes) and/or the formal verification with Pi-calculus and to evaluate their advantages and disadvantages. Solid knowledge on CSP and Pi-calculus are neither required nor subject of this work; it is a pure research work about the tooling.

Coordination Models and Languages

Responsible: Martin Richter

Coordination languages allow the programmer to describe concurrent and distributed computations through the concept of "coordination".It allows to integrate many possibly heterogeneous components by providing distribution transparency.The set of all components forms a single application in a way, that it can be executed in a distributed and parallel fashion. Papadopoulos and Arbab give an overview of different coordination languages in "Coordination Models and Languages".It will be your task to review the paper and present the different coordination models and languages, what differentiates them, what their benefits and drawbacks are and to present at least one use-case per paradigm.

Responsible: Martin Richter

Since 1997 the RoboCup (Robot Soccer World Cup) is held, where different teams of researchers and students are competing in numerous leagues. A game of robot soccer is always played between two equally sized sets of robots, ranging from five to eleven robots per team. Depending on the league, the game is either simulated or conducted physically with real robots.If the game is played physically, multiple mobile robots perceive their environment through sensors (e.g., recognizing enemy player positions) and influence it through actuators (e.g., kicking the ball), a team of robots is classified as a mobile cyber-physical system. Coordination is one of the main challenges for cyber-physical systems, as multiple heterogeneous execution units might have to cooperate to reach a common goal. To ensure a safe and timely operation, the planning of which units fulfill which tasks at which point in time is critical.As a RoboCup team has to be coordinated to conduct complex moves, coordination models are employed. Such models encompass the choice of varying tasks for different robots to reach a common main-goal or possibly multiple sub-goals. Your task will be to review different coordination models, used in the RoboCup.

Framework for Simulation and Performance Analysis of Clock Synchronization Algorithms

Responsible: Jafar Akhundov

The task is to create a framework for simulation and performance analysis of diverse clock synchronization algorithms. Implementation language/tool is irrelevant. To achieve this distributed systems must be parametrized with respect to clock synchronization. As a basis an existing master thesis can be used. The context and big goal of the work is to automatically generate synchronization modules for parametrized spacecraft systems.

Umsetzung von Programmierparadigmen der Objektorientierung zur Realisierung von Function-as-a-Service Systemen mit Microservices

Responsible: Marcus Hilbrich

Micro Services lag abstraction methods. E.g, In case multiple services are needed to process a single transaction, the concept of the transaction is not really present in the code of the services. In a first step a tool was created and evaluated to allow to write the transaction as an object oriented like class and generate services based on the methods of the class. This is not yet a general solution and needs extensions. 1) using a more general programming language (e.G. Java) 2) support additional OO concepts (generalization, polymorphy, …) 3) stronger evaluation 4) multi language support 5) multi Cloud support

Responsible: Laura Morgenstern

Research objective is the development and performance analysis of an OpenACC-based Fast Multipole Method (FMM) for the computation of electrostatical interactions in moleculardynamic simulations. The project is based on FMSolvr, a parallel C++ implementation of an FMM. Subsequently, the developed OpenACC-version of FMSolvr shall be analyzed with regard to potential performance optimizations. Furthermore, diverse parallelization strategies and parameter sets could be developed and compared against each other.
