Details for the theses

Title Fluid particle simulation using SYCL
Student Markus Wippler
Language English
Supervisors Peter Thoman
Description This thesis involves the implementation of a GPU-based fluid particle simulation using SYCL, as well as its visualization.
  • Investigate possibilities for SYCL integration with graphics APIs, make an implementation choice and reason about it
  • Investigate data structures proposed in the literature for this task, perform a comparative evaluation, and choose one for your implementation
  • Implement the particle simulation using SYCL, as well as a visualization
  • Evaluate its performance across at least 2 GPU architectures
  • Implement and evaluate the impact of at least 2 optimization strategies

Title Performancevergleich zwischen PHP5 und PHP7, SQL und NoSQL, und verteilten und nicht verteilten Systemen am Beispiel einer Projektmanagament Plattform 
Student Tobias Rieser und David Abfalterer
Language English/German
Supervisors Simon Ostermann
Description Durch unsere Erfahrung bei der Implementierung einer Projektmanagement Plattform, ergeben sich aus Performancesicht mehrere Möglichkeiten der Implementierung bzw. Datenverwaltung. Einige dieser Möglichkeiten wollen wir in unserer Arbeit beleuchten.
  1. Verteiltes und nicht verteiltes Serversystem
    • Theoretischer Vergleich zwischen lokalen und verteilten Systemen
    • Performancevergleich zwischen lokalen Servern und verteilten Servern am Beispiel AWS EC2 Instanzen (1 Instanz / mehrere Instanzen / mehrere Instanzen verteilt auf mehreren Kontinenten) (Tobias Rieser)
  2.  Implementierung durch PHP5 und PHP7
    • Theoretischer Vergleich zwischen den zwei Versionen der Programmiersprache PHP (Syntax, OOP, Funktionen etc.)
    • praktischer Performancevergleich zwischen PHP5 und PHP7 auf den verschiedensten Systemen von Punkt 1
    • Untersuchung der Nutzung von JavaScript Webworker zur pseudoparallen Ausführung von Anfragen (David Abfalterer)
  3.  SQL und NoSQL Datenbanken
    • Theoretischer Vergleich zwischen SQL und NoSQL
    • Performancevergleich von SQL (MySQL) und NoSQL (AWS DynamoDB) auf den verschiedenen Systemen aus Punkt 1 und den verschiedenen Implementierungsmöglichkeiten aus Punkt 2 (Tobias Rieser und David Abfalterer)
Theoretical skills Concurrent systems
Practical skills Web 2.0, Amazon EC2, DynamoDB, MySQL
Title OpenGL Test Applications for GPU Energy and Power Consumptions
Student Boris Schmiedlehner
Language English
Supervisors Biagio Cosenza
Description Energy and power consumptions have become very important for nowadays architectures, and it is also important for graphics applications based on OpenGL to know how much energy consumes a given algorithm. In fact, different rendering algorithms, having similar performance (fps and latency) and visual quality may show very different energy and power consumptions on the GPU.
For instance, it’s known that the power consumption of an external memory access is substantially higher than both floating-point and integer operations.
The goal of this project is to code different test rendering algorithms (in OpenGL) and to run them on the GPU. Each proposed code will be evaluated according to its visual quality, performance, and energy consumption.
  • Familiarize with OpenGL and study common rasterization-based rendering algorithms
  • Implement a set of test applications focusing on memory accesses and computation
  • Measure Energy and Power consumptions for the implemented codes (details on how to measure power/energy will be given during the thesis)
Theoretical skills Computer Graphics
Practical skills Good C programming skills


Webinterface for FLD
Number of students Martin Klotz
Supervisor Thomas Fahringer
Language English or German
Description The FLD – documentation of research done – is an university and inter-university collection of the active research done at the divers institutes. Conference papers as well as editor-ships and public works are recorded.
This bachelor thesis should create an interface for entering all necessary information into an own database, while it provides and validates(!) most information out of a given DOI-Link and IEEE/Springer/ACM/DBLP libraries. It should generate BibTeX and an overview/report.
The used back-end (frameworks/languages/own things/…) can be discussed.Die FLD – Forschungsleistungsdokumentation – ist eine universitaere und interuniversitaere Zusammenfassung der aktiven Forschung. Hier werden nicht nur Papers von Konferenzen eingetragen, sondern auch Editorenschaften und   Oeffentlichkeitsarbeit.
Diese Bachelorarbeit soll nun ein Interface zum Eintragen aller notwendigen Informationen anbieten, wobei moeglichst vieles automatisch aus DOI-Link bzw IEEE/Springer/ACM/DBLP-Bibliothek generiert und vor allem auch ueberprueft, werden soll. Die Implementation soll sowohl BibTeX als auch eine Uebersicht ausgeben koennen.
Welches Back-End verwendet werden soll (Framework/Sprache/eigenes…) ist dem Studenten, in Absprache mit dem Betreuer, selber ueberlassen.
  • Read background literature (given by supervisor)
  • Evaluate information required (with supervisor)
  • Build up a “simple” interface and the output.
  • Evaluate information retrievable by DBLP/…
  • Build a system to retrieve information
  • Test the tool.
Theoretical skills Web, Validation
Practical skills Web-developement (framework discussable), Databases
