List of possible topics

Possible themes with some suggested materials to start with:


1. Parallel Scientific Applications and Concurrent Computing (eero at


  • deal.II — an open source finite element library

  • Ways for parallelising serial python and numpy codes
  • Multi-GPGPU Computing (with focus on speeding up weather forecast calculations) -- GPU memory-mapping restructuring for better overlap between data movement and calculations
  • Intel Xeon Phi architecture for speeding up calculations
  • Computing for multicore systems (olegus at
    • Charm++


2. Parallel Scientific Applications and Concurrent Computing (benson punkt muite at ut punkt ee)


  • Scripting and high level language interfaces (eg Java and Python) to the Message Passing Interface and/or to OpenCL
  • Information security on distributed systems
  • Automatic performance tuning of numerical algorithms (eg. Spiral, Atlas  or FFTW )
  • In-situ visualization of solutions to differential equations on GPUs/Xeon Phi and/or multi cpu computers
  • Efficient time integration schemes, geometric integration schemes
  • Particle methods for differential equations
  • Parallel integral equation evaluation for volume rendering
  • Low power efficient heterogeneous computing; comparison of tuning for power efficiency and tuning for speed
  • Good parallel software development practices
  • Testing and improvement of FortranCL 
  • Financially sustainable open source parallel software development models and practices
  • Testing and improvement of Seedme for distributed computing
  • Testing MPPA accelerators such as Kalray and Parallela
  • Testing FPGAs from Altera and Xilinix
  • Parallel Graph Algorithms, for example GraphBLAS

3. Peer-to-Peer (P2P) Computing Architectures (Artjom Lind)

Covering the topics related to distributed computing in peer-to-peer networks. Here I will focus you on own lab framework, however you can propose different topic (some existing framework with similar features or your own design).

  • Individual topic -> Contact me!
  • Friend-to-Friend (F2F) Platform


4. Applied Computer Vision (CV) (Artjom Lind)

Mostly the topics related to the application of latest results in CV. In this area we mostly use OpenCV library, which is recommended but not obligatory. The several topics we can focus on:

  • Structure from motion
  • Object detection/classification
  • Object tracking
  • Optical Character Recognition (OCR)
  • Augmented Reality

 More information ...

5. Parallel Machine learning algorithms (Artjom Lind, Oleg Batrashev, Amnir Hadachi, Benson Muite)


  • Machine digitization and translation for Estonian and non-latin scripts such as Arabic / Cyrillic / Chinese / Farsi / Hebrew / Hindi / Japanese / Korean
  • Character recognition algorithms
  • Evaluating Petuum


6. Exploratory search (Dimitri Danilov)

  • Collaborative search
  • Search Patterns
  • New Development in Search Engines
  • The Vision of Ted Nelson (the inventor of the internet?)
  • Xanadu (and undanax)
  • Graph Based Information Storage
  • New Search Interfaces in Mozilla (practical and theoretical topics available)
  • Machine learning based topic modeling in text documents (using the program Mallet).
  • More topics on demand


7. Modeling and analyzing semantic trajectories (Amnir Hadachi)

8. Mobility data modelling (Toivo Vajakas)

Fast data structure for trajectory data (further development of existing code)
o    Currently existing code for direct read of 1 individual trajectory
o    Add support for batch full-scan and batch subset.
o    Add support for indexing by time and space – to avoid (with high probability) the analysis of trajectories that do not intersect with time-space volume of given query.
Exploratory data analysis on mobile positioning data, using results of Jilles Vreeken group (JV was a speaker on ESSCASS summer school)
o    Separation of time of each person as „currently in routine“ and „non-typical behavior (tourist mode)“.
o    Describe the data, ie the behavior of radio network combined with behavior of people -- pattern mining based on information theory.
o    Clustering of (relatively small) directed graphs, each edge and vertex has also attributes. (graphs are HMM of humans in timespace „states“ like work and home, after removing absolute location and travel direction info (but keeping relative travel distance info)
o    Clurstering of vertices in directed graphs (states of HMM in previous entry). Graphs are HMM of humans in timespace „states“ like work and home, after removing absolute location and travel direction info (but keeping relative travel distance info). Clustering of states gives something like „here many people spend there night“, „many people come here for work“, ...
Combination of traffic simuluation package and data from mobile positioning data, to get local traffic density estimates.

9. Mobility data modeling and representation (Amnir Hadachi)
