Curriculum Vitae

Andrés Goens received a Bachelor of Science degree in Physics and one in Mathematics from RWTH Aachen University in Germany in 2012. In 2014 he received his Master's degree in Mathematics also from RWTH Aachen University.
In October 2014 he joined the Chair for Compiler Construction at cfaed in TU Dresden as a Ph.D. student.

In the field of computer science, Goens has worked on numerous projects including the FLINT fast library for number theory, as part of the DFG Priority program SPP1489 with Universtität Kaiserslautern. Between 2013 and 2014 he worked optimizing memory allocation for multicore architectures with the Institute for Communication Technologies and Embeded Systems (ICE) at RWTH Aachen University.

Open Topics

Some possible topics for a Bachelor/Master/Diploma Thesis or SHK/WHK. Projects adaptable depending on level (just ask):

  • MIMO Iterative Decoder as KPN:

    Kahn process networks
    (KPN) are an abstraction for modeling computation which makes communication patterns explicit. They can be used to analyze applications and automatically deploy it to diverse, parallel and heterogeneous platforms. In this project you would port a MIMO Decoder to a KPN formalism and collaborate to modify it for being an iterative decoder. 

    Requirements: Good knowledge of C/C++
    Beneficial: background in signal processing

  • Synchronous data flow subgraph recognition:

    Synchronous data flow (SDF) is a way of modeling computation in which so-called actors execute in parallel and exchange fixed amounts of data in a defined manner. They can be seen as a special case of Kahn process networks, a formalism which does not require defined, fixed exchanges of data. This behavior allows greater analysis to be done to optimize execution of algorithms expressed as SDF. In this project you would use static code analysis (control- and dataflow) to recognize this behavior, allowing for greater optimization in executing algorithms.

    Requirements: Good knowledge of C/C++ or  Haskell (fun project!) or Python (maybe, ask me!), 
    Beneficial: basic compiler construction knowledge (control-flow graph, data-flow analysis)

  • Symmetries in Architectures:

    Computer architectures are growing to include several different processing cores. Mostly, however, many of the cores are identical, which gives symmetries to the architectures. In this project you would use the mathematical methods of group theory to exploit these symmetries. You would work using the GAP software tool

    Requirements: Programming experience (any language), mathematical affinity
    Beneficial: Basic knowledge of rigorous mathematics, in particular, group theory
