Summary of the dissertation
Title: "Multigranular optimization for heterogeneous multicore systems"
With the increasing complexity of embedded systems and thus their programming, it is becoming more and more difficult to achieve the best possible performance on these systems.Oliver Wolf has developed a methodology with which optimized C code for embedded multicore systems can be generated with the help of cross-level parallelization.
The aim was to decouple algorithm development from optimization for the actual target system. The four levels of abstraction consider the algorithm, code, task and data levels and use increasingly detailed information from the hardware specification to perform specific optimizations. An iterative approach was chosen that allows later levels to refine decisions and settings from previous levels.
Curriculum vitae
- Studied electrical engineering and information technology at KIT
- Degree: Diploma Nov. 2010
- Thesis title: Conception and implementation of heterogeneous communication principles and methods of adaptive function topologies for the Star-Wheels network
- Employee at ITIV from 2011 to April 2017
Research project
- ALMA research project (http://alma-project.eu/)
- The aim of the ALMA EU project was to develop a software solution that can automatically generate parallelized C code for various embedded systems from Scilab/MATLAB programs. The approach was evaluated with applications from image processing and telecommunications on a commercial and a research processor.
- Code generation
- Structure of programs for parallel execution, structure of the control flow and abstraction of hardware properties.
- Optimization of communication
- Sensible placement of communication instructions, consideration of communication models and support of different architectures.
- Parallelization
- Automatic and manual parallelization, consideration of different types of parallelization and ensuring correct execution.
