Open Theses

There are various open topics for bachelor's theses, master's theses, guided research, or HiWi positions. Good knowledge of data structure design and fluent programming skills in C++ are highly recommended.

Topics are available in the following areas:

  • Unifying query code generation for NVidia and AMD GPUs using LLVM
  • Light-weight indexing of relational (temporal) data
  • Implementation and evaluation of geo spatial index structures
  • In-memory data structure design for heterogeneous systems
  • Probabilistic data structures and algorithms for GPUs
