RESEARCH ACTIVITIES

The research of the HPC group at the Department of Mathematics and Computer Science of University of Basel, Switzerland concentrates on the following topics:

  • Parallelization
  • Heterogeneity
  • Mapping
  • Scheduling
  • Robustness (fault tolerance)
  • Scalability
  • Verification and validation
  • Reproducibility

of parallel applications executing on small (multi-many cores) to large scale (multi-node) high performance computers.

Other topics of interest include:

  • Data mining
  • Process mining
  • Information security (protection and privacy)
  • System and application monitoring
  • Modeling and simulation of parallel applications and systems.
