Portrait of Lukas Hübner Lukas Hübner

M.Sc. Lukas Hübner

Research Interests

  • Fault-Tolerance in HPC-algorithms: scalable restoration of data
  • Phylogenetic tree inference
  • Fault-tolerant basic toolbox algorithms (MapReduce, …)
  • Checkpointless fault-tolerance and lossy checkpoint compression
  • Judicious hypergraph partitioning


  • Fault-Tolerant RAxML-NG (FT-RAxML-NG) Fault-tolerant version of the popular RAxML-NG phylogenetic inference tool
  • ReStore (in-memory REplicated STORagE for rapid recovery in fault-tolerant algorithms)
  • Coraxlib (COre RAXml LIBrary) encapsulates common routines used by likelihood-based phylogenetic software
