Open Thesis Topics
Benchmarking of VAST protocol flavors for ML workloadsApply
A VAST Storage system will be installed as part of the new KISSKI data center. VAST storage systems offer different protocol flavours to access the storage backend, i.e. NFS, S3, SMB, and mixed. Since projects at the new data center should be executed in an efficient way, it is important to gain some insights in the potential performance of machine learning workloads. The proposed thesis will fill this gap and provide recommendations for future projects.
Prototype for GPU computing for particle transport simulations using LIGGGHTSApply
LIGGGHTS is a common code used for the simulation of macroscopic particles. It is based on the well-known molecular dynamics code LAMMPS. The variant used within the thesis is the academic fork LIGGGHTS-PFM which is under current development. Since LAMMPS already has some modules for GPU processing, it is the goal of the thesis to modify LIGGGHTS-PFM to make use of these capabilities. In a first step the best strategy for implementing LIGGGHTS-PFM on GPUs should be evaluated. Based on this a concept and initial steps of the implementation are expected. However, it is not required that all features of LIGGGHTS-PFM are implemented within the scope of the thesis. It is expected that the enhancement will improve the run-time performance and pave the road to particle simulations on GPUs. General programming experience is required. Knowledge in GPUcomputing and particle transport is beneficial but not mandatory.
Implementation of a precice-Adapter for the particle transport simulator LIGGGHTSApply
Precice as already presented at the GöHPCoffee is a multiphysics framework which allows the combination of various simulation codes to perform coupled simulations. These can both include coupled thermal problems or topics related to fluid structure interaction. So far, there exists no possibility to perform a coupled particle simulation using preCICE since the only particle solver is not publicly available. It is the aim of this thesis to mitigate this limitation by implementing a precice-adapter for the particle solver LIGGGHTS-PFM. One possibility could be the modification of an existing OpenFOAM-adapter in preCICE. In addition, the thesis will compare the achievable performance with other coupling libraries using LIGGGHTS and its derivatives. General programming experience is required. Knowledge in simulation technology and particle transport especially in LIGGGHTS is beneficial but not mandatory.
