1. Analysis and optimization of an implementation of hierarchical Tucker tensors
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : The hierarchical Tucker tensor format is a format for approximated tensors which has been decomposed into smaller parts. This structure can be useful in high-dimensional computer simulations. One implementation of this structure is in a library called htlib. READ MORE

2. Efficiently Solving the Exact Cover Problem in OpenMP
University essay from Umeå universitet/Institutionen för datavetenskapAbstract : The exact cover problem is an NP-complete problem with many widespread use cases such as crew scheduling, railway scheduling, benchmarking as well as having applications in set theory. Existing algorithms can be slow when dealing with large datasets however. READ MORE

3. Design and evaluation of a plain MPI-based cluster execution backend for the SkePU 3 skeleton programming framework
University essay from Linköpings universitet/Programvara och systemAbstract : SkePU 3 is a framework for parallel program execution that uses higher order functions called skeletons, which provide a layer of abstraction between user code and the parallel implementation it provides through its backends. The backend that enables SkePU to run on an HPC cluster has a slowdown of a factor two. READ MORE

4. Parallel Kafka Producer Applications : Their performance and its limitations
University essay from Umeå universitet/Institutionen för datavetenskapAbstract : "This paper examines multi-threaded Kafka producer applications, and how the performance of such applications is affected by how the number of producer instances relates to the number of executing threads. Specifically, the performance of such applications when using a single producer instance, shared among all threads, and when each thread is allotted a separate, private instance, is compared.

5. Convection in a spherical shell under rapid rotation: numerical simulations
University essay from KTH/Teknisk mekanikAbstract : A numerical method for solving the buoyancy-driven magneto-convection equations in a rapidly rotating spherical shell is presented. The method is implemented through a FORTRAN 90 program, based on a FORTRAN 66 code written by Hollerbach [International Journal for Numerical Methods in Fluids, 32 (2000)] and partially translated in FORTRAN 90 by Riquier.
