2. 1. High Performance Adaptive Finite Element Methods : With Applications in Aerodynamics

   Author : Niclas Jansson; Johan Hoffman; Johan Jansson; Vincent Heuveline; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The massive computational cost for resolving all scales in a turbulent flow makes a direct numerical simulation of the underlying Navier-Stokes equations impossible in most engineering applications. Recent advances in adaptive finite element methods offer a new powerful tool in Computational Fluid Dynamics (CFD). READ MORE

4. 2. Design of High Performance Computing Software for Genericity and Variability

   Author : Malin Ljungberg; Michael Thuné; Kurt Otto; Hans Petter Langtangen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; coordinate invariant; curvilinear coordinates; symmetry exploiting; generalized Fourier transform; finite difference; expression templates; feature modeling; variability; Beräkningsvetenskap; Scientific Computing;

   Abstract : Computer simulations have emerged as a cost efficient complement to laboratory experiments, as computers have become increasingly powerful. The aim of the present work is to explore the ideas of some state of the art software development practices, and ways in which these can be useful for developing high performance research codes.

5. 3. High-Performance Finite Element Methods : with Application to Simulation of Diffusion MRI and Vertical Axis Wind Turbines

   Author : Van-Dang Nguyen; Johan Hoffman; Johan Jansson; Axel Målqvist; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High performance finite element method; computational diffusion MRI; turbulent flow; vertical axis wind turbine.; Computer Science; Datalogi;

   Abstract : The finite element methods (FEM) have been developed over decades, and together with the growth of computer engineering, they become more and more important in solving large-scale problems in science and industry. The objective of this thesis is to develop high-performance finite element methods (HP-FEM), with two main applications in mind: computational diffusion magnetic resonance imaging (MRI), and simulation of the turbulent flow past a vertical axis wind turbine (VAWT).

6. 4. Autonomous resource management for high performance datacenters

   Author : Abel Souza; Johan Tordsson; Alexandru Iosup; Umeå universitet; []
   Keywords : Datacenters; high performance computing; scheduling; hybrid; Computer Science; datalogi;

   Abstract : Over the last decade, new applications such as data intensive workflows have hit an inflection point in wide spread use and influenced the compute paradigm of most scientific and industrial endeavours. Data intensive workflows are highly dynamic and adaptable to resource changes, system faults, and by also allowing approximate solutions into their models. READ MORE

7. 5. Emerging Paradigms in the Convergence of Cloud and High-Performance Computing

   Author : Daniel Araújo De Medeiros; Ivy Bo Peng; Stefano Markidis; Pawel Herman; Valeria Cardellini; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-performance computing; Kubernetes; airflow; elastic scaling; MPI; S3; Datalogi; Computer Science;

   Abstract : Traditional HPC scientific workloads are tightly coupled, while emerging scientific workflows exhibit even more complex patterns, consisting of multiple characteristically different stages that may be IO-intensive, compute-intensive, or memory-intensive. New high-performance computer systems are evolving to adapt to these new requirements and are motivated by the need for performance and efficiency in resource usage. READ MORE
