ML-based profile analysis of CUDA programs' compiler flag impact
Bækken, August Landgraff (Master thesis, 2018)With the recent successes and interest in machine learning, this project aims to investigate whether machine learning methods can be used to improve compiler optimization selection. Compiler optimization is hard because ... -
Modeling Communication on Multi-GPU Systems
Spampinato, Daniele (Master thesis, 2009)Coupling commodity CPUs and modern GPUs give you heterogeneous systems that are cheap, high-performance with incredible FLOPS counts. Recent evolution of GPGPU models and technologies make these systems even more appealing ... -
Multi-GPU sliding tile puzzle solving with GA*, Groute and Abstract Zobrist Hashing
Pettersson, Håvard (Master thesis, 2018)The A* algorithm has been a key search algorithm and part of AI literature for a long time. It has applications in computational biology, natural lan- guage processing, pathfinding, puzzle solving, and more. The complexity ... -
Online Task Scheduling on Heterogeneous Clusters: An Experimental Study
Rosenvinge, Einar Magnus (Master thesis, 2004)We study the problem of scheduling applications composed of a large number of tasks on heterogeneous clusters. Tasks are identical, independent from each other, and can hence be computed in any order. The goal is to execute ... -
OpenACC-based Snow Simulation
Mikalsen, Magnus Alvestad (Master thesis, 2013)In recent years, the GPU platform has risen in popularity in high performance com-puting due to its cost effectiveness and high computing power offered through its manyparallel cores. The GPUs computing power can be harnessed ... -
Optimizing & Parallelizing a Large Commercial Code for Modeling Oil-well Networks
Rudshaug, Atle (Master thesis, 2008)In this project, a complex, serial application that models networks of oil wells is analyzed for today's parallel architectures. By heavy use of the profiling tool Valgrind, several serial optimizations are achieved, causing ... -
Optimizing 3D Finite Difference Solvers for the Elastic Wave Equation for Modern GPUs
Haugdahl, Tor Andre (Master thesis, 2022)Partielle Differensialligninger (PDEer) omfatter særdeles viktige matematiske verktøy for å modellere reelle fenomener slik som jordskjelv og bølgeforplantning. Finte Difference Metoden (FDM) er en numerisk metode som ... -
Optimizing a High Energy Physics (HEP) Toolkit on Heterogeneous Architectures
Lindal, Yngve Sneen (Master thesis, 2011)A desired trend within high energy physics is to increase particle accelerator luminosities,leading to production of more collision data and higher probabilities of finding interestingphysics results. A central data analysis ... -
Parallel Methods for Real-Time Visualization of Snow
Saltvik, Ingar (Master thesis, 2006)Using computer generated imaging is becoming more and more popular in areas such as computer gaming, movie industry and simulation. A familiar scene in the winter months for most us in the Nordic countries is snow. This ... -
Parallel Seismic Inversion for Shared Memory Systems
Hysing, Andreas Dreyer (Master thesis, 2010)In this thesis will explore how a scientific application forseismic inversion can take advantage of multi-core programming on x86 architecture. The thesis will focus on most effective domain divisions, communication patterns ... -
Parallel Techniques for Estimation and Correction of Aberration in Medical Ultrasound Imaging
Herikstad, Åsmund (Master thesis, 2009)Medical ultrasound imaging is a great diagnostic tool for physicians because of its noninvasive nature. It is performed by directing ultrasonic sound into tissue and visualizing the echo signal. Aberration in the reflected ... -
Parallelizing Particle-In-Cell Codes with OpenMP and MPI
Larsgård, Nils Magnus (Master thesis, 2007)Today's supercomputers often consists of clusters of SMP nodes. Both OpenMP and MPI are programming paradigms that can be used for parallelization of codes for such architectures. OpenMP uses shared memory, and hence is ... -
