Existing work on accelerating analytic DB query processing with (discrete) GPUs fails to fully realize their potential for speedup through parallelism: Published results do not achieve significant speedup over more performant CPU-only DBMSes when processing complete queries. This paper presents a successful e!ort to better meet this challenge, in the form of a proof-of-concept query […]

Modern commodity processors such as GPUs may execute up to about a thousand of physical threads per chip to better utilize their numerous execution units and hide execution latencies. Understanding this novel capability, however, is hindered by the overall complexity of the hardware and complexity of typical workloads. In this dissertation, we suggest a better […]

The use of neural networks, machine learning, or artificial intelligence, in its broadest and most controversial sense, has been a tumultuous journey involving three distinct hype cycles and a history dating back to the 1960s. Resurgent, enthusiastic interest in machine learning and its applications bolsters the case for machine learning as a fundamental computational kernel. […]

Providing users of HPC systems with a wide variety of up to date software packages is a challenging task. Large software stacks built from source are difficult to manage, requiring powerful package management tools. The Portage package manager from Gentoo is a highly flexible tool that offers a mature solution to this otherwise daunting task. […]

Latent Dirichlet Allocation (LDA) is a popular tool for analyzing discrete count data such as text and images. Applications require LDA to handle both large datasets and a large number of topics. Though distributed CPU systems have been used, GPU-based systems have emerged as a promising alternative because of the high computational power and memory […]

Deep Convolutional Neural Networks have received a lot of attention over the past few years as a promising technique for object classification in images. In this thesis, we implemented the frequency domain convolution for the popular Caffe framework. Deep Convolutional Neural Networks suffer from long training times even on contemporary hardware, which we want to […]

Graph analytics is becoming ever more ubiquitous in today’s world. However, situational dynamic changes in input graphs, such as changes in traffic and weather patterns, lead to variations in concurrency. Moreover, graph algorithms are known to have data dependent loops and fine-grain synchronization that makes them hard to scale on parallel machines. Recent trends in […]

In cryo-electron microscopy (EM), molecular structures are determined from large numbers of projection images of individual particles. To harness the full power of this single-molecule information, we use the Bayesian inference of EM (BioEM) formalism. By ranking structural models using posterior probabilities calculated for individual images, BioEM in principle addresses the challenge of working with […]
