high performance computing on graphics processing units: hgpu.org

The amount of content on the Internet is growing rapidly as well as the number of the online Internet users. As a consequence, web search engines need to increase their computing capabilities and data continually while maintaining low search latency and without a significant rise in the cost per query. To serve this larger numbers […]

Energy efficiency has now become the primary obstacle in scaling the performance of all classes of computing systems. Low-voltage computing and specifically, near-threshold voltage computing (NTC), which involves operating the transistor very close to and yet above its threshold voltage, holds the promise of providing many-fold improvement in energy efficiency. However, use of NTC also […]

In this thesis, we study the management of relational data in modern, i.e., asymmetric computer systems. We explore different strategies to identify asymmetries in persistent data, map them to asymmetries in the memory landscape and, eventually, exploit them to increase query processing performance. To this end, we study memory conscious decomposition and storage of data […]

Computer systems equipped with graphics processing units (GPUs) have become increasingly common over the last decade. In order to utilize the highly data parallel architecture of GPUs for general purpose applications, new programming models such as OpenCL and CUDA were introduced, showing that data parallel kernels on GPUs can achieve speedups by several orders of […]

This paper illustrates the design and implementation of a conflict-driven ASP solver that is capable of exploiting the Single-Instruction Multiple-Thread parallelism offered by General Purpose Graphical Processing Units (GPUs). Modern GPUs are multi-core platforms, providing access to large number of cores at a very low cost, but at the price of a complex architecture with […]

The goal of a Knowledge Base-supported Question Answering (KB-supported QA) system is to answer a query natural language by obtaining the answer from a knowledge database, which stores knowledge in the form of (entity, relation, value) triples. QA systems understand questions by extracting entity and relation pairs. This thesis aims at recognizing the relation candidates […]

This dissertation focuses on block cyclic reduction (BCR) type fast direct solvers, graphics processing unit (GPU) computation, and image denoising. The fast direct solvers are specialized methods for solving certain types of linear systems. They take into account specific characteristics of the system and are therefore able to solve the system much more efficiently than […]

Advanced Simulation Library is a free and open source multiphysics simulation software package and a tool for solving Partial Differential Equations. It has significant user base across many areas of engineering and science, from both industrial and academic organizations. ASL utilizes only the methods that allow efficient parallelization: Lattice Boltzmann Methods, Explicit Finite Difference, Matrix […]

Designing hardware is a time-consuming and complex process. Realization of both, embedded and high-performance applications can benefit from a design process on a higher level of abstraction. This helps to reduce development time and allows to iteratively test and optimize the hardware design during development, as common in software development. We present our tool, OCLAcc, […]

Memory performance is of great importance to achieve high performance on the Nvidia CUDA GPU. Previous work has proposed specific optimizations such as thread coarsening, caching data in shared memory, and global data layout transformation. We argue that vectorization based on hyper loop parallelism can be used as a unified technique to optimize the memory […]
