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 […]

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 […]

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 […]

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 […]

A principally novel approach towards solving the few-particle (many-dimensional) quantum scattering problems is described. The approach is based on a complete discretization of few-particle continuum and usage of massively parallel computations of integral kernels for scattering equations by means of GPU. The discretization for continuous spectrum of a few-particle Hamiltonian is realized with a projection […]

EMMA is a cosmological simulation code aimed at investigating the reionization epoch. It handles simultaneously collisionless and gas dynamics, as well as radiative transfer physics using a moment-based description with the M1 approximation. Field quantities are stored and computed on an adaptive 3D mesh and the spatial resolution can be dynamically modified based on physically-motivated […]

A fully real-time coherent dedispersion system has been developed for the pulsar back-end at the Giant Metrewave Radio Telescope (GMRT). The dedispersion pipeline uses the single phased array voltage beam produced by the existing GMRT software back-end (GSB) to produce coherently dedispersed intensity output in real time, for the currently operational bandwidths of 16 MHz […]
