high performance computing on graphics processing units: hgpu.org

All modern processors include a set of vector instructions. While this gives a tremendous boost to the performance, it requires a vectorized code that can take advantage of such instructions. As an ideal vectorization is hard to achieve in practice, one has to decide when different instructions may be applied to different elements of the […]

Iterative stencil computations are important pattern of computations in different computational fields such as physics or chemistry simulations. A stencil computation repeatedly updates each point of a d-dimensional grid as a function of itself and its near neighbors. As the demand for more and more compute power is growing rapidly in different fields of research, […]

We present clRNG, a library for uniform random number generation in OpenCL. Streams of random numbers act as virtual random number generators. They can be created on the host computer in unlimited numbers, and then used either on the host or on other computing devices by work items to generate random numbers. Each stream also […]

Since DARPA Urban Challenge 2007 (DUC), the development of autonomous vehicles has attracted increasing attention from both academic institutes and the automotive industry. It is believed that autonomous vehicles sophisticated and reliable enough would redefine mobility. The motion planner and sensor simulation presented in this thesis are intended to contribute to this prospect. The task […]

Multi-task learning (MTL) for deep neural network (DNN) multilingual acoustic models has been shown to be effective for learning parameters that are common or shared between multiple languages[1, 2]. In the MTL paradigm, the number of parameters in the output layer is large and scales with the number of languages used in training. This output […]

MOTIVATION: To obtain large-scale sequence alignments in a fast and flexible way is an important step in the analyses of next generation sequencing data. Applications based on the Smith-Waterman (SW) algorithm are often either not fast enough, limited to dedicated tasks or not sufficiently accurate due to statistical issues. Current SW implementations that run on […]

Passwords are still by far the most widely used form of user authentication, for applications ranging from online banking or corporate network access to storage encryption. Password guessing thus poses a serious threat for a multitude of applications. Modern password hashes are specifically designed to slow down guessing attacks. However, having exact measures for the […]

Exascale performance requires a level of energy efficiency only achievable with specialized hardware. Hence, to build a general purpose HPC system with exascale performance different types of processors, memory technologies and interconnection networks will be necessary. Heterogeneous hardware is already present on some top supercomputer systems that are composed of different compute nodes, which at […]

Many eigenvalue and eigenvector algorithms begin with reducing the input matrix into a tridiagonal form. A tridiagonal matrix is a matrix that has non-zero elements only on its main diagonal, and the two diagonals directly adjacent to it. Reducing a matrix to a tridiagonal form is an iterative process which uses Jacobi rotations to reduce […]
