In this report we present a novel approach to model coupling for shared-memory multicore systems hosting OpenCL-compliant accelerators, which we call The Glasgow Model Coupling Framework (GMCF). We discuss the implementation of a prototype of GMCF and its application to coupling the Weather Research and Forecasting Model and an OpenCL-accelerated version of the Large Eddy […]

This paper proposes an end-to-end framework for automatically transforming stencil-based CUDA programs to exploit inter-kernel data locality. The CUDA-to-CUDA transformation collectively replaces the user-written kernels by auto-generated kernels optimized for data reuse. The transformation is based on two basic operations, kernel fusion and fission, and relies on a series of automated steps: gathering metadata, generating […]

The paper presents investigations on the implementation and performance of the finite element numerical integration algorithm for first order approximations and three processor architectures, popular in scientific computing, classical CPU, Intel Xeon Phi and NVIDIA Kepler GPU. A unifying programming model and portable OpenCL implementation is considered for all architectures. Variations of the algorithm due […]

Bisimilarity checking is an important operation to perform explicit-state model checking when the state space of a model under verification has already been generated. It can be applied in various ways: reduction of a state space w.r.t. a particular flavour of bisimilarity, or checking that two given state spaces are bisimilar. Bisimilarity checking is a […]

In this dissertation, we have proposed our solutions to four important and challenging topics in enhancing fluid modeling with turbulence and acceleration: distance field representation of obstacles in fluid, adaptive and controllable turbulence enhancement, Langevin Particles and GPU acceleration in fluid modeling. All these fields aims at creating realistic and fast fluid field which are […]

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 […]
