Relativistic hydrodynamics became a very useful tool in high-energy physics after Landau’s application of this theory for explaining data on proton-proton collisions. It’s later application to heavy ion collisions has been very successful in modeling apparent collective behaviour of hot matter produced in such collisions. This work is a part of an effort of the […]

Field equations can be numerically simulated by approximating a continuous space field by a discrete lattice. There are a number of different lattice geometries that can be used to approximate continuous space which may cause structural artefacts in the simulation. These different lattice structures require the use of different stencil operators to approximate the spatial […]

We report the first CUDA graphics-processing-unit (GPU) implementation of the polymer field-theoretic simulation framework for determining fully fluctuating expectation values of equilibrium properties for periodic and select aperiodic polymer systems. Our implementation is suitable both for self-consistent field theory (mean-field) solutions of the field equations, and for fully fluctuating simulations using the complex Langevin approach. […]

This thesis describes a generative programming system that automatically constructs parallel simulations of complex systems that are based on field equations using finite differencing and explicit Runge-Kutta integration methods. Programming computational simulations by hand for different parallel architectures is both tedious and time consuming. Simulation frameworks struggle to target different architectures without losing performance. Automating […]

In this paper, we have shown that exploitation of the GPU’s massively parallel architecture can dramatically increase the speed of MoM calculations. While the code can certainly be improved, matrix fill speed-up factors are already commonly found to be between 150X-260X. The conjugate gradient solver stands to be improved at this writing but still results […]

Graphical processing units (GPUs) have recently attracted attention for scientific applications such as particle simulations. This is partially driven by low commodity pricing of GPUs but also by recent toolkit and library developments that make them more accessible to scientific programmers. We discuss the application of GPU programming to two significantly different paradigms – regular mesh field […]
