Efficient computation of constrained parameterizations on parallel platforms
Constrained isometric planar parameterizations are central to a broad spectrum of applications. In this work, we present a non linear solver developed on OpenCL that is efficiently parallelizable on modern massively parallel architectures. We establish how parameterization relates to mesh smoothing and show how to ciently and robustly solve the planar mesh parameterization problem with […]

An Embedding Method for Interactive Simulation on Dynamic Surfaces
Numerical simulation on curved surfaces enables the dynamic texturing of three-dimensional objects. In this thesis, I introduce methods for the realtime simulation and visualization of intrinsic fluid dynamics on deforming surfaces. These novel techniques support arbitrary, including open or nonorientable, surfaces and are universally applicable to a wide range of partial differential equation (PDE) problems […]

Towards Rapid Prototyping of Parallel and HPC Applications (GPU Focus)
Developing on highly parallel architectures is hard, time consuming, error prone, takes a lot of developers’ focus and effort to producing a production quality application. This is counter productive and results are unknown in advance whether it is worth it to go through such experience. In this work, we will take a complete overview of […]

GPU-CC: a Reconfigurable GPU Architecture with Communicating Cores
GPUs have evolved to programmable, energy efficient compute accelerators for massively parallel applications. Still, compute power is lost in many applications because of cycles spent on data movement and control instead of computations on actual data. Additional cycles can be lost as well on pipeline stalls due to long latency operations. To improve performance and […]

Point-wise Adaptive Filtering for Fast Monte Carlo Noise Reduction
Monte Carlo based photorealistic image synthesis has proven to be one of the most flexible and powerful rendering techniques, but is plagued with undesirable artifacts known as Monte Carlo noise. We present an adaptive filtering method designed for Monte Carlo rendering systems that counteracts noise while respecting sharp features. The filter operates as a post-process […]

Optimization procedures during parallelization of specialized software for fluid flow simulations
Modern fluid flow simulations can be extremely complex and computationally demanding. Using GPU devices (Graphics Processing Unit) they can execute up to several tens of times faster and simulations can be observed interactively. In this study the basic principles of GPU programming are applied to the implementation of lattice Boltzmann (LB) method. The software that […]

Large Scale Physical Modeling Sound Synthesis
Sound synthesis based on physical models of musical instruments is, ultimately, an exercise in numerical simulation. As such, for complex systems of the type seen in musical acoustics, simulation can be a computationally costly undertaking, particularly if simplifying hypotheses, such as those of traveling wave or mode decompositions are not employed. In this paper, large […]

GPU-Accelerated Real-Time Visualization and Interaction for Coupled Fluid Dynamics
For real-time applications (dynamic data-driven applications systems like computer-assisted surgery, command and control, etc.), it is necessary to design fast or strongly-accelerated computational approaches. Reduced-order modeling (ROM) is a candidate methodology that summarizes all the parameter-dependent PDE solutions into an easy-to-compute condensed form. ROM usually requires an offline learning process that returns the essential components […]
