Efficient simulation of diffusion-based choice RT models on CPU and GPU KU Leuven
In this paper, we present software for the efficient simulation of a broad class of linear and nonlinear diffusion models for choice RT, using either CPU or graphical processing unit (GPU) technology. The software is readily accessible from the popular scripting languages MATLAB and R (both 64-bit). The speed obtained on a single high-end GPU is comparable to that of a small CPU cluster, bringing standard statistical inference of complex ...
Efficient estimation of bounded gradient-drift diffusion models for affect on CPU and GPU KU Leuven
Computational modeling plays an important role in a gamut of research fields. In affect research, continuous-time stochastic models are becoming increasingly popular. Recently, a non-linear, continuous-time, stochastic model has been introduced for affect dynamics, called the Affective Ising Model (AIM). The drawback of non-linear models like the AIM is that they generally come with serious computational challenges for parameter estimation and ...
Quasar: a new heterogeneous programming framework for image and video processing algorithms on CPU and GPU Universiteit Gent
In image and video processing research, rapid prototyping and testing of different variations of an algorithm is quite essential (e.g., to find out if a given algorithm can solve a given problem or work in real-time). In the past decade, the computational performance of graphical processing units (GPUs) has improved significantly, where speed-up factors of 10x-50x compared to single-threaded CPU execution are not uncommon. However, GPU ...

Aggression towards the GP: can we profile the GP–victim? A cross-section survey among GPs KU Leuven
Abstract Background: Aggression against GPs has increased in the past decade. Depending on experience, interpretation, and personality, the interpretation of aggressive patient behaviour will differ among doctors. Aim: To investigate how often GPs experience aggression in a 1-year time span and what the relationship is between the GP’s personality (based on the ’Big Five’ personality traits) and the reporting of aggression. Secondly, to ...
Comparing and combining GPU and FPGA accelerators in an image processing context Vrije Universiteit Brussel
Nowadays, processors alone cannot deliver what computation hungry image processing applications demand. An alternative is to use hardware accelerators such as Graphics Processing Units (GPUs) or Field Programmable Gate Arrays (FPGAs). Applications, however, exhibit different performance characteristics depending on the accelerator. This paper describes the hybrid platform and the programming environment that allows to efficiently create programs ...
A GPU optimization workflow for real-time execution of ultra-high frame rate computer vision applications Universiteit Gent
This work proposes a GPU optimization methodology for real-time execution of ultra high frame rate applications with small frame sizes. While the use of GPUs for offline processing is well-established, real-time execution remains challenging due to the lack of real-time execution guarantees, especially for embedded GPUs. Our methodology introduces guidelines and a workfl ow by focusing on: (a) controlling latency by means of minimization of ...
