The complexity of the design of radio networks has grown with the adoption of modern standards. Therefore, the role of the computer for the faster delivery of accurate results has become increasingly important. In this thesis, novel methods for the planning and automatic optimization of radio networks are developed and discussed. The state-of-the-art metaheuristic algorithms, […]

In the current digital age, the use of cellular automata to simulate natural systems has grown more popular as our understanding of cellular systems increases. Up until about a decade ago, digital models based on the concept of cellular automata have primarily been simulated with sequential rule application algorithms, which do not exploit the inherent […]

Because Cellular Automata (CA) is a dynamic system with inherent parallelism, many studies are focused on mapping CA to the parallel system in order to obtain high performance computing capability, such as using clusters, supercomputers and networks of computers. But the application of these systems are too expensive and difficult to use on the occasions […]

The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) is a general-purpose particle detector and comprises the largest silicon-based tracking system built to date with 75 million individual readout channels. The precise reconstruction of particle tracks from this tremendous amount of input channels is a compute-intensive task. The foreseen LHC beam parameters […]

The Frisch-Hasslacher-Pomeau (FHP) model is a lattice gas cellular automaton designed to simulate fluid flows using the exact, purely Boolean arithmetic, without any round-off error. Here we investigate the problem of its efficient porting to clusters of Fermi-class graphic processing units. To this end two multi-GPU implementations were developed and examined: one using the NVIDIA […]

Graphics processors (GPU – Graphic Processor Units) recently have gained a lot of interest as an efficient platform for general-purpose computation. Cellular Automata approach which is inherently parallel gives the opportunity to implement high performance simulations. This paper presents how shared memory in GPU can be used to improve performance for Cellular Automata models. In […]

The environment around us has many phenomena and has different behaviors according to different parameters, biological, chemical, physical, etc. To represent a simple and abstract reality of this environment we use a concept called environmental modeling. The environmental modeling deals with many environmental problems such as air pollution, diffusion of disease, animal behavior and so […]

Simulation and visualization of particles in real-time can be a computationally intensive task. This intensity comes from diverse factories, being one of them is the O(n^2) complexity of the traversal algorithm, necessary for the proximity queries of all pair of particles that decide the need to compute collisions. Previous works reduced this complexity by considerably […]

Traffic models based on cellular automata have high computational efficiency because of their simplicity in describing unrealistic vehicular behavior and the versatility of cellular automata to be implemented on parallel processing. On the other hand, the other microscopic traffic models such as car-following models are computationally more expensive, but they have more realistic driver behaviors […]

Regular expression matching is a central task in several networking (and search) applications and has been accelerated on a variety of parallel architectures. All solutions are based on finite automata (either in deterministic or non-deterministic form), and mostly focus on effective memory representations for such automata. Recently, a handful of work has proposed efficient regular […]

Traffic forecast has been of practical interest for modern society, mainly in minimizing of jammed traffic effects due to the saturation of roads, as well as predictable the impact of road interventions. In this way, a family of computational methods that represent basic traffic characteristics is based on Cellular Automata (CA). Moreover, the simulation of […]

A recent trend in the development of flood simulation algorithms shows the move toward fast simplified models instead of slow full hydrodynamic models. CADDIES is a research project that aims to develop a real/near-real time pluvial urban flood simulation model using the computational speed of cellular automata (CA) algorithms. This paper presents a component of […]

  • GPU device 0: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • GPU device 1: AMD/ATI Radeon HD 6970 2GB, 880MHz
  • CPU: AMD Phenom II X6 @ 2.8GHz 1055T
  • RAM: 12GB
  • OS: OpenSUSE 13.1
  • SDK: nVidia CUDA Toolkit 6.5.14, AMD APP SDK 3.0
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.3
  • SDK: AMD APP SDK 3.0

Completed OpenCL project should be uploaded via User dashboard (see instructions and example there), compilation and execution terminal output logs will be provided to the user.
