SpeedIT

 

Die SpeedIT Tools Bibliothek stellt eine Reihe von beschleunigten Gleichungslösern für dünnbesette Matrizen oder Gleichungen zur Verfügung. Manifold acceleration, e.g. more than an order of magnitude, is achieved with a single reasonably priced NVIDIA Graphics Processing Unit (GPU) that supporst CUDA and proprietary advanced optimisation techniques.

Die Bibliothek kann für ein weites Spektrum von Anwendungsgebieten mit zugrundeliegender 2D und 3D Geometrie, wie numerische Strömungsmechanik, Elektromagnetismus, Themodynamik, Materialwissenschaften, Akustik, Computervisualisierung und -graphik, Robotertechnik, Halbleiterkomponenten und konstrukivem Maschinenbau. Die Bibliothek kann ebenfalls für Probleme ohne definierte Geometrie wie Quantenchemie, Statistik, Stromnetzwerke und andere graphische und chemische Simulationen verwendet werden.

Alle Berechnungen werden mit einfacher oder doppelter Fließkommagenauigkeit durchgeführt werden. Zwei lineare Gleichungslöser und zwei Vorkonditionierer stehen zur Verfügung.

Produktoptionen

 

SpeedIT is distributed in two versions: GPL-based and commercial. The first one, called SpeedIT Classic has been released for demonstration purposes and its performance has not been optimized, it supports also only single precision. New users are encouraged to download and test SpeedIT Classic in their programs to understand the API and installation procedure. Together with SpeedIT Plugin to OpenFoam® anyone can test this version also with OpenFOAM.

SpeedIT

SpeedIT is a library of one of the fastest GPU implementations for Sparse Matrix-Vector Multiplication, Conjugate Gradient and BiConjugate Gradient Stabilized. In average it outperforms CUSP and CUSPARSE by following factors:

SpeedIT eXtreme

SpeedIT eXtreme has the same features as standard version but its internal kernel parameters are opitmized for a given GPU architecture. As such SpeedIT eXtreme takes the full advantage of your GPU card and therefore works fasters.

SpeedIT Multi-GPU


Our results from multi-gpu simulations in OpenFOAM are available at our blog (see vratis.com/blog ).

SpeedIT Classic

SpeedIT Classic implements classical algorithms and works in single precision only.


SpeedIT Plugin to OpenFOAM ®

With our plugin you can accelerate your OpenFOAM simulations by replacing standard iterative solvers with our GPU-accelerated versions. The more iterations to calculate pressure and momentum with Conjugate Gradient or BiConjugate Gradient in a given time steps, the higher the acceleration can be achieved.
