GPU Acceleration of Equations Assembly in Finite Elements Method -- Preliminary Results
Popis výsledku v původním jazyce
The finite element method (FEM) is widely used for numerical solution of partial differential equations. Two computationally expensive tasks have to be performed in FEM -- equations assembly and solution of the system of equations. We present mapping ofthe equations assembly problem for StVenant-Kirchhoff material to GPU computation model and show results of its early implementations outperforming our single core CPU implementation by factor of 15. Moreover, presented method used for equations assemblyproblem solution is more general and can be considered as a technique to manage complex composition of medium-grained operations with different requirements of GPU resources.
