Fast GPU integration algorithm for isogeometric finite element method solvers using task dependency graphs
The integration algorithm in 2D isogeometric finite element method is considered. The higher order B-spline integration takes significant time of the solution. The integration algorithm is analyzed by using the trace theory. The dependency graph from trace theory allows to schedule tasks in concurrent. The efficiency of the algorithm is tested on the isogeometric L2 projection problem.
