Description
  • This article deals with the method of algebraic multigrid and its parallelization on GPU. Algebraic multigrid is a sparse matrix iterative solver, which finds the solution by solving also restricted versions of the original problem. The main difference from more widely known geometric multigrid is that it can create the restricted problems without any knowledge about the matrix origin and therefore it can be used for larger range of problems. The article farther presents possibilities how to parallelize this algorithm on multicore CPU architecture and on GPU. Finally it also shows speedup obtained by the GPU parallelization.
