Add to ORKGOne of the main principles in the new FEM package FEAST is a recursive Divide and Conquer strategy which in combination with the generalized solver approach SCARC allows a successive decomposition of 'global' problems into smaller 'local' subproblems. On the lowest-level 'local' patches, highly regular data structures are preferred which enable the use of high-performance Numerical Linear Algebra tools as ingredients in multigrid solvers. Realistic MFLOP rates are demonstrated for typical components: matrix-vector multiplication, preconditioners, vector operations as DAXPY, etc. Finally, we shortly introduce our new matrix-vector techniques which are able to exploit a high percentage of the available peak performance on modern hardware plat...
