In this talk we highlight some recent progress in extending algebraic multigrid preconditioning to more complex applications, focussing on high-order and non-conforming discretizations, and highlighting success on accelerated platforms (GPU). We also present several challenges where research on algebraic methods would be enhanced through collaboration in the Joint Lab.

Improving data locality in communication avoiding LU and QR factorizations
In previous work we have shown that communication avoiding algorithms combined with dynamic scheduling lead to good performance on multicore architectures. In this work, we investigate the possibility of combining static and dynamic scheduling as well as improving data locality in communication avoiding LU and QR factorizations. We evaluate the performance obtained on a single node of power 5 and power 7 machines.
