Title Practical Manycore Pivoting
Abstract Strong scaling of sparse linear solvers on manycore architectures requires a solution to the latency bottleneck of traditional threshold partial pivoting. We describe our experiments using new pivoting heuristics on difficult real world problems. These include both multilevel a posteriori ("try-it-and-see") approaches that seek to avoid pivoting and communication avoiding variants that work with a representative subset of the data.
