Abstract:   Petascale systems have already imposed significant challenges for scaling the existing algorithms to the entire system. The situation will continue and worsen in exascale ones with billion-way concurrency, and we need radical changes in the way we think about scalable parallel algorithms. The session will offer three talks on such algorithms for extreme scale in practical computations, representing different facets of novel core parallel algorithms for petascale machines moving towards exascale, including dense and sparse linear solvers, as well as hierarchical low-rank approximation.
