Abstract: Numerical linear algebra is at the heart of scientific and industrial
discoveries. The forthcoming arrival of the exascale era provides
tremendous opportunities and challenges for further development of
algorithms and software extreme-scale computing. This minisymposium
emphasizes problem reformulations, algorithm redesigns and
code refactorings for the efficient use of high performance computers.
Topics range from direct methods, iterative methods, preconditioning,
and the emerging fast algorithms for both dense and sparse
algebraic systems. The speakers will present various techniques to reduce
communication, synchronization and memory footprint.
Performance of the new algorithms will be demonstrated on modern manycore
parallel machines.
