Asynchronous One-Level and Two-Level Domain Decomposition Solvers
Christian Glusa, Paritosh Ramanan, Erik G. Boman +2
Parallel implementations of linear iterative solvers generally alternate between phases of data exchange and phases of local computation. Increasingly large problem sizes on more h…
