Asynchronous Truncated Multigrid-reduction-in-time (AT-MGRIT)
Jens Hahne, Ben Southworth, Stephanie Friedhoff
In this paper, we present the new "asynchronous truncated multigrid-reduction-in-time" (AT-MGRIT) algorithm for introducing time parallelism to the solution of discretized time-dep…

Weighted Relaxation for Multigrid Reduction in Time
Masumi Sugiyama, Jacob B. Schroder, Ben S. Southworth +1
Based on current trends in computer architectures, faster compute speeds must come from increased parallelism rather than increased clock speeds, which are currently stagnate. This…
