Description	Since clock speeds are no longer increasing, time integration is becoming a sequential bottleneck. The multigrid reduction in time (MGRIT) algorithm is an approach for exploiting parallelism in the time dimension that is designed to build on existing codes and time integration techniques. The XBraid library is an open source implementation of MGRIT. One important technique used by current simulation codes is adaptivity in both space and time. In this talk, we discuss approaches taken in XBraid to support adaptivity by exploring several application problems that employ a combination of mesh refinement, mesh motion, and temporal refinement.
