abstract = {We introduce and analyze different strategies for the
parallel-in-time integration method PFASST to recover from
hard faults and subsequent data loss. Since PFASST stores
solutions at multiple time steps on different processors,
information from adjacent steps can be used to recover after
a processor has failed. PFASST’s multi-level hierarchy
allows to use the coarse level for correcting the
reconstructed solution, which can help to minimize overhead.
A theoretical model is devised linking overhead to the
number of additional PFASST iterations required for
convergence after a fault. The potential efficiency of
different strategies is assessed in terms of required
additional iterations for examples of diffusive and
advective type.},
