Using performance analysis tools for parallel-in-time integrators -- Does my time-parallel code do what I think it does?
Robert Speck, Michael Knobloch, Sebastian Lührs +1
While many ideas and proofs of concept for parallel-in-time integration methods exists, the number of large-scale, accessible time-parallel codes is rather small. This is often due…
