Parallel-in-time performance analysis

Python tool for task graph based performance analysis of parallel-in-time methods. Currently the methods

  • Parareal [1]
  • Parallel full approximation scheme in space and time (PFASST) [2]
  • Multigrid reduction in time (MGRIT) [3]

are supported.

The model was compared to the following parallel-in-time libraries:
