inparam.advanced.yaml

It is unlikely that you will need to change anything in this file, as the options are quite technical and likely of limited interest to the casual user.

verbosity

verbose:
    channel: STDOUT
    level: ESSENTIAL
    warnings: true
    loop_info_interval: 1000
    stability_interval: 1

mpi

mpi:
    nproc_per_group: 1
    weight_for_load_balancing: ELEMENT_POINT
    plot_domain_decomposition: false

weight_for_load_balancing may be ELEMENT_POINT (using micro-benchmark for METIS in Stage II based on element and point evaluation), ELEMENT (same, but ignore point evaluation cost) or NR (reuse the same Nr-based weights from Stage-I without timing, this produces a reproducible partition for integration tests).

developers

develop:
    diagnose_preloop: true
    max_num_time_steps: 0
    time_limit_for_fftw_planning: 60.
    fftw_lucky_numbers: true

Update max_num_time_steps if you want to make sure that the code will at least run through a small number of timesteps, e.g., 10, without becoming unstable.
