inparam.advanced.yaml#

verbosity#

Parameters for verbosity.

channel#

What: verbose to stdout or a file

Type: string

Only: STDOUT / filename

Default: STDOUT

level#

What: verbosity level

Type: string

Only: NONE / ESSENTIAL / DETAILED

Default: ESSENTIAL

warnings#

What: show/hide runtime warnings

Type: bool

Default: true

loop_info_interval#

What: time step interval to display time loop info

Type: int

Default: 1000

stability_interval#

What: time step interval for stability check

Type: int

Default: 1

Note:

use 1 to precisely locate the origin of instability

mpi#

Parameters for mpi.

nproc_per_group#

What: number of processors in a mpi group

Type: int

Default: 1

Note:

  1. AxiSEM3D uses a two-level MPI structure where the processors are divided into groups to avoid broadcasting a large input dataset (e.g., the Exodus mesh or a large 3D model) on every processor; instead, a large dataset can be stored only on a “leader” processor in each group, which handles data requests from its members

  2. increase this number (from 1 to the number of processors per per node) to save memory

weight_for_load_balancing#

What: weight for load balancing

Type: string

Only: ELEMENT / ELEMENT_POINT / NR

Default: ELEMENT_POINT

Note:

  1. ELEMENT: use cost measurement on elements

  2. ELEMENT_POINT: use cost measurement on both elements and points

  3. NR: notiming, uses Nr(s,z) weights (reproducible)

plot_domain_decomposition#

What: plot domain decomposition

Type: bool

Default: false

Note:

the output netcdf file contains three variables:

  • coords, double, (X, 2), (s,z) of the element centers

  • mpi_rank, int, (X, ), mpi rank of the elements

  • weights, double, (X, ), element weights for decomposition where X is the number of elements

developers#

Parameters for developers.

diagnose_preloop#

What: enable/disable preloop diagnosis

Type: bool

Default: true

Note:

  1. output/develop/preloop_diagnosis.log for runtime and memory

  2. output/develop/cost_measurements.log for cost measurements on elements and GLL points

max_num_time_steps#

What: maximum time steps for running

Type: int

Default: 0

Note:

use 0 to free this limit

time_limit_for_fftw_planning#

What: wall-clock time limit (sec) for FFTW planning

Type: double

Default: 60.

fftw_lucky_numbers#

What: enforce FFTW lucky numbers

Type: bool

Default: true

Note:

FFTW is good at handling logical sizes of the form: n = (2^a)(3^b)(5^c)(7^d)(11^e)*(13^f), where e + f < 2, as called the lucky numbers; users should use true.
