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:
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
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:
ELEMENT: use cost measurement on elements
ELEMENT_POINT: use cost measurement on both elements and points
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:
output/develop/preloop_diagnosis.log for runtime and memory
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.
