Input Parameters
Most Parthenon behavior is controlled via an input file, generally named
parthinput.<problem-name>
. Parameters in this file take the form
param = value
, with a particular type for each parameter set in the
Parthenon code.
Parameters are split into blocks, denoted by bracketed names
(<blockname>
). All Parthenon-specific parameters are in blocks named
<parthenon/x>
. Below is an incomplete list of some parameters
Parthenon accepts, split by block.
<parthenon/job>
General parthenon options such as problem name and parameter handling.

Name of this problem or initialization, prefixed to output files.
Produce a parameter file containing all parameters known to Parthenon. Set to true for an output file named parthinput.archive. Set to timestamp for a file with a name containing a timestamp.

<parthenon/time>
Options related to time-stepping and printing of diagnostic data.
<parthenon/mesh>
See the Adaptive Mesh Refinement documentation for details of the required
parameters in <parthenon/mesh>
and <parthenon/meshblock>
.

If set to false, sparse variables will always be allocated, see also Run-time
Global (for all sparse variables) threshold to trigger allocation of a variable if cells in the receiving ghost cells are above this value.
Global (for all sparse variables) threshold to trigger deallocation if all active cells of a variable in a block are below this value.
First deallocate a sparse variable if the dealloc_threshold has been met in this number of consecutive cycles.
