To maintain compatibility with current workflows while adding additional functionality to the workflow, we intend to change the way perturbed source parameters are passed to the components of the slurm ground motion workflow.
Changes to implement
To present the parameters to slurm workflow in a way that they can be used by the appropriate part of the workflow, we have decided that changes should be made to Pre Processing such that the user must specify which part of the workflow each parameter belongs to during srf creation.
These changes will then flow on to simulation installation and subsequently submission to the workflow.
User input
The parameters will have to be given in the additional parameters yaml (as passed to gcmt2srf), with each parameter and its nominal value forming a key:value pair, and that pair itself being a value in a list where the component of the workflow it belongs to is the key of the list.
The realisation-uncertainty file will remain as it is.
An example is available below:
hf:
sdrop: 50
rvfac: 0.8
bb:
fmin: 0.2
Internal changes
In order to simplify the implementation of this, we have chosen to have every parameter added to the slurm script and passed as an argument to the simulation script, which will then discard any parameters it does not recognize.
