SamplerReporterTransfer
Transfers data from Reporters on the sub-application to a StochasticReporter on the main application.
Overview
This object is designed to transfer data from postprocessors, vectorpostprocessors, and reporters on the sub-application to the main application. This object must transfer data to a StochasticReporter object.
How It Works
This transfer works similar to MultiAppCloneReporterTransfer whereby creating vector reporter values whose type is based on the type of value being transferred. The name of the reporter values are <stochastic_reporter name>/<transfer name or prefix>:<sub-app reporter object name>:<sub-app reporter value name>. In parallel, the vector that the values are being transferred into are distributed by default. For instance, main_out.json is the output in serial showing all the transferred data; while main_parallel.json, main_parallel.json.1, main_parallel.json.2, and main_parallel.json.3 are the combined data from running on 4 processors. However, this split in files can be avoided if "parallel_type" in the reporter object is set to ROOT. This will gather all the data to the root processor, beware using this option can cause memory issues with very very large stochastic runs.
Dealing with Failed Solves
When performing stochastic analysis with many perturbations of a sub-application, it is sometimes the case where the app receives a set of parameters that makes the solve difficult to converge. With the default configuration of this object, if one of sub-applications' solve fails, the main application will abort. If it is expected that some solves might not converge and aborting the main application is not the desired behavior, the parameter "ignore_solve_not_converge" must be set to true in the MultiApps block (see SamplerFullSolveMultiApp for more details). With this parameter set to true in the multiapp, this object will transfer whatever the last compute values are. To keep track of whether the solve converged or not, the reporter value <stochastic_reporter name>/multiapp_converged is created. See main_out.json as an example.

parallel_type
Default:DISTRIBUTED
C++ Type:MooseEnum
Unit:(no unit assumed)
Options:DISTRIBUTED, ROOT
Controllable:No
Description:This parameter will determine how the stochastic data is gathered. It is common for outputting purposes that this parameter be set to ROOT, otherwise, many files will be produced showing the values on each processor. However, if there are lot of samples, gathering on root may be memory restrictive.
ignore_solve_not_converge
Default:False
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:True to continue main app even if a sub app's solve does not converge.
