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. 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. If some samples use more than one processor, like when there is more processes than samples, there will be outputs that do not contain any data, see main_small_out.json.3 for example.
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.
