file_tag


Tag each parameters & results file name with the function evaluation number

Specification

Alias: none

Argument(s): none

Default: no tagging

Description

If this keyword is used, Dakota will append a period and the function evaluation number to the names of the parameter and results files.

Default Behavior If this keyword is omitted, the default is no file tagging.

Usage Tips

  • File tagging is most useful when multiple function evaluations are running simultaneously using files in a shared disk space. The analysis driver will be able to infer the function evaluation number from the file names.
  • Note that when the file_save keyword is used, Dakota automatically renames parameters and results files, giving them tags after execution of the analysis driver if they otherwise would be overwritten by the next evaluation.

Examples

If the following is included in the interface section of the Dakota input:

  parameters_file = params.in
  results_file = results.out
  file_tag

Then for the 3rd evaluation, Dakota will write params.in.3, and will expect results.out.3 to be written by the analysis driver.
