Do not require strict cache equality when finding duplicates


Alias: none

Argument(s): none

Required/Optional Description of Group Dakota Keyword Dakota Keyword Description
Optional cache_tolerance Specify tolerance when identifying duplicate function evaluations


By default, Dakota's evaluation cache and restart capabilities are based on strict binary equality. This provides a performance advantage, as it permits a hash-based data structure to be used to search the evaluation cache. However, deactiving strict equality may prevent cache misses, which can occur when attempting to use a restart file on a machine different from the one on which it was generated.
