Detailed Description

Member Function Documentation

init_communicators_checks()

void init_communicators_checks ( int  max_eval_concurrency )

inlineprotectedvirtual

Process init issues as warnings since some contexts (e.g., EnsembleSurrModel) initialize more configurations than will be used and DirectApplicInterface allows override by derived plug-ins.

Reimplemented from DirectApplicInterface.

set_communicators_checks()

void set_communicators_checks ( int  max_eval_concurrency )

inlineprotectedvirtual

Process run-time issues as hard errors.

Reimplemented from DirectApplicInterface.

derived_map_ac()

int derived_map_ac ( const String &  ac_name )

derived_map_asynch()

void derived_map_asynch ( const ParamResponsePair &  pair )

protectedvirtual

Python supports batch only, not true asynch (this is no-op)

This is a no-op as all work takes place in wait/test_local_evaluations

Reimplemented from DirectApplicInterface.
