Detailed Description

Sample derived interface class for testing parallel simulator plug-ins using assign_rep().

The plug-in ParallelDirectApplicInterface resides in namespace SIM and uses a copy of textbook() to perform parallel parameter to response mappings. It is used to demonstrate plugging in a parallel direct analysis driver into Dakota in library mode. Test input files can then use an analysis_driver of "plugin_textbook".

Member Function Documentation

test_local_evaluations()

void test_local_evaluations ( Dakota::PRPQueue &  prp_queue )

invokes wait_local_evaluations() (no special nowait support)

For use by ApplicationInterface::serve_evaluations_asynch(), which can provide a batch processing capability within message passing schedulers (called using chain ApplicationInterface::serve_evaluations() from Model::serve() from IteratorScheduler::run_iterator()).
