Detailed Description

Evaluation manager class for APPSPACK.

The APPSEvalMgr class is derived from APPSPACK's Executor class. It implements the methods of that class in such away that allows DAKOTA to manage the computation of responses instead of APPS. Iterate and response values are passed between Dakota and APPSPACK via this interface.

Member Function Documentation

bool isReadyForWork ( ) const

tells APPS whether or not there is a processor available to perform a function evaluation

Check to see if all processors available for function evaluations are being used. If not, tell APPS that one is available.

References APPSEvalMgr::numWorkersTotal, and APPSEvalMgr::numWorkersUsed.

bool submit ( const int  apps_tag,
const HOPSPACK::Vector &  apps_xtrial,
const HOPSPACK::EvalRequestType  apps_request 
)

performs a function evaluation at APPS-provided x_in

Convert APPSPACK vector of variables to DAKOTA vector of variables and perform function evaluation asynchronously or not as specified in the DAKOTA input deck. If evaluation is asynchronous, map the dakota id to the APPS tag. If evaluation is synchronous, map the responses to the APPS tag.

HOPSPACK::Vector &  apps_f,
HOPSPACK::Vector &  apps_cEqs,
HOPSPACK::Vector &  apps_cIneqs,
string &  apps_msg 
)

returns a function value to APPS

Retrieve a set of reponse values, convert to APPS data structures, and return them to APPS. APPS tags are tied to corresponding responses using the appropriate (i.e., asynchronous or synchronous) map.
