Container class for multiple, consistent InterpolationSurrogateData objects.
InterpolationSurrogateDataSet< V, M > & m_data
void set_work_bounds(unsigned int &n_begin, unsigned int &n_end) const
Set the starting and ending global indices for the current subenvironment.
const InterpolationSurrogateData< V, M > & get_default_data() const
Helper function to grab representative dataset from m_data.
Base class for builders of surrogates.
void partition_work()
Partition the workload of model evaluations across the subenvironments.
void build_values()
Execute the user&#39;s model and populate m_values for the given n_points.
void sync_data(std::vector< unsigned int > &local_n, std::vector< double > &local_values, InterpolationSurrogateData< V, M > &data)
Take the local values computed from each process and communicate.
void compute_strides(std::vector< int > &strides) const
Helper function to compute strides needed for MPI_Gatherv.
Build interpolation-based surrogate.
std::vector< int > m_njobs
Cache the amount of work for each subenvironment.
void set_domain_vector(unsigned int n, V &domain_vector) const
Provide the spatial coordinates for the global index n.
