Detailed Description

MPI island class.

This island class will dispatch evolutions to participants to an MPI cluster. This class can be used like any other island class, the only difference being that before calling any evolution a pagmo::mpi_environment instance must have been created. More information about the MPI support in PaGMO is available in this page.

NOTE: this class is available only if PaGMO was compiled with MPI support.

Member Function Documentation

base_island_ptr pagmo::mpi_island::clone ( ) const

virtual

Clone method.

Provided that the derived island implements properly the copy constructor, virtually all implementations of this method will look like this:

return base_ptr(new derived_island(*this));

Returns: pagmo::base_island_ptr to a copy of this.

Implements pagmo::base_island.

Definition at line 88 of file mpi_island.cpp.

std::string pagmo::mpi_island::get_name ( ) const

virtual

Return a string identifying the island's type.

Returns: the string "MPI island".

Reimplemented from pagmo::base_island.
