The MPI interface provides error checking and error * handler invocation, but the collective components provide all other * functionality. * * Component selection is done per commuicator, at Communicator * construction time. mca_coll_base_comm_select() is used to * create the list of components available to the compoenent * collm_comm_query function, instantiating a module for each * component that i usable, and sets the module collective function pointers. * mca_coll_base_comm_select() then loops through the list of available * components (via the instantiated module), and uses the * module's coll_module_enable() function to enable the modules, and * if successful, sets the communicator collective functions to the * those supplied by the given module, keeping track of which module it * is associated with. * * The module destructors are called for each module used by the * communicator, at communicator desctruction time. * * This can result in up to N different components being used for a * single communicator, one per needed collective function. * * The interface is the same for inter- or intra-communicators, and * components should be able to handle either style of communicator * during initialization (although handling may include indicating the * component is not available). */ #ifndef OMPI_MCA_COLL_COLL_H #define OMPI_MCA_COLL_COLL_H #include "ompi_config.h" #include "mpi.h" #include "ompi/mca/mca.h" #include "opal/mca/base/base.h" #include "opal/mca/crs/crs.h" #include "opal/mca/crs/base/base.h" #include "ompi/request/request.h" BEGIN_C_DECLS /* ******************************************************************** */ struct ompi_communicator_t; struct ompi_datatype_t; struct ompi_op_t; /* ******************************************************************** */ /** * Collective component initialization * * Initialize the given collective component.
