Member Function Documentation

virtual void sstmac::sw::task_mapper::init_factory_params ( sprockit::sim_parameters *  params )

virtual

Reimplemented in sstmac::sw::coordinate_task_mapper, sstmac::sw::dumpi_task_mapper, sstmac::sw::random_task_mapper, sstmac::sw::node_id_task_mapper, and sstmac::sw::hostname_task_mapper.

virtual void sstmac::sw::task_mapper::map_ranks ( const app_id &  aid, const ordered_node_set &  allocation, int  ppn, std::vector< node_id > &  result, int  nproc  )

pure virtual

Assign processes to nodes.

Parameters

aid	The application ID for the application whose processes are being indexed
nodes	is the set of unique nodes to be used for the allocation
ppn	is the nominal number of processes allocated on each node.
result	is the resulting vector of length nodes (size nproc)
nproc	the total number of processes to allocate

Exceptions

value_error	if nodes.empty()
value_error	if ppn <= 0
value_error	if nodes.size()*ppn < nproc

Implemented in sstmac::sw::random_task_mapper, sstmac::sw::dumpi_task_mapper, sstmac::sw::block_task_mapper, sstmac::sw::coordinate_task_mapper, sstmac::sw::round_robin_task_mapper, sstmac::sw::hostname_task_mapper, and sstmac::sw::node_id_task_mapper.
