vector_d stan::math::mpi_parallel_call< call_id, ReduceF, CombineF >::broadcast_vector ( const vector_d &  data )

inlineprivate

Broadcasts an Eigen vector to the cluster.

Meta information as the data shape is treated as static data and only transferred on the first call and read from cache subsequently. This static shape data is stored with the meta_cache_id label.

Template Parameters

meta_cache_id

item label for static shape data

Parameters

data	vector to be broadcasted from the root and a dummy argument on workers

Returns

broadcasted vector originating from the root
