matrix_d stan::math::mpi_parallel_call< call_id, ReduceF, CombineF >::scatter_matrix ( const matrix_d &  data )

inlineprivate

Scatters an Eigen matrix column wise over 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	matrix to be scattered column-wise and a dummy argument on workers.

Returns

matrix chunk for a given worker.
