global_get

template<typename ValueType , typename IndexType , typename MixedValueType >

std::shared_ptr<gko::Array<IndexType *> > schwz::Communicate< ValueType, IndexType, MixedValueType >::comm_struct::global_get

The array containing the number of elements that each subdomain gets from the other.

For example. global_get[p][0] contains the overall number of elements to be received to subdomain p and global_put[p][i] contains the index of the solution vector to be received from subdomain p.
