NAME

distributor - data distribution table (rheolef-6.7)

SYNOPSYS

Used by "disarray"(1), "asr"(1) and "csr"(1). and such classes that distribute data as chunk.

IMPLEMENTATION

class distributor : public Vector<std::allocator<int>::size_type> {
public:
// typedefs:
typedef std::allocator<int>::size_type size_type; typedef Vector<size_type> _base; typedef _base::iterator iterator; typedef _base::const_iterator const_iterator; typedef int tag_type; typedef communicator communicator_type;
// constants:
static const size_type decide = size_type(-1);
// allocators/deallocators:
distributor( size_type dis_size = 0, const communicator_type& c = communicator_type(), size_type loc_size = decide);
distributor(const distributor&); ~distributor();
void resize( size_type dis_size = 0, const communicator_type& c = communicator_type(), size_type loc_size = decide);
// accessors:
const communicator_type& comm() const;
/// global and local sizes size_type dis_size () const;
/// current process id size_type process () const;
/// number of processes size_type n_process () const;
/// find iproc associated to a global index dis_i: CPU=log(nproc) size_type find_owner (size_type dis_i) const;
/// global index range and local size owned by ip-th process size_type first_index (size_type ip) const; size_type last_index (size_type ip) const; size_type size (size_type ip) const;
/// global index range and local size owned by current process size_type first_index () const; size_type last_index () const; size_type size () const;
/// true when dis_i in [first_index(ip):last_index(ip)[ bool is_owned (size_type dis_i, size_type ip) const;
// the same with ip=current process bool is_owned (size_type dis_i) const;
/// returns a new tag static tag_type get_new_tag();
// comparators:
bool operator== (const distributor&) const; bool operator!= (const distributor&) const; // data: protected: communicator_type _comm; };
