- The MMMMPPPPIIII____SSSSccccaaaatttttttteeeerrrr routine sends data from one task to all other tasks in a
- group. This routine accepts the following parameters:
-
- _s_e_n_d_b_u_f Specifies the address of the send buffer (choice,
- significant only at root)
-
- _s_e_n_d_c_n_t Specifies the number of elements sent to each process
- (integer, significant only at root)
-
- _s_e_n_d_t_y_p_e Specifies the data type of the send buffer elements
- (significant only at root) (handle)
-
- _r_e_c_v_c_n_t Specifies the number of elements in the receive buffer
- (integer)
-
- _r_e_c_v_t_y_p_e Specifies the data type of the receive buffer elements
- (handle)
-
- _r_o_o_t Specifies the rank of the sending process (integer)
-
- _c_o_m_m Specifies the communicator (handle)
-
- _r_e_c_v_b_u_f Returns the address of the receive buffer (choice)
-
- _i_e_r_r_o_r Specifies the return code value for successful completion,
- which is in MPI_SUCCESS. MPI_SUCCESS is defined in the
- mmmmppppiiiiffff....hhhh file.
