- The MMMMPPPPIIII____BBBBaaaarrrrrrrriiiieeeerrrr routine blocks until all processes have reached the
- routine at which the barrier is placed. It blocks the caller until all
- group members have called it; the call returns at any process only after
- all group members have entered the call. This routine accepts the
- following parameter:
-
- _c_o_m_m Specfies the communicator (handle)
-
- _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.
