| In addition to missing the communicator arguments in the calls to MPI_Isend and MPI_Irecv, several of the MPI_Wait calls are missing the ierr argument (Page 44, lines 6 and 14). The call to MPI_COMM_RANK, on page 43, line 44, is also missing the ierr argument. Bill William Gropp Paul and Cynthia Saylor Professor of Computer Science University of Illinois Urbana-Champaign |
