! Module mpi_subs.f
! This module contains three main subroutines
! SUBROUTINE COLSUM
! SUBROUTINE SHARE0
! SUBROUTINE SHARE1
! SUBROUTINE SHARE2
! and auxiliary routines
! SUBROUTINE MPI_BCAST_CHAR
! SUBROUTINE MPI_BCAST_INT
! SUBROUTINE MPI_BCAST_INT2
! SUBROUTINE MPI_BCAST_REAL
! SUBROUTINE MPI_BCAST_CPLX
! COLSUM, SHARE1, and SHARE2 are used by DDSCAT to manage information
! in all the various processes when MPI is being used.
! MPI_BCAST_CHAR, MPI_BCAST_INT, MPI_BCAST_INT2, MPI_BCAST_REAL, and
! MPI_BCAST_CPLX are used here to provide "jackets" for MPI_BCAST for
! different variable types, to eliminate warning messages from fortran
! compilers.
!
! COLSUM, SHARE1, and SHARE2
! were originally written by Matthew Collinge,
! Princeton University Observatory, 2002.11.15
! Code has been modified to provide "jackets" for MPI_BCAST for
! different variable types, to eliminate warning messages from fortran
! compilers.
! history:
! 02.11.15 (BTD) Working version developed by Matthew Collinge
! 03.07.13 (BTD) cosmetic changes during preparation of official
! release of version 6.0
! 04.04.09 (BTD) modifications to introduce jacket routines
! MPI_BCAST_CHAR
! MPI_BCAST_INT
! MPI_BCAST_INT2
! MPI_BCAST_REAL
! MPI_BCAST_CPLX
! 08.05.01 (BTD) added MYID to arg list of SHARE0

! Subroutine SHARE1
! Given:
! Returns:
! This routine uses the MPI data type MPI_INTEGER2, which may
! not be supported in all implementations of MPI.
! The format of the call to MPI_BCAST is as follows:
!
! CALL MPI_BCAST(SENDPAR,NUMPAR,MPI_TYPEPAR,SOURCE_PROCESS,
! & MPI_COMM_WORLD,IERR)
!
! SENDPAR = information to communicate with other processes
! NUMPAR = number of units of information in SENDPAR
! MPI_TYPEPAR = MPI data type of SENDPAR
! SOURCE_PROCESS = identifier of the process sending the broadcast.
! Always 0 (master) in this code.
! MPI_COMM_WORLD = name of MPI communicator
! IERR = Error code. Not used by this code.
!
! collinge:
! what are the sizes of cbinflag and cnetflag?
! apparently 6, or maaaaybe 7 in fortran convention?
! I am not sure if this means of sending characters actually
! works or not. Needs to be tested.
