  Inter-communicator Extensions to MPI in the MPIX (MPI eXtension) Library
  by Skjellum, Doss, Viswanathan

  Abstract

  MPI is the new standard for multicomputer and cluster message
  passing introduced by the Message-Passing Interface Forum (MPIF) in
  April 1994.  This paper describes the current inter-communicator
  interface found in MPI and the reasons for its current design.  We
  also motivate the need for additional inter-communicator operations
  and introduce the extensions we have included in MPIX (MPI eXtension
  Library), a library of extensions to MPI that we are currently
  developing.

  Inter-communicators may be used for a variety of purposes such as in
  client/server applications (i.e., I/O and graphics servers) and for
  process management in dynamic process environments and
  multi-protocol implementations; MPI's definitions are unnecessarily
  restrictive, so we extend them here.  We discuss the
  inter-communicator collective operations defined in MPIX and
  illustrate their use.  We also discuss additional inter-communicator
  construction routines not in the original MPI interface, but that
  are provided in MPIX.  Our final contribution is a strategy for
  extending virtual topologies to support inter-communicators
  with the MPIX inter-communicator library.
