• exbsend.f
  Last modified 21:24:00, 26 Oct 1994 - 1K - Fortran
  Exchange data with neighbors for a 1-d decomposition of a 2-d domain, using send and receive up, then down. Uses buffered sends.
• exchng1.f
  Last modified 21:24:00, 26 Oct 1994 - 1K - Fortran
  Version of exbsend.f that uses the MPI_SENDRECV call.
• exchng1nb.f
  Last modified 21:24:00, 26 Oct 1994 - 1K - Fortran
  Version of exbsend.f that used nonblocking send and receive (MPI_ISEND, MPI_IRECV, and MPI_WAITALL).
• exchng2.f
  Last modified 21:48:00, 20 Jun 1995 - 1.3K - Fortran
  Exchange data with neighbors for a 2-d decomposition of a 2-d domain, using MPI_SENDRECV and a "strided" data-type.
• expair1d.f
  Last modified 21:24:00, 26 Oct 1994 - 1.3K - Fortran
  Version of exbsend.f that uses "pair" blocking sends and receives.
• exsandr1d.f
  Last modified 21:24:00, 26 Oct 1994 - 1K - Fortran
  Version of exbsend.f that uses MPI_SEND instead of MPI_BSEND.
• exsync1d.f
  Last modified 21:24:00, 26 Oct 1994 - 1K - Fortran
  Version of exbsend.f that uses MPI_SSEND instead of MPI_BSEND. Used to show behavior of MPI_SEND when no internal buffering is provided.
• fndnbr2d.f
  Last modified 21:24:00, 26 Oct 1994 - 1K - Fortran
  Compute the neighbors and decomposition for a 2-d decomposition of a 2-d domain.
• mpirun

• nbexchng.f
  Last modified 21:24:00, 26 Oct 1994 - 1.1K - Fortran
  Non-blocking exchange. This is similar to exchng1nb.f, except that the MPI_WAITALL is called depending on an input argument (allowing the communication to overlap computation).
