 11: /*
 12:   The following info is a response to one of the petsc-maint questions
 13:   regarding MPIUNI.

 15:   MPIUNI was developed with the aim of getting PETSc compiled, and
 16:   usable in the absence of a full MPI implementation. With this, we
 17:   were able to provide PETSc on Windows, Windows64 even before any MPI
 18:   implementation was available on these platforms. [Or with certain
 19:   compilers - like borland, that do not have a usable MPI
 20:   implementation]

 22:   However - providing a seqential, standards compliant MPI
 23:   implementation is *not* the goal of MPIUNI. The development strategy
 24:   was - to make enough changes to it so that PETSc sources, examples
 25:   compile without errors, and runs in the uni-processor mode. This is
 26:   the reason each function is not documented.

 28:   PETSc usage of MPIUNI is primarily from C. However a minimal fortran
 29:   interface is also provided - to get PETSc fortran examples with a
 30:   few MPI calls working.

 32:   One of the optimzation with MPIUNI, is to avoid the function call
 33:   overhead, when possible. Hence most of the C functions are
 34:   implemented as macros. However the function calls cannot be avoided
 35:   with fortran usage.

 37:   Most PETSc objects have both sequential and parallel
 38:   implementations, which are separate. For eg: We have two types of
 39:   sparse matrix storage formats - SeqAIJ, and MPIAIJ. Some MPI
 40:   routines are used in the Seq part, but most of them are used in the
 41:   MPI part. The send/receive calls can be found mostly in the MPI
 42:   part.

 44:   When MPIUNI is used, only the Seq version of the PETSc objects are
 45:   used, even though the MPI variant of the objects are compiled. Since
 46:   there are no send/receive calls in the Seq variant, PETSc works fine
 47:   with MPIUNI in seq mode.

 49:   The reason some send/receive functions are defined to abort(), is to
 50:   detect sections of code that use send/receive functions, and gets
 51:   executed in the sequential mode. (which shouldn't happen in case of
 52:   PETSc).

 54:   Proper implementation of send/receive would involve writing a
 55:   function for each of them. Inside each of these functions, we have
 56:   to check if the send is to self or receive is from self, and then
 57:   doing the buffering accordingly (until the receive is called) - or
 58:   what if a nonblocking receive is called, do a copy etc.. Handling
 59:   the buffering aspects might be complicated enough, that in this
 60:   case, a proper implementation of MPI might as well be used. This is
 61:   the reason the send to self is not implemented in MPIUNI, and never
 62:   will be.
 63:   
 64:   Proper implementations of MPI [for eg: MPICH & OpenMPI] are
 65:   available for most machines. When these packages are available, Its
 66:   generally preferable to use one of them instead of MPIUNI - even if
 67:   the user is using PETSc sequentially.

 69:     - MPIUNI does not support all MPI functions [or functionality].
 70:     Hence it might not work with external packages or user code that
 71:     might have MPI calls in it.

 73:     - MPIUNI is not a standards compliant implementation for np=1.
 74:     For eg: if the user code has send/recv to self, then it will
 75:     abort. [Similar issues with a number of other MPI functionality]
 76:     However MPICH & OpenMPI are the correct implementations of MPI
 77:     standard for np=1.

 79:     - When user code uses multiple MPI based packages that have their
 80:     own *internal* stubs equivalent to MPIUNI - in sequential mode,
 81:     invariably these multiple implementations of MPI for np=1 conflict
 82:     with each other. The correct thing to do is: make all such
 83:     packages use the *same* MPI implementation for np=1. MPICH/OpenMPI
 84:     satisfy this requirement correctly [and hence the correct choice].

 86:     - Using MPICH/OpenMPI sequentially should have minimal
 87:     disadvantages. [for eg: these binaries can be run without
 88:     mpirun/mpiexec as ./executable, without requiring any extra
 89:     configurations for ssh/rsh/daemons etc..]. This should not be a
 90:     reason to avoid these packages for sequential use.

 92:     Instructions for building standalone MPIUNI [for eg: linux/gcc+gfortran]:
 93:     - extract include/mpiuni/mpi.h,mpif.f, src/sys/mpiuni/mpi.c from PETSc
 94:     - remove reference to petscconf.h from mpi.h
 95:     - gcc -c mpi.c -DPETSC_HAVE_STDLIB_H -DPETSC_HAVE_FORTRAN_UNDERSCORE
 96:     - ar cr libmpiuni.a mpi.o
