     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.

     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
