  4:    This is a special set of bindings for uni-processor use of MPI by the PETSc library.

 10:    * Does not implement attributes correctly.

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

 17:   MPIUNI was developed with the aim of getting PETSc compiled, and
 18:   usable in the absence of MPI. This is the reason each function is
 19:   not documented.  The development strategy was - to make enough
 20:   changes to it so that PETSc source compiles without errors, and runs
 21:   in the uni-processor mode.

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

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

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

 40:   One of the goals with MPIUNI, is to avoid the function call overhead
 41:   of a regular MPI implementation. If this was not the case, we could
 42:   as well have used a regular implementation of MPI as they are
 43:   available on almost all machines. Hence most of the functions are
 44:   implemented as macros. One of the additional benefits we got from
 45:   MPIUNI is, we were able to use PETSc on machines where using a
 46:   proper implementation of MPI was painful (for eg NT).

 48:   Proper implementation of send/receive would involve writing a
 49:   function for each of them. Inside each of these functions, we have
 50:   to check if the send is to self or receive is from self, and then
 51:   doing the buffering accordingly (until the receive is called) - or
 52:   what if a nonblocking receive is called, do a copy etc.. Handling
 53:   the buffering aspects might be complicated enough, that in this
 54:   case, a proper implementation of MPI might as well be used. This is
 55:   the reason the send to self is not implemented in MPIUNI, and never
 56:   will be.
