8: * Does not implement attributes correctly.

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
