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.
