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 MPI. This is the reason each function is
17: not documented. The development strategy was - to make enough
18: changes to it so that PETSc source compiles without errors, and runs
19: in the uni-processor mode.
21: Most PETSc objects have both sequential and parallel
22: implementations, which are separate. For eg: We have two types of
23: sparse matrix storage formats - SeqAIJ, and MPIAIJ. Some MPI
24: routines are used in the Seq part, but most of them are used in the
25: MPI part. The send/receive calls can be found mostly in the MPI
26: part.
28: When MPIUNI is used, only the Seq version of the PETSc objects are
29: used, even though the MPI variant of the objects are compiled. Since
30: there are no send/receive calls in the Seq variant, PETSc works fine
31: with MPIUNI in seq mode.
33: The reason some send/receive functions are defined to abort(), is to
34: detect sections of code that use send/receive functions, and gets
35: executed in the sequential mode. (which shouldn't happen in case of
36: PETSc).
38: One of the goals with MPIUNI, is to avoid the function call overhead
39: of a regular MPI implementation. If this was not the case, we could
40: as well have used a regular implementation of MPI as they are
41: available on almost all machines. Hence most of the functions are
42: implemented as macros. One of the additional benefits we got from
43: MPIUNI is, we were able to use PETSc on machines where using a
44: proper implementation of MPI was painful (for eg NT).
46: Proper implementation of send/receive would involve writing a
47: function for each of them. Inside each of these functions, we have
48: to check if the send is to self or receive is from self, and then
49: doing the buffering accordingly (until the receive is called) - or
50: what if a nonblocking receive is called, do a copy etc.. Handling
51: the buffering aspects might be complicated enough, that in this
52: case, a proper implementation of MPI might as well be used. This is
53: the reason the send to self is not implemented in MPIUNI, and never
54: will be.
