PETSc developers,
I am finally getting around to adding the DMLocalToLocalBegin/End routines
that I had mentioned several months ago. Looking at
DMGlobalToLocalBegin() in src/interface/dm/dm.c, I see that a little over
a year ago, Matt added the use of a default 'PetscSF' ("star forest") if
present to handle the global-to-local and local-to-global operations. I
am not familiar with PetscSF, but I assume that it should be possible to
use these somehow (maybe needing to add a little bit of code) for
local-to-local operations, since the communication pattern is the same as
for a global-to-local. Could someone who is familiar with PetscSF comment
on this?
Thanks,
Richard
