Have you give a look to VecLoadIntoVector() ? For use it, you have to
previously create the vector with the desired distribution (or get it
from DA's), and then the values will be read and used to fill your
vector... Of couse, you have to get shure that the ordering of indices
is the same (and I believe it should be the 'natural' DA ordering),
this is specially important if you run your problem with different
number of processes.
