[petsc-users] how to obtain the vector value at the other processor.

[Barry Smith]

  If you wish all the entries on one or all processes then see

http://www.mcs.anl.gov/petsc/documentation/faq.html#mpi-vec-to-seq-vec or http://www.mcs.anl.gov/petsc/documentation/faq.html#mpi-vec-to-mpi-vec  

if you want a subset of entries from other processes on each process then you need to see the manual page for VecScatterCreate().
