I am trying to solver a sparse linear system (Ax=b) by PETSc.
I noticed the parallel partitioning of the matrix is determined by PETSc at
runtime by calling MatGetOwnerShipRange().
I am wondering if the right hand side vector (b) should be partitioned by
Calling VecGetOwnerShipRange(), Since I didn't see it is called in example code
of ex2f.F on webpage of :
http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-2.3.3/src/ksp/ksp/examples/tutorials/ex2f.F.html
.
Thanks.
