[petsc-users] Should the vactor be partitioned?

[Peter Wang]

Thanks. One more question.
 
Should the vactor (b) be assembled after calling VecSetValues() ?

Subject: [petsc-users] Should the vactor be partitioned?




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.
