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

I am trying to solver a sparse linear system (Ax=b) by PETSc. <BR> <BR>I noticed the parallel partitioning of the matrix is determined by PETSc at runtime by calling MatGetOwnerShipRange().<BR> <BR>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 : <A href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-2.3.3/src/ksp/ksp/examples/tutorials/ex2f.F.html" target=_blank>http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-2.3.3/src/ksp/ksp/examples/tutorials/ex2f.F.html</A> .<BR> <BR>Thanks.<BR> <BR> </body>
