PCBJacobiSetUseTrueLocal
Sets a flag to indicate that the block problem is associated with the linear system matrix instead of the default (where it is associated with the preconditioning matrix). That is, if the local system is solved iteratively then it iterates on the block from the matrix using the block from the preconditioner as the preconditioner for the local block.

-pc_bjacobi_truelocal -Activates PCBJacobiSetUseTrueLocal()
Notes
For the common case in which the preconditioning and
linearsystem matrices are identical, this routine is unnecessary.
