<p>Hi, PETSc developers<br></p><p>I am wondering what the difference is when iterative preconditioners (such as ILU, sparse approximation inverse and so on) are used in single and multiple rhs using KSPSolve().</p><p>In multiple rhs case, the preconditioners are made to each rhs? Thanks a lot.</p>
<p>Regards,</p><p>Yujie </p>
