   Yes, in that situation you just need to call KSPSetInitalGuessNonzero() and 
then call KSPSolve again. Note that for GMRES and friends this will begin 
afresh by starting with a new Krylov space, it won't start from the partially 
built one.

   Be sure to reset KSPSetInitalGuessNonzero() for your next solve if that does 
require an initial guess of zero.

Hello,

Is it possible to run KSPSolve till the convergence (or not) , let the program 
do some work,

and then restart KSPSolve where it stopped ? (maybe with different tolerance or 
max iterations)


Thanks
