Checkpoint in PETSc

[Santolo Felaco]

Hi, I have to implement the checkpoint of function KSPSolve_CG.
I have many problem.

1- Can I to duplicate the KSP object? Can I send the KSP objcet to
checkpoint process?
2 - I'm using FT-MPI, in case of fault can I set (do not recreate) the new
communicator to object of alive process?

Thanks
