[petsc-users] Implement new Krylov method within PETSc

[Barry Smith]

  Domenico,

    Please take a look at src/ksp/ksp/impls/cg/cg.c it contains comments at the top and in within the file on how one can copy the cg implementation and organize it for another Krylov method.

   Barry

   src/ksp/pc/impls/jacobi.c does a similar thing for preconditioners
