[petsc-users] Multi-preconditioned Krylov

[Karin&NiKo]

Dear PETSc team,

I would like to experiment multi-preconditioned Krylov methods, as
presented in the paper or Bridson and Greif (
https://www.cs.ubc.ca/~rbridson/mpcg/) and more specifically in a context
of DD like in the paper of Spillane (
https://hal.archives-ouvertes.fr/hal-01170059/document) or Gosselet (
https://hal.archives-ouvertes.fr/hal-01056928/document).

It seems to me this is not a basically supported feature of PETSc.

My question :
Is there a way of doing it by playing with the runtime options of PETSc or
do I have to implement it in the core of the KSP object? If so, what would
be the correct design?

Thanks,
Nicolas
