[petsc-users] Multigrid iterations for different versions of Petsc

Hi,
Again me with multigrid. Sorry for the annoyance, but I am a bit worried about
my multigrid solver: I still can't figure out where (if something) my code is
doing wrong.
I post the details of a run with my local machine and Petsc 3.5 compared with
the runs done with Petsc 3.4.3 on a cluster (the most recent version
available).
The problem is that the run in the cluster (3.4.3) does twice many iteration
per krylow solver (as the local 3.5) and goes even worse when increasing the
mesh. Also, while on my local machine I get 7 iterations (which is quite
nice), on the cluster I get 14 iteration, which is not what I expect from
multigrid.
Are there been any changes on the MG solver that can influence the behaviour of
the solver?
http://www.mcs.anl.gov/petsc/documentation/changes/35.html
seems not to include anything relevant.
Everything is the same: outer iteration with gmres, lu as coarse solver etc
(all default), I just adapted the APIs. Thus I'd expect more or less the same
result.
Best,
Filippo
I attach the profiles.
