Thanks, but I'd rather use Cray since only a small part of my code
relies on PETSc and, as suggested by the BW staff,
Cray-compiled code performs generally better on Cray system.

Hi,
I confirm that
-pc_type gamg -pc_mg_cycle_type v -pc_gamg_agg_nsmooths 1
produces the correct shift in PETSc 3.4.
So my problem is solved. I will upgrade to 3.4 in my productive
machine installation.
It is a Cray machine (Blue Waters). Assuming I want to use the Cray
compiler, which options should I use for ./configure
for the installation.
Or the Intel compiler or GCC. PETSc should run at similar speed with
any. IIRC, Cray recommends the Intel compiler on their machines with
Intel CPUs. There are examples in config/examples/.
