In my system, deal_II.lib is about 400MB and deal_II.g.lib is almost 2GB.
Maybe the issue is somehow related to these reports:

The reason why the matrix in step-17 is not symmetric is actually

So why is it not 162x162?

can you show us what your "detailed.log" in the build directory looks like?
This file stores the configuration that is used for building deal.II.

Alexander,
I run step-8 and the system matrix is symmetry at least for the first
cycle. I attach the output txt of the system matrix in this reply. Thanks.

Thanks, Bruno.
I'm in no rush. I have other things I can work on too. The only other
difference I could find, other than the MPI/PETSc stuff, had to do
with solver_control() which should only effect # steps to solution.
I mainly brought it up because the results contrasted what I read in the

I'm not an expert in this field, but I assume it should be.
Can you please check if system matrix in step-8 (which was used to
implement step-17) is symmetric?

Hi Alexander,
Thank you for your explanation. I should have checked the symmetricity
first.
However, since the step-17 is isotropic linear elasticity problem, should
the system matrix be symmetry?
Thank you very much for your help and patience.

Shanglong

I saw it. I am just busy :-) I will try to take another look later.

Shanglong,
I can reproduce this behaviour, but this isn't a bug. I output the 162x162
system matrix at first cycle and as far as I can see it fails symmetry
check. You can see this already from first few non-zero entries:
(0,0) 1.3
(1,1) 1.3
(2,2) 1.3
(3,3) 1.3
(4,4) 1.3
(5,5
Thank to both of you for your time and answers.
Pr. Bangerth's solution works perfectly (although I guess I could and
should have figured it out by myself...)

Claire

Thank you. Yes, the first problem is due to a mistake in partitioning in
