alternatively,
you could run the same configuration on a workstation and copy the tmp/src
and tmp/unpack to your cluster.
Maybe you need the developer_mode as given by the last line of the
config file as well - I'm not sure on that since I never run it without
git access.

No, I don't think so. You should get very close performance. On top of
that, deal.II does not support T
Dear Bruno,
Thanks, that definitely answers my questions.
I would have a final slightly related question.

setup by going from AztecOO to the Tpetra or Belos stack?
I guess that the best parallel performance increase I coul

Yes, that's right. You won't get any speedup using OpenMP with
AztecOO, you need to switch to the Tpetra stack and Belos to use

Hi Jean,
Minor unrelated note to your snippet of manually written L2 norm: have a
look at

which has plenty of template wrappers for MPI functions that can make life
much much easier, including sending objects that

Bonjour Jean-Paul,
First, thank you for your detailed answer, it is immensively appreciated.
1. You are right, the documentation does not suggest using or not using
openmp with Trilinos. I was just skeptical, because if you look here

there is
Dear Muhammad,
This is not really a deal.II related question, but I’ll try to help you anyway.
CMake is telling you that you don’t have a Fortran compiler installed, so you
should install one. You should be able to do this with “sudo apt install

I hope that this help you.
Best,

Can you please indicate where you read this? I’m looking at our documentation
for interfacing to external libraries, i.e.
