Hi,
I've used the scalasca tool suite for profiling:
https://www.scalasca.org/scalasca/about/about.html
which use score-p for measuring and the cube gui for visualizing the
results:

Dear Richard,
I have used valgrind's callgrind tool extensively in the past and it works
quite well.
It seems Intel VTune is free now. I have used it a lot in the last two
months to optimize our code and I have found it work very, very well. We
managed to improve some functions tremendously
Richard,

Hi Martin,
Sorry for the slow response - I have been on vacation.
If you save a source file with a new name then you will need to update your
CMakeLists.txt file - it doesn't know what you intend to do with the new file.
I recommend reading through
All,
this is also the time to point out, as we do for every release, how many many
people have contributed to this release! The release paper at
https://www.dealii.org/deal93-preprint.pdf
has 17 authors, all of whom have contributed in many different and significant
ways to this release.
Hello everyone!
This is deal.II newsletter #176.
It automatically reports recently merged features and discussions about the
deal.II finite element library.

Richard,
a) which (free) profiling tools can you recommend? I watched the video lecture
of Wolfgang about that topic, but was looking for more opinions! I want to see
which parts of the code take time apart from the (already detailed) TimerOutput.

Version 9.3.0 of deal.II, the object-oriented finite element library awarded the
J. H. Wilkinson Prize for Numerical Software, has been released. It is
available for free under an Open Source license from the deal.II homepage at

I just wanted to add that I use CLion for C++ programming. I have been
developing codes (and linking to deal.ii among other libraries) in CLion
for 3 years now. Given that the entry point in CLion is a CMakeList file,
it was quite easy for me to load deal.ii examples and

Peter,
Thanks very much for taking time and providing the resources. I will go
through them and get back if I have any more questions.

Dear all,
I spent quite some time on our in-house CFD and FSI solvers, which are
matrix-based and use deal.II, MPI and AMG packages of Trilinos and PETSc,
all of which are so wonderfully accessible even for engineers like me. My
computations now focused on problems with relatively small DoF
Hi,
I recently started using VS code with deal.ii. I found it very easy to work
with, especially when you have a wsl installation.
All you need to do is follow the instructions on these pages -

Hi Luca,
thanks for clarifying. Still not succeeded, see below.
1. opened a Rosetta terminal
2. source /Applications/deal.II.app/Contents/MacOS/dealii.conf

Actually, not exactly. The instructions are i the screen shot.
Open a Rosetta terminal, and then source the conf file, i.e.
./Appl/dealii.conf
The command you called opens a normal terminal, and then sources the conf file.

Luca,
this is what I have done, if I got what you meant:
1. opened a Rosetta terminal
2. /Applications/deal.II.app/Contents/MacOS/dealii-terminal

Can you open a Rosetta terminal and follow the instructions to parse deal.ii
init files? I think it is just the fact that you are not running under Rosetta,
but cannot confirm...

Hi Vachan,
I don't think you need to use RPE plane. My guess is that you can use
VectorTools::point_values(), which internally uses PRE (see
https://github.com/dealii/dealii/blob/e413cbf8ac77606cf4a04e1e2fa75232c08533b4/include/deal.II/numerics/vector_tools_evaluate.h#L230-L343).
