Hi all,
thanks for the many tips and suggestions, I really appreciate you spending
your time and effort helping me out!
I set up valgrind and kcachegrind, which I found exceptionally easy and can
get started now - perfect!
In case anyone reads this in the future, I had to use "mpirun -n 4
Dear Richard,

which parts of the code take time apart from the (already detailed) TimerOutput.
Use valgrind's callgrind tool. The
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
