Dear Thomas, 1. Do you compute on the same mesh? >
Yes, it is exactly the same mesh which is illustrated within your paper: 16384 cells (50115 DoFs). You can observe the same value also in the terminal output. I selected 4 global pre-refinement steps and 2 adaptive refinement cycles. > 2. do you compile in release mode or debug mode? > Release is faster. > Release mode. 3. Possibly you can optimize deal.Il with respect to the CPU etc. On my desktop computer at work, deal.II is 2 - 4 times slower than on my laptop for instance. I am using an Intel® Core™ i7-4770 CPU @ 3.40GHz × 8 processor. Hence, I assumed it would be even faster than your Intel(R) Core(TM) i5-3320M CPU@2.60 GHz machine. What MPI solver did you use? Intel with OpenMPI? Since I am using MPICH maybe there are some differences. I mean the difference in speed is not magic and should be based on the processor type or the settings of the solver. Maybe I should check how fast my MPI solver works outside of deal.II in order to see where the problem lies.
