Hi,
I just started to use deal.II for my Ph.D. recently, so I am still not very
familiar with the deal.II structure.
That is why I am learning by using Prof. Bangerth's amazing video lectures,
which is why I would like now to run step-40 using MPI and p4est.
I have the following problem:
step-40 works perfectly, if I use mpirun with only 1 core, namely -np 1.
But for 8 cores it gets stuck at cycle 6 without any message. It runs
forever.
I assume it is related to PETSC since I am using version 3.7.4 and
according to the deal.II Readme:
*Note:* The most recent version of PETSc that has been reported to be
compatible with deal.II is version 3.6.0. If you use a later version than
this and encounter problems, let us know.
Hence, I liked to let you know about this problem with PETSC 3.7.4.
Unfortunately, using PETSC 3.6.x results in a compilation error with my
current Intel MPI library:
...

I would appreciate it, if anyone could give me a hint on how to solve this
dilemma :)
Kind regards,
