anchor.diff:  which makes a grid with 3 polynomial coefficients, 100 cells in x, 100
   cells in y and 10 in z. If you compiled for OpenMP, you can set the
   number of threads with e.g. `export OMP_NUM_THREADS=4`.
  -[TIP]
  +____
   This is a
   benchmark program to benchmark various elemental functions the library
   is built on. Go ahead and vary the input parameters and see how your
   hardware performs. You can compile and run any other program that ends
   in `_t.cu` (test programs) or `_b.cu` (benchmark programs) in
   `feltor/inc/dg` in this way.

   Now, let us test the mpi setup
  -[TIP]
  +____
   You can of course skip this if you
   don't have mpi installed on your computer. If you intend to use the
   MPI backend, an implementation library of the mpi standard is required.
   Per default `mpic++` is used for compilation.

positive.code: * Change the Platform from x86 to x64.
  * Compile with `Ctrl + F5` then run the code
  
  [TIP]
  If you want to prevent the console from closing on program exit,
  set `Properties -> Linker -> System -> SubSystem -> Console (/SUBSYSTEM:CONSOLE)`
  in your Property Sheet.

  This guide discusses how to setup, test and benchmark the FELTOR library
  installation. Please read it before you proceed to the https://feltor-dev.github.io/tutorial/[online tutorial] to learn how to use the library in your own programs.
  We also present how to use the FELTOR software package,
  which requires additional external libraries to be installed on the system.
