      Implemented an improved version of the communication for periodic BC · 4816bfae
      Markus Holzer authored and Martin Bauer's avatar Martin Bauer committed
      The communication of the ghost layers used to communicate just all
      values in between one time step to make sure that everything is correct.
      Furthermore the communication was only valid for pull stream steps.
      The improved communication distinguishes automatically between pull and
      push and communicates only values which are needed. With this improvement
      it was possible to implement the EsoTwist streaming scheme.

      Improvements for GPU code generation · 9748ab43
      Martin Bauer authored
      - turned on restrict keyword by default (makes large difference on GPUs)
      - smarter block indexing: changing block size depending on domain size
        Example: previously there where (1,1,1) blocks when requested
        block size was (64, 1, 1) and domain size (1, 512, 512), now the
        block size is changed automatically to (1, 64, 1) in this case
      - added __lauch_bounds__ to kernels to allow better optimizations from
        the CUDA compiler

      Random number generation support for pystencils · b789f010
      Martin Bauer authored
      - counter-based philox RNG: counter/key is filled with cell coordinate
        and optional external parameters like block position and time step
      - works on CPU and GPU - on CPU only for non-vectorized versions
      
      - introduced more flexible "CustomCodeNode" that can inject
        backend-specific hand-written code

      More flexible boundary handling · 160123f5
      Martin Bauer authored
      boundary conditions can specify how the index list should be built:
      - list coordinates of domain or boundary cells (previous always inner)
      - list all links or only the first link
