      CUDA indexing: clip to maximum cuda block size · 1754ef27
      Martin Bauer authored
      - previous method did not work with kernels generated for walberla where
        block size changes are made at runtime
      - device query does not always work, since the compile system may have
        no GPU or not the same GPU
      -> max block size is passed as parameter and only optionally determined
         by a device query

      Improvements for GPU code generation · f504b40f
      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

      Bugfix: For certain MRT methods the CSE failed · 27a131fb
      Martin Bauer authored
      - replace_density_and_velocity simplification produced terms like
        0 * omega, because sympy's auto-eval is turned off
      - sympys CSE routine can apparently only handle evaluated terms
      - solution: evaluate multiplications with zero (i.e. replace them by 0)
