      [API] New interface for lattice model generation · 569cc1d8
      Martin Bauer authored
      - previously a LatticeBoltzmannMethod object was required to generate
        a lattice model for waLBerla
      - problem: output fields, smagorinsky, entropic additions are only done
        when coverting the method to a collision rule
      - the new interface now takes a collision rule instead of a LB method
      
      to adapt your app have a look at example usage in
      walberla/tests/lbm/codegen

      Improvements for GPU code generation · 5aa0445f
      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 · 4169807c
      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

      waLBerla codegeneration improved · 5e6fe078
      Martin Bauer authored
      - removed warnings from generated code
      - made generated code string deterministic, generating the same twice
        gives binary equally files now

      Pass field information (shape,stride) as single elements instead of arr · 9d8a7264
      Martin Bauer authored
      - small (length < 5) arrays with shape and stride information had to be
        memcpy'd to the GPU before every kernel call
      - instead of passing the information as arrays, the single elements are
        passed
      - leads to more function arguments, but simplifies GPU kernel calls
      
      -> changes in all backends required
