      lbmpy phasefield · 9cf1ac28
      Martin Bauer authored
      - step class for LB phasefield generic enough to work with 3-phase and
        N-phase models
      - cahn hilliard can either be solved by LBM or by finite differences
      - 3 phase model can be solved with rho phase or without

      Code generation for field serialization into buffers · 979ee93b
      João Victor Tozatti Risso authored and Martin Bauer's avatar Martin Bauer committed
      Concept: Generate code involving the (un)packing of fields (from)to linear
      (1D) arrays, i.e. (de)serialization of the field values for buffered
      communication.
      
      A linear index is generated for the buffer, by inferring the strides and
      variables of the loops over fields in the AST. In the CPU, this information is
      obtained through the makeLoopOverDomain function, in
      pystencils/transformations/transformations.py. On CUDA, the strides of
      the fields (excluding buffers) are combined with the indexing variables to infer
      the indexing of the buffer.
      
      What is supported:
          - code generation for both CPU and GPU
          - (un)packing of fields with all the memory layouts supported by
          pystencils
          - (un)packing slices of fields (from)into the buffer
          - (un)packing subsets of cell values from the fields (from)into the buffer
      
      Limitations:
      
      - assumes that only one buffer and one field are being operated within
      each kernel, however multiple equations involving the buffer and the
      field are supported.
      
      - (un)packing multiple cell values (from)into the buffer is supported,
      however it is limited to the fields with indexDimensions=1. The same
      applies to (un)packing subset of cell values of each cell.
      
      Changes in this commit:
      
      - add the FieldType enumeration to pystencils/field.py, to mark fields
      of various types. This is replaces and is a generalization of the
      isIndexedField boolean flag of the Field class. For now, the types
      supported are: generic, indexed and buffer fields.
      
      - add the fieldType property to the Field class, which indicates the
      type of the field. Modifications were also performed to the member
      functions of the Field class to add this property.
      
      - add resolveBufferAccesses function, which replaces the fields marked
      as buffers with the actual field access in the AST traversal.
      
      Miscelaneous changes:
      
      - add blockDim and gridDim variables as CUDA indexing variables.

      pystencils: fields can now contain structs · ec3faf51
      Martin Bauer authored
      - this extension is necessary for more generic boundary treatment
      - cells can now be structs, i.e. contain different data types
      - instead of having numeric index dimensions, one can use the index per cell to adress struct elements

      pystencils: Cleaned up type system · c8b455fe
      Martin Bauer authored
      - use data type class consistently instead of strings (in TypedSymbol, Field and jit module)
      - new datatype class is based on numpy types with additional specifier information (const and restrict)
      - translation between data type class and other modules (numpy, ctypes)

      Python 2.7 compatibility · cb05590d
      Michael Kuron authored and Martin Bauer's avatar Martin Bauer committed
      This commit makes the Python code backwards compatible down to Python 2.7. Previously it would only run on Python 3.5 and up.
      
      Problems fixed included:
      - `time.perf_counter()` doesn't exist
      - all classes need to be new-style
      - `functools.lru_cache` doesn't exist
      - only the last argument to a function call can be `*`-expanded
      - the `nonlocal` keyword doesn't exist
      - metaclasses are used with a different syntax
      - `yield from` doesn't exist
      - `tempdir.TemporaryDirectory` doesn't exist
      - iterators need a `next()` method

      pystencils: additional checks when calling kernel · 184489d0
      Martin Bauer authored
      - check that fixed size kernels are called with arrays of the correct size
      - checks that layout of compilation matches runtime layout
      - not allowed any more to mix fixed & and variable sized fields in a kernel
