Project Structure

DaCe is divided into the following subfolders:

• Interfaces and entry points:

  • frontend: Different language frontends that can be converted to SDFGs:

    • frontend/python: Python frontend. See Writing DaCe Programs in Python and DaCe Python Frontend

    • frontend/common: Common utilities for multiple frontends

  • cli: Command-Line Utilities that can view, compile, and profile SDFGs

• Intermediate representation:

  • sdfg: The SDFG Builder API

    • sdfg/graph.py: General graph API for manipulation and traversal of nodes, edges, and their contents

    • sdfg/{nodes, scope, sdfg, state}.py: Interfaces for specific SDFG components

    • sdfg/validation.py: Functions that validate the correctness of SDFGs. See Graph Validation

    • sdfg/propagation.py: Memlet Propagation

  • dtypes.py: Basic enumerations and data types that are used in DaCe

  • data.py: Definitions for usage and creation of Data Containers and Access Nodes

  • memlet.py: Definition of a Memlet

  • subsets.py: Subset types used in memlets (e.g., Range)

  • symbolic.py: Symbolic types, expressions, conversion, and analysis functions. See Symbols and symbolic

• Optimization and transformation:

  • transformation: Transformation classes and helpers. See Pattern-Matching and Subgraph Transformations

    • transformations/{dataflow, interstate, subgraph}: Built-in DaCe transformations

  • optimization: Automatic SDFG tuning interfaces

• Backends:

  • codegen: Code Generation

  • runtime: Thin runtime that supports DaCe-generated code. See C++ Runtime Headers

  • sourcemap.py: Source mapping capabilities that maps frontend code <–> SDFG <–> generated code

• Library nodes and libraries (See libraries):

  • library.py: Library interface

  • libraries: Built-in libraries

• Configuration

  • config.py: Configuration-related classes. See Configuring DaCe

  • config_schema.yml: Configuration specification file (schema) with defaults and documentation

• Miscellaneous

  • serialize.py and registry.py: Functionality that supports serialization and extensibility. See Properties and Serialization

  • external: Git submodules containing necessary external projects

  • viewer: Contains infrastructure for rendering SDFGs. Used in Jupyter notebooks and in sdfv - SDFG Viewer
