Distributed Computing through Combinatorial Topology: A Survey

As a distributed system executes (specifically in asynchronous models where processes can crash), the system loses information. In topological terms, the geometric representation of the system's state develops "holes." distributed computing through combinatorial topology pdf

The application of combinatorial topology to distributed computing involves representing the communication network of a distributed system as a simplicial complex. Each node in the network is represented as a vertex (0-simplex), and each pair of nodes that can communicate with each other is represented as an edge (1-simplex). Higher-dimensional simplices, such as triangles (2-simplices) and tetrahedra (3-simplices), can represent more complex communication patterns between nodes.

The Topological Proof

  1. Input Complex: Imagine the inputs as a high-dimensional solid shape (a simplex).
  2. The Map: An algorithm is essentially a function (a map) that takes the input shape and tries to morph it into the output shape.
  3. Connectivity: In a distributed system with failures, the communication pattern creates "holes." If a process crashes, the geometric shape representing the state gets torn.
  4. Continuity: A valid wait-free algorithm must be represented by a continuous map. You cannot tear the fabric of the space.
