About:
Scotch is a software package for graph and mesh partitioning, graph clustering, and sparse matrix ordering. It provides a collection of programs and libraries for efficient parallel computing and scientific simulations. Its main value proposition is delivering high-performance static mapping and partitioning for large-scale computational problems.
Key Features:
  • Graph and mesh partitioning (e.g., k-way, bisection)
  • Sparse matrix ordering (e.g., AMD, MMD)
  • Graph coloring and coarsening
  • Distributed memory parallelism support (MPI)
  • Scotch library for integration into other applications
Use Cases:
  • Optimizing data distribution for parallel scientific simulations
  • Reducing fill-in in sparse linear solvers
  • Load balancing in high-performance computing (HPC) environments
Alternatives:
  • METIS – METIS is a widely used alternative for graph partitioning, but Scotch is often noted for its ability to handle weighted graphs and its distributed memory capabilities.
