Release notes

  • MPI support:
    • Python-level: MPI-distributed NumPy arrays.
    • C-level: code generation for sub-domains, staggered grids, operators with coupled PDEs.
    • C-level: performance optimizations (e.g., computation-communication overlap).
  • Lazy evaluation of derivatives.
  • Revisited staggered grids API (now Dimension-based, previously mask-based).
  • Re-engineered clustering (which means smarter loop fusion/fission).
  • DSE: Improved aliases detection.
  • DLE: OpenMP nested parallelism; hierarchical loop blocking.
  • Auto-padding for Functions/TimeFunctions.
  • Improved data dependency analysis.
  • Smarter Operator auto-tuning.
  • New tutorials: Operator application, MPI, new propagators, custom stencils, and more.
  • Revisited benchmarking scripts.
  • Revisited examples, new models and propagators (e.g., visco-elastic).
  • Smarter continuous integration: now Travis sided by Azure Pipelines; dropped Jenkins.
  • Misc bug fixes.
  • Hundreds of tests added.
  • More sophisticated platform auto-detection.
  • Update in checkpointing (via PyRevolve) to significantly reduce memory consumption and overall runtimes. Not backward compatible.
  • Experimental support for lossy compression of checkpoints through PyRevolve + ZFP.
