GPUs

  • Support for more Operators -- isotropic acoustic, TTI, elastic, viscoelastic, ...
  • Support for reductions
  • Fixed several bugs concerning code generation

DSL

  • Fixed minor bugs related to derivatives and finite-differences

MPI

  • Fixed several bugs arising in presence of SubDomains and/or SubDimensions
  • Fixed code generation in full mode (compute-communication overlap), when the same symbol (e.g. comm) was appearing twice in the signature of elemental functions

Documentation

  • Updated user API
  • Additional tutorials in the form of Jupyter notebooks (SymPy, DSL, SubDomains)

Benchmarking

  • A new mode exploiting the JIT_BACKDOOR mechanism was added
  • DevitoBench package merged into Devito

CI/CD:

  • Dropped Azure Pipelines and Travis; testing infrastructure moved to GitHub Actions
  • Added GPU testing
  • Added testing for osx
  • Auto-deployment on Pypi upon release

Compiler:

  • Improved architecture auto-detection
  • Refactored DLE as a sequence of "standard" compilation passes
  • Moved data dependence analysis to the Cluster level
  • Fixed data dependence analysis in some corner cases arising with SubDomains and/or SubDimensions
  • Moved interpolation to separate sub-package
  • Integrated profiling for the compilation pipeline
