devitocodes/devito: Devito-4.2
No full textGPU support
Added OpenACC 2.6 code generation support.
Added domain decomposition support for multi-node-multi-GPU via MPI and OpenACC.
Testing, CI/CD
Added testing with PGI compiler suite v19.10 on NVidia M80 GPU's.
Enhanced CI testing for OpenMP 5 offloading onto GPU's.
Enhanced CI testing for domain decomposition with MPI.
Performance optimizations
Wide range of performance optimizations to the Devito compiler to speed-up compile time (~2-5x speedup in compilation time).
Various low-level performance and memory optimizations (e.g. identifying and removing redundant computations).
DSL extensions
tools.Evaluable -> finite_differences.Evaluable
Dynamic FD shortcuts (i.e. u.dx(fd_order=2)). Supports FD order, x0 and side.
YASK and OPS backends
After a great deal of consideration, we have decided to drop support for YASK (https://01.org/yask) and OPS (https://github.com/OP-DSL/OPS) as Devito backends. While YASK and OPS have many desirable features, the software engineering overhead (person-effort) to maintain feature-complete support proved unsustainable. We would like to take this opportunity to thank Chuck Yount (YASK) and Istvan Reguly (OPS) for their collaboration on both software development and algorithm development, which has been of great benefit to Devito.
Tutorials and documentation
Revised FAQ - https://github.com/devitocodes/devito/wiki/FAQ
New Jupyter notebooks:
GPU tutorial.
PML boundary condition tutorial.
Normal Moveout (NMO) tutorial.
Revised viscoelastic example.
General updates
Added Developer Certificate of Origin to Devito contribution guidelines.
General improvements to documentation, examples and tutorials.
Several minor bug fixes.
Increased test coverage.
Improvements to test code coverage reporting.
Added PGI compiler support.
Added MPI support for the SubDomainSet feature.
Additional runtime warnings for inadequate problem specifications, e.g. stencil radius greater than rank-domain width.
Deprecate DEVITO_DLE, replaced by DEVITO_OPT.
Deprecate DEVITO_OPENMP, replaced by DEVITO_LANGUAGE.
