OPS v2.0.1

Merge pull request #280 from OP-DSL/develop

Update version and improve documentation content

OPS v2.0.0

• New ops_translator (Primary / most important)

  • A new OPS code-generation engine (ops_translator) replaces the legacy translator.
  • Based on Python/Clang/Fparser/Jinja2 — produces improved C/C++/Fortran backends.
  • Enables broader target support and improved codegen quality (SYCL, HIP, CUDA, OpenMP offload, etc.).
  • All apps (including CloverLeaf, CloverLeaf_3D, wave_test, halfprecision) now use the new translator.
  • Migration notes: translator runtime requires updated Python dependencies (see ops_translator/requirements.txt), and generated output paths/filenames may differ from the legacy translator — review build scripts when upgrading.

• New back-end & language support:

  • SYCL targets and improved SYCL integration (CPU/GPU).
  • HIP support and HIP/CUDA codegen fixes.
  • Added/expanded OpenMP offload MPI backend.
  • Fortran offload support and improved Fortran templates.
  • OpenCL and OpenACC: no longer supported in this release. Legacy codegen
    and example targets referencing OpenCL/OpenACC remain in the tree for
    historical/reference purposes but are unmaintained. Users should migrate
    to SYCL, HIP, or OpenMP offload paths where possible.

• Precision & computation features:

  • Half-precision (float16) and mixed-precision support on GPUs and in code generation.
  • Multiblock mixed-precision halo-exchange fixes and enhancements.

• I/O, tooling & utilities:

  • HDF5 improvements including SoA output mode and robustness fixes for MPI HDF5 writes.
  • Energy and power measurement hooks (RAPL/powercap and GPU power capture).

• Bug fixes:

  • Fixed SYCL device selection (OPS_SYCL_DEVICE=gpu) crashing on empty device list.
  • Fixed Fortran I/O deadlock when using print/WRITE inside OpenMP parallel regions with Intel Fortran runtime.

• Build, CI and testing:

  • Numerous CMake and Makefile improvements (F90/CMake additions, device selection, build flags).
  • Added EXTRA_CLEAN_FILES support in Makefile.c_app for app-specific clean targets.
  • Added clean_all_apps.sh utility script.
  • CI/test additions and config changes (expanded tests, GPU_NUMBER config update).
  • Added test.sh for multiple C and Fortran apps.

• Documentation and developer experience:

  • Major documentation refreshes across the docs, developer guide updates and a new doc/quickstart.md.
  • Added example/test scripts for apps and updated tutorial timings.
  • Updated AUTHORS.
