1# Changes: Development 2 3% STYLE GUIDELINES: 4% * Capitalize sentences 5% * Use imperative, e.g., Add, Improve, Change, etc. 6% * Don't use a period (.) at the end of entries 7% * If multiple sentences are needed, use a period or semicolon to divide sentences, but not at the end of the final sentence 8 9```{rubric} General: 10``` 11 12```{rubric} Configure/Build: 13``` 14 15- Make `SYCL` a `devicePackage`, i.e., builds `--with-sycl` now have `PETSC_HAVE_DEVICE` defined 16- Add the option `--with-devicelanguage` to compile `PetscDevice` code using either a C or C++ compiler 17 18```{rubric} Sys: 19``` 20 21```{rubric} Event Logging: 22``` 23 24- Add two approaches for GPU energy monitoring: `-log_view_gpu_energy` and `-log_view_gpu_energy_meter` 25- Add API `PetscLogGpuEnergy()`, `PetscLogGpuEnergyMeter()`, `PetscLogGpuEnergyMeterBegin()` and `PetscLogGpuEnergyMeterEnd()` for GPU energy monitoring 26 27```{rubric} PetscViewer: 28``` 29 30```{rubric} PetscDraw: 31``` 32 33```{rubric} AO: 34``` 35 36```{rubric} IS: 37``` 38 39```{rubric} VecScatter / PetscSF: 40``` 41 42```{rubric} PF: 43``` 44 45```{rubric} Vec: 46``` 47 48```{rubric} PetscSection: 49``` 50 51```{rubric} PetscPartitioner: 52``` 53 54```{rubric} Mat: 55``` 56 57```{rubric} MatCoarsen: 58``` 59 60```{rubric} PC: 61``` 62 63- Add multi-precision support for MUMPS.
