veros - v1.3.2
Changes
- New setting
biharmonic_friction_cosPowerto scale biharmonic friction with latitude - New runtime setting
monitor_streamfunction_residualto switch off convergence checks in PETSc solver - Restart files are never written in the first iteration

veros - v1.3.0
This is a huge release with many breaking changes.
Setups written for previous versions of Veros will not be compatible with this version.
New versioning scheme
- We have decided to add +1 to the Veros version. Veros has been at a stage where it is mature enough for scientific applications for a while, and we feel that a version
1.x.xreflects that better than0.x.x.
Major changes
- A new command line interface to execute Veros setups:
$ veros run mysetup.py - Bohrium is now replaced with JAX. JAX is easier to install and provides better performance on CPU and GPU.
- Overhauled the internal data model. All model state is now encapsulated in a
VerosStateobject that can be passed around and inspected. - Major performance increases on GPU.
- The PETSc linear solver now works on GPUs.
- Explicit support for custom variables and dimensions.
- Many bug fixes and quality-of-life improvements.
- Asset files are now in JSON format.
Internal changes
- Enforcing of a code formatting standard via
flake8andblack. - Hand-written TDMA kernels (CUDA kernel by @sefrin).
- A more robust testing suite.
- Better modularity of diagnostics and model restarts.

veros - v0.2.2
Changes
- Assets are now downloaded the first time they are accesses (instead of during import)
- Dependencies are pinned by default
- Streamfunction solver uses a new ILU preconditioner that shows very good performance. PyAMG support has been dropped.
- Linear solver can now be chosen via the
VEROS_LINEAR_SOLVERenvironment variable. - Wind stress (
surface_taux,surface_tauy) now has the correct units in output files. global_4degsetup now has an ITF (Indonesian Throughflow).- Fixed critical bugs related to wind stress in
accandglobal_flexiblesetups.

veros - v0.2.1
Changes
- A new plugin system that supports external development on Veros
- Diagnostics now have their own log level to make sure output is displayed in most cases
- Veros now supports system-wide setup folders that can be discovered by
veros copy-setup - Fixed bugs in overturning diagnostic
- Potential density is now computed as a model variable
- Fixed missing attributes on netCDF outputs
- Tweaked documentation
- Python

veros - v0.2.0
This is a huge release with many exciting changes!
This release is not backwards-compatible. Setups created with v0.1.x will have to be rewritten to work with this version.
Changes
- Veros now fully supports distributed architectures through MPI, for both NumPy and Bohrium backends. If you have MPI installed, just run something like
bash
$ mpirun -n 4 python mysetup.py -n 2 2
to get started.
A new realistic flexible resolution setup (
global_flexible) that automatically adapts to the chosen resolution. Just choose a resolution and time step and that's it! Also comes with automatic removal of marginal seas.Better output and logging capabilities: terminal colors, a progress bar and throughput indicator, more verbosity options.
A re-implementation of the island routines, which are now faster and more stable.
A fully distributed Poisson solver via PETSc that is over 10x faster than PyOM's solver.
netCDF output via HDF5, so libnetcdf is not a dependency anymore.
The old
Verosbase class is now separated intoVerosSetup(containing all setup-specific logic) andVerosState(holding the model settings and variables).Global runtime settings:
```python from veros import runtime_settings as rs
rs.backend = 'bohrium' ```
Polished documentation.
Various code quality improvements and polish.
Removed features
Dropped Python 2 support.
Removed Eady setup.
Removed
logfileargument.

veros - v0.1.1
Veros on PyPI
Veros is now installable via pip! This allows you to get started with Veros in lightning speed:
bash
$ pip install veros
$ veros copy-setup --to /tmp
$ python /tmp/acc/acc.py
Other changes
- Command line interfaces are now based on
clickinstead ofargparse. Unless explicitly told, Veros does not consume any arguments from the command line any more. In setups meant to be run interactively, you can add the following to parse command line arguments:
```python @veros.tools.cli def run(args, *kwargs): simulation = MySetup(args, *kwargs) simulation.setup() simulation.run()
if name == "main": run() ```
Setup assets (i.e., external binary files required to run the standard setups) are now downloaded on demand to
$HOME/.veros, or to wherever the environment variableVEROS_ASSET_DIRpointed when Veros was imported.Git LFS is not required anymore.
Veros is now licensed under a MIT license.

veros - v0.1.0
The first official release of Veros!
All core routines in this version are more or less direct (vectorized) translations of their respective pyOM 2.1.0 counterpart.
The code is optimized for use with NumPy or Bohrium, using either the OpenMP or OpenCL backend.
Supports both Python 2.7 and 3.x, but you might run into issues with Bohrium on Python 3.x.
