Since the best way to remember something is to understand the reasons behind it, make sure you go through the style guide at least once, paying special attention to the discussions in the _Pros_, _Cons_, and _Decision_ subsections. + +We deviate from the [Google Python Style Guide][google-style-guide] only in the following points: + +- We use [`ruff-linter`][ruff-linter] instead of [`pylint`][pylint]. +- We use [`ruff-formatter`][ruff-formatter] for source code and imports formatting, which may work differently than indicated by the guidelines in section [_3. Python Style Rules_](https://google.github.io/styleguide/pyguide.html#3-python-style-rules). For example, maximum line length is set to 100 instead of 79 (although docstring lines should still be limited to 79). +- According to subsection [_2.19 Power Features_](https://google.github.io/styleguide/pyguide.html#219-power-features), direct use of _power features_ (e.g. custom metaclasses, import hacks, reflection) should be avoided, but standard library classes that internally use these power features are accepted. Following the same spirit, we allow the use of power features in infrastructure code with similar functionality and scope as the Python standard library. +- According to subsection [_3.19.12 Imports For Typing_](https://google.github.io/styleguide/pyguide.html#31912-imports-for-typing), symbols from `typing` and `collections.abc` modules used in type annotations _"can be imported directly to keep common annotations concise and match standard typing practices"_. Following the same spirit, we allow symbols to be imported directly from third-party or internal modules when they only contain a collection of frequently used typying definitions. + +### Common questions + +- `pass` vs `...` (`Ellipsis`) + + `pass` is the _no-op_ statement in Python and `...` is a literal value (called _Ellipsis_) introduced for slicing collections of unknown number of dimensions. Although they are very different in nature, both of them are used in places where a statement is required purely for syntactic reasons, and there is not yet a clear standard practice in the community about when to use one or the other. We decided to align with the common pattern of using `...` in the body of empty function definitions working as placeholders for actual implementations defined somewhere else (e.g. type stubs, abstract methods and methods appearing in `Protocol` classes) and `pass` in any other place where its usage is mixed with actual statements. + + ```python + # Correct use of `...` as the empty body of an abstract method + class AbstractFoo: + @abstractmethod + def bar(self) -> Bar: + ... + + # Correct use of `pass` when mixed with other statements + try: + resource.load(id=42) + except ResourceException: + pass + ``` + +### Error messages + +Error messages should be written as sentences, starting with a capital letter and ending with a period (avoid exclamation marks). Try to be informative without being verbose. Code objects such as 'ClassNames' and 'function_names' should be enclosed in single quotes, and so should string values used for message interpolation. + +Examples: + +```python +raise ValueError(f"Invalid argument 'dimension': should be of type 'Dimension', got '{dimension.type}'.") +``` + +Interpolated integer values do not need double quotes, if they are indicating an amount. Example: + +```python +raise ValueError(f"Invalid number of arguments: expected 3 arguments, got {len(args)}.") +``` + +The double quotes can also be dropped when presenting a sequence of values. In this case the message should be rephrased so the sequence is separated from the text by a colon ':'. + +```python +raise ValueError(f"unexpected keyword arguments: {', '.join(set(kwarg_names) - set(expected_kwarg_names))}.") +``` + +The message should be kept to one sentence if reasonably possible. Ideally the sentence should be kept short and avoid unnecessary words. Examples: + +```python +# too many sentences +raise ValueError(f"Received an unexpected number of arguments. Should receive 5 arguments, but got {len(args)}. Please provide the correct number of arguments.") +# better +raise ValueError(f"Wrong number of arguments: expected 5, got {len(args)}.") + +# less extreme +raise TypeError(f"Wrong argument type. Can only accept 'int's, got '{type(arg)}' instead.") +# but can still be improved +raise TypeError(f"Wrong argument type: 'int' expected, got '{type(arg)}'") +``` + +The terseness vs. helpfulness tradeoff should be more in favor of terseness for internal error messages and more in favor of helpfulness for `DSLError` and it's subclassses, where additional sentences are encouraged if they point out likely hidden sources of the problem or common fixes. + +### Docstrings + +TODO: update to autodoc2 + +We generate the API documentation automatically from the docstrings using [Sphinx][sphinx] and some extensions such as [Sphinx-autodoc][sphinx-autodoc] and [Sphinx-napoleon][sphinx-napoleon]. These follow the Google Python Style Guide docstring conventions to automatically format the generated documentation. A complete overview can be found here: [Example Google Style Python Docstrings](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html#example-google). + +Sphinx supports the [reStructuredText][sphinx-rest] (reST) markup language for defining additional formatting options in the generated documentation, however section [_3.8 Comments and Docstrings_](https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings) of the Google Python Style Guide does not specify how to use markups in docstrings. As a result, we decided to forbid reST markup in docstrings, except for the following cases: + +- Cross-referencing other objects using Sphinx text roles for the [Python domain](https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#the-python-domain) (as explained [here](https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#python-roles)). +- Very basic formatting markup to improve _readability_ of the generated documentation without obscuring the source docstring (e.g. ` ``literal`` ` strings, bulleted lists). + +We highly encourage the [doctest][doctest] format for code examples in docstrings. In fact, doctest runs code examples and makes sure they are in sync with the codebase. + +### Module structure + +In general, you should structure new Python modules in the following way: + +1. _shebang_ line: `#! /usr/bin/env python3` (only for **executable scripts**!). +2. License header (see `LICENSE_HEADER.txt`). +3. Module docstring. +4. Imports, alphabetically ordered within each block (fixed automatically by `ruff-formatter`): + 1. Block of imports from the standard library. + 2. Block of imports from general third party libraries using standard shortcuts when customary (e.g. `numpy as np`). + 3. Block of imports from specific modules of the project. +5. Definition of exported symbols (optional, mainly for re-exporting symbols from other modules): + +```python +__all__ = ["func_a", "CONST_B"] +``` + +6. Public constants and typing definitions. +7. Module contents organized in a convenient way for understanding how the pieces of code fit together, usually defining functions before classes. + +Try to keep sections and items logically ordered, add section separator comments to make section boundaries explicit when needed. If there is not a single evident logical order, pick the order you consider best or use alphabetical order. + +Consider configuration files as another type of source code and apply the same criteria, using comments when possible for better readability. + +### Ignoring QA errors + +You may occasionally need to disable checks from _quality assurance_ (QA) tools (e.g. linters, type checkers, etc.) on specific lines as some tool might not be able to fully understand why a certain piece of code is needed. This is usually done with special comments, e.g. `# noqa: F401`, `# type: ignore`. However, you should **only** ignore QA errors when you fully understand their source and rewriting your code to pass QA checks would make it less readable. Additionally, you should add a short descriptive code if possible (check [ruff rules][ruff-rules] and [mypy error codes][mypy-error-codes] for reference): + +```python +f = lambda: 'empty' # noqa: E731 [lambda-assignment] +``` + +and, if needed, a brief comment for future reference: + +```python +... +return undeclared_symbol # noqa: F821 [undefined-name] on purpose to trigger black-magic +``` + +## Testing + +Testing components is a critical part of a software development project. We follow standard practices in software development and write unit, integration, and regression tests. Note that even though [doctests][doctest] are great for documentation purposes, they lack many features and are difficult to debug. Hence, they should not be used as replacement for proper unit tests except in trivial cases. + + + +[doctest]: https://docs.python.org/3/library/doctest.html +[google-style-guide]: https://google.github.io/styleguide/pyguide.html +[mypy]: https://mypy.readthedocs.io/ +[mypy-error-codes]: https://mypy.readthedocs.io/en/stable/error_code_list.html +[pre-commit]: https://pre-commit.com/ +[pylint]: https://pylint.pycqa.org/ +[ruff-formatter]: https://docs.astral.sh/ruff/formatter/ +[ruff-linter]: https://docs.astral.sh/ruff/linter/ +[ruff-rules]: https://docs.astral.sh/ruff/rules/ +[sphinx]: https://www.sphinx-doc.org +[sphinx-autodoc]: https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html +[sphinx-napoleon]: https://sphinxcontrib-napoleon.readthedocs.io/en/latest/index.html# +[sphinx-rest]: https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html +[ci-docs]: docs/development/CI/infrastructure.md diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md index 55e3f0a..8c6b57a 100644 --- a/CONTRIBUTING.md +++ b/CONTRIBUTING.md @@ -1,20 +1,12 @@ -See the [Scientific Python Developer Guide][spc-dev-intro] for a detailed -description of best practices for developing scientific packages. +# Contributing -[spc-dev-intro]: https://learn.scientific-python.org/development/ +JaCe is an open-source project that accepts contributions from any individual or organization.

quite simple. + Since Jaxpr is essentially a list consisting of more or less simple instructions, we will process them one after the other. + For simplicity we will put each equation in its own state,

the SDFG, + - there is no possibility to return something. + + To support nested Jaxpr expressions the driver provides the possibility to clone/fork itself, see `self.fork()` for more. + Clones, i.e. the return values of `self.fork()`, also known as children or clone, have a unique identifier, called revision. + It is important that the revision is only unique within a family and during a

more. + These subtranslators are independent objects that are owned by the driver. + However, they are tightly coupled and thus a subtranslator is allowed to use the following private functions: + -

For example, maximum line length is set to 100 instead of 79 (although docstring lines should still be limited to 79). - According to subsection [_2.19 Power Features_](https://google.github.io/styleguide/pyguide.html#219-power-features), direct use of _power features_ (e.g. custom metaclasses, import hacks, reflection) should be avoided, but standard library classes that internally use these power features are accepted. Following the same spirit, we allow the use of power features in infrastructure code with similar functionality and scope as the Python standard library. +- For readability purposes, when a docstring contains more than the required summary line, we prefer indenting the first line at the same cursor position as the first opening quote, although this is not explicitly considered in the doctring conventions described in subsection [_3.8.1 Docstrings_](https://google.github.io/styleguide/pyguide.html#381-docstrings). Example: + + ```python + # single line docstring + """A one-line summary of the module or program, terminated by a period.""" + + # multi-line docstring + """ + A one-line summary of the module or program, terminated by a period. + + Leave one blank line. The rest of this docstring should contain an + overall description of the module or program. + """ + ``` + - According to subsection [_3.19.12 Imports For Typing_](https://google.github.io/styleguide/pyguide.html#31912-imports-for-typing), symbols from `typing` and `collections.abc` modules used in type annotations _"can be imported directly to keep common annotations concise and match standard typing practices"_. Following the same spirit, we allow symbols to be imported directly from third-party or internal modules when they only contain a collection of frequently used typying definitions. ### Common questions @@ -71,7 +86,7 @@ The terseness vs. helpfulness tradeoff should be more in favor of terseness for ### Docstrings -TODO: update to autodoc2 +TODO: update to `autodoc2` We generate the API documentation automatically from the docstrings using [Sphinx][sphinx] and some extensions such as [Sphinx-autodoc][sphinx-autodoc] and [Sphinx-napoleon][sphinx-napoleon].

This is basically a simple substitute class that can be used instead of a full jax variable. It is mostly usefull for creating arrays during testing. However, it should also be used to cretae variables for which we do not have anything. This essentially replaces the flags that allowed to explicitly specify shape and dtype in the `add_array()` function. --- .../translator/jaxpr_translator_driver.py | 54 ++++++------------ src/jace/util/__init__.py | 5 +- src/jace/util/jax.py | 55 ++++++++++++++++--- 3 files changed, 70 insertions(+), 44 deletions(-) diff --git a/src/jace/translator/jaxpr_translator_driver.py b/src/jace/translator/jaxpr_translator_driver.py index 25e8cec..821b454 100644 --- a/src/jace/translator/jaxpr_translator_driver.py +++ b/src/jace/translator/jaxpr_translator_driver.py @@ -327,7 +327,7 @@ def get_arrays(self) -> Mapping[str, ddata.Data]: def get_array( self, - name: str | jcore.Atom, + name: str | jcore.Atom | jutil.JaCeVar, ) -> ddata.Data: """Returns the SDFG `Data` object `name` referees to. @@ -338,7 +338,7 @@ def get_array( if isinstance(name, str): pass - elif isinstance(name, jcore.Atom): + elif isinstance(name, (jcore.Atom, jutil.JaCeVar)): name = self.map_jax_var_to_sdfg(name) else: raise TypeError(f"Does not know how to handle '{type(name).__name__}'.") @@ -350,19 +350,19 @@ def get_array( @overload def map_jax_var_to_sdfg( self, - jax_var: str | jcore.Atom, + jax_var: str | jcore.Atom | jutil.JaCeVar, ) -> str: ... @overload def map_jax_var_to_sdfg( self, - jax_var: str | jcore.Atom, + jax_var: str | jcore.Atom | jutil.JaCeVar, allow_fail: bool, ) -> str | None: ... def map_jax_var_to_sdfg( self, - jax_var: str | jcore.Atom, + jax_var: str | jcore.Atom | jutil.JaCeVar, allow_fail: bool = False, ) -> str | None: """Returns the name of the SDFG variable that the Jax variable `jax_var` is referring to. @@ -372,7 +372,7 @@ def map_jax_var_to_sdfg( allow_fail: If mapping is not known return `None` instead of raise `KeyError`.

This commit removes the `csdfg` member of the `TranslatedJaxprSDFG` object, thus it is not cached anymore. More importantly however, is the changes made to the compilation itself. Before the SDFG was modified (global variables, arg_names) and then compiled, and then restored. However, since the SDFG is part of teh CompiledSDFG this is inconsistent, for that reason the SDFG is deepcopied before processing. This is surely not the best solution, but should prevent some nasty bugs. --- src/jace/translator/translated_jaxpr_sdfg.py | 3 - src/jace/util/debug.py | 81 ++++++++------------ 2 files changed, 33 insertions(+), 51 deletions(-) diff --git a/src/jace/translator/translated_jaxpr_sdfg.py b/src/jace/translator/translated_jaxpr_sdfg.py index 2c99156..3a3bb6b 100644 --- a/src/jace/translator/translated_jaxpr_sdfg.py +++ b/src/jace/translator/translated_jaxpr_sdfg.py @@ -15,7 +15,6 @@ from jax import core as jax_core from jace import util -from jace.util import dace_helper as jdace @dataclass(init=True, repr=True, eq=False, frozen=False, kw_only=True, slots=True) @@ -29,7 +28,6 @@ class TranslatedJaxprSDFG: - `terminal_state` the last state in the state machine. - `inp_names` a `list` of the SDFG variables that are used as input, in the same order as `Jaxpr.invars`. - `out_names` a `list` of the SDFG variables that are used as output, in the same order as `Jaxpr.outvars`. - - `csdfg` a compiled SDFG object; Optional might be empyt.

This was Enrique's idea and it is really good, but it adds a lot of complexity. For several reasons (mainly open PR) the commit is split into two parts one that can is merged into the PR (this one) and once that contains the parts that are development only. Essentially we want allow code such as: ```python @jit def foo(...): ... foo1 = foo.lower(...args1) # Modify the list of internal translators, i.e. call `add_subtranslator()` foo2 = foo.lower(...args2) ``` because the list of translators is an implicit argument to the `jit` decorator, we expect that `foo2` is generated with the same translators as was `foo1`, see the next commit for a full description. This commit essentially adds two things: - the global list that stores the translator instances - makes all necessary changes such that stuff works. The managing of the global list is implemented such that it results in an immutable object. Thus every time it is mutated a new list is created. It might be a bit strange to do that, but the list is not changed that frequently (except upon loading) and it is only a shallow copy, since the translators are immutable themselves. This approach allows some nice optimization further down.

The previous commit changed the driver to use them and adds the necessary infrastructure of managing them. As before we want that in code such as: ```python @jit def foo(...): ... foo1 = foo.lower(...args1) # Modify the list of internal translators, i.e. call `add_subtranslator()` foo2 = foo.lower(...args2) ``` the second call to `lower()` uses the same translators as the first one. What sounds simple is in fact relatively hard. And we want that, in codes as ``` ```python def foo(...): ... foo1 = jace.jit(foo) # Modify the list of internal translators, i.e. call `add_subtranslator()` foo2 = jace.jit(foo) ``` `foo1` and `foo2` use different translators as they where constructed differently. As it is outlined inside in `JaceWrapped.__init__()` the feature of "being able to manipulate the set of active translators from the outside of a `JaceWrapped` object" is not really useful and we thus forbid it. As it is further outlined we _must_ make a copy (shallow copy is enough because the translators themselves are immutable) of the list of primitive translators that should be used, somewhere during the construction of a `JaceWrapped` object. Which we do, for many reasons inside `JaceWrapped.__init__()`. To include the set of used translators in the caching we use the address of the internal set of translators of the `JaceWrapped` object. We can do this because we have by construction an immutable set, since we copied it at construction. As an optimization, before we copy the set in `JaceWrapped.__init__()` we check if the set is the same as the global one (that is immutable). This means that in situations such as: ```python def foo(A): ... foo1 = jace.jit(foo)(A) A[1, 2] = 0 foo2 = jace.jit(foo)(A) ``` the code is only lowered once (this was not an intended design but a by product). This captures the main use case in which the translators are set at the beginning and then never again. We also included the Jax options to `jit`. Currently we only really handle the case of no options, which is probably okay. --- src/jace/jax/api.py | 74 ++++++++++++------------ src/jace/jax/stages/jace_wrapped.py | 73 +++++++++++++++++++---- src/jace/jax/stages/translation_cache.py | 49 ++++++++++++++-- src/jace/translator/managing.py | 2 + tests/test_decorator.py | 59 +++++++++++++++++++ 5 files changed, 201 insertions(+), 56 deletions(-) diff --git a/src/jace/jax/api.py b/src/jace/jax/api.py index dd3973e..6919f3b 100644 --- a/src/jace/jax/api.py +++ b/src/jace/jax/api.py @@ -9,12 +9,12 @@ from __future__ import annotations -from collections.abc import Callable +from collections.abc import Callable, Mapping from typing import Any import jax as _jax_jax -from jace import jax as jjax, util +from jace import jax as jjax, translator from jace.jax import api_helper @@ -22,51 +22,51 @@ def jit( fun: Callable | None = None, /, + sub_translators: Mapping[str, translator.PrimitiveTranslator] | None = None, **kwargs: Any, ) -> jjax.JaceWrapped: - """Jace wrapper for `jax.jit`. + """Jace's replacement for `jax.jit` (just-in-time) wrapper. - Wraps the computation `fun` into a wrapped instance, that can either be traced or compiled. - For more information see `jace.jax.stages`. + It works the same way as `jax.jit` does, but instead of using XLA the computation is lowered to DaCe. + It supports the same arguments as `jax.jit` (although currently not) does. + In addition it accepts some Jace specific arguments. + + Args: + sub_translators: Use these subtranslators for the lowering to DaCe.

This was Enrique's idea and it is really good, but it adds a lot of complexity. For several reasons (mainly open PR) the commit is split into two parts one that can is merged into the PR (this one) and once that contains the parts that are development only. Essentially we want allow code such as: ```python @jit def foo(...): ... foo1 = foo.lower(...args1) # Modify the list of internal translators, i.e. call `add_subtranslator()` foo2 = foo.lower(...args2) ``` because the list of translators is an implicit argument to the `jit` decorator, we expect that `foo2` is generated with the same translators as was `foo1`, see the next commit for a full description. This commit essentially adds two things: - the global list that stores the translator instances - makes all necessary changes such that stuff works. The managing of the global list is implemented such that it results in an immutable object. Thus every time it is mutated a new list is created. It might be a bit strange to do that, but the list is not changed that frequently (except upon loading) and it is only a shallow copy, since the translators are immutable themselves. This approach allows some nice optimization further down.

The reason for this is quite interesting actually and there are several things that interact together to create the bug. One part of the problem is, that we do not use scalars but only arrays and one part is probably a bug inside the code generator. With enabled optimizations, start indexes of the dynamic slices are turned into symbols, which are implemented as (C) scalars. However, if optimizations are disabled the start index is stored inside an array with length one. In the Memlet, that we use to extract we essentially write something like `iteration_variable + start_index` which implies that `start_index` is a scalar, and if such an SDFG is compiled, then the code generator will generate `a[iteration_variable + start_index]`, but this is a compilation error, since `start_index` is a pointer and not a scalar. The simple fix just to write `iteration_variable + start_index[0]` also does not work, as this seems to violate SDFG semantic because the code generator generates something like `a[iteration_variable + start_index(0)]` which is an error because `start_index` is obvious not a function. Because there is no simple solution, this commit disables the tests for the slicing as a temporary solution. The proper solution, which I will now implement, is to support scalars inside the translator.

I do not like it, but it is fully in line with what the black manpage tells: By using it, you agree to cede control over minutiae of hand-formatting. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. You will save time and mental energy for more important matters. This follows the mantra "what the formater does on the _big scale_ is _always_ correct regardless how it looks". Disabeling it, is still allowed locally. --- docs/conf.py | 22 +---- noxfile.py | 8 +- pyproject.toml | 1 + src/jace/api.py | 7 +- src/jace/optimization.py | 15 +--- src/jace/stages.py | 64 +++----------- .../translator/jaxpr_translator_builder.py | 86 ++++--------------- src/jace/translator/post_translation.py | 3 +- src/jace/translator/primitive_translator.py | 15 ++-- .../primitive_translators/__init__.py | 4 +- .../primitive_translators/alu_translator.py | 16 +--- src/jace/util/__init__.py | 6 +- src/jace/util/dace_helper.py | 10 +-- src/jace/util/jax_helper.py | 26 ++---- src/jace/util/traits.py | 24 ++---- src/jace/util/translation_cache.py | 59 +++---------- tests/test_jaxpr_translator_builder.py | 37 ++------ 17 files changed, 85 insertions(+), 318 deletions(-) diff --git a/docs/conf.py b/docs/conf.py index cb0bb09..e902d98 100644 --- a/docs/conf.py +++ b/docs/conf.py @@ -26,28 +26,14 @@ ] source_suffix = [".rst", ".md"] -exclude_patterns = [ - "_build", - "**.ipynb_checkpoints", - "Thumbs.db", - ".DS_Store", - ".env", - ".venv", -] +exclude_patterns = ["_build", "**.ipynb_checkpoints", "Thumbs.db", ".DS_Store", ".env", ".venv"] html_theme = "furo" -myst_enable_extensions = [ - "colon_fence", -] +myst_enable_extensions = ["colon_fence"] -intersphinx_mapping = { - "python": ("https://docs.python.org/3", None), -} +intersphinx_mapping = {"python": ("https://docs.python.org/3", None)} -nitpick_ignore = [ - ("py:class", "_io.StringIO"), - ("py:class", "_io.BytesIO"), -] +nitpick_ignore = [("py:class", "_io.StringIO"), ("py:class", "_io.BytesIO")] always_document_param_types = True diff --git a/noxfile.py b/noxfile.py index 3772f2d..2154c16 100644 --- a/noxfile.py +++ b/noxfile.py @@ -79,13 +79,7 @@ def build_api_docs(session: nox.Session) -> None: session.install("sphinx") session.chdir("docs") session.run( - "sphinx-apidoc", - "-o", - "api/", - "--module-first", - "--no-toc", - "--force", - "../src/jace", + "sphinx-apidoc", "-o", "api/", "--module-first", "--no-toc", "--force", "../src/jace" ) diff --git a/pyproject.toml b/pyproject.toml index 3556e8a..1746b5a 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -102,6 +102,7 @@ src = ["src"] [tool.ruff.format] docstring-code-format = true +skip-magic-trailing-comma = true [tool.ruff.lint] extend-select = [ diff --git a/src/jace/api.py b/src/jace/api.py index 9f128b3..46e15b2 100644 --- a/src/jace/api.py +++ b/src/jace/api.py @@ -21,12 +21,7 @@ from collections.abc import Callable, Mapping -__all__ = [ - "grad", - "jacfwd", - "jacrev", - "jit", -] +__all__ = ["grad", "jacfwd", "jacrev", "jit"] @overload diff --git a/src/jace/optimization.py b/src/jace/optimization.py index 7240b79..92b52e4 100644 --- a/src/jace/optimization.py +++ b/src/jace/optimization.py @@ -36,21 +36,12 @@ class CompilerOptions(TypedDict, total=False): # TODO(phimuell): Add a context manager to modify the default. -DEFAULT_OPTIMIZATIONS: Final[CompilerOptions] = { - "auto_optimize": True, - "simplify": True, -} +DEFAULT_OPTIMIZATIONS: Final[CompilerOptions] = {"auto_optimize": True, "simplify": True} -NO_OPTIMIZATIONS: Final[CompilerOptions] = { - "auto_optimize": False, - "simplify": False, -} +NO_OPTIMIZATIONS: Final[CompilerOptions] = {"auto_optimize": False, "simplify": False} -def jace_optimize( - tsdfg: translator.TranslatedJaxprSDFG, - **kwargs: Unpack[CompilerOptions], -) -> None: +def jace_optimize(tsdfg: translator.TranslatedJaxprSDFG, **kwargs: Unpack[CompilerOptions]) -> None: """Performs optimization of the translated SDFG _in place_.
