Dace

This release contains backports of minor fixes following the release of v1.0.0.

**Full Changelog**: https://github.com/spcl/dace/compare/v1.0.0...v1.0.1

We are happy to announce DaCe version 1.0!

It is a major release milestone, and we went over many of the known issues over the years to ensure that this is the most stable version we can release without making fundamental changes to the framework. The Stateful DataFlow multiGraph (SDFG) intermediate representation used in this version is faithful to the original paper, which was published in 2019.

On a fundamental level, this release is no different from a minor version release (this version could have been DaCe 0.17), so there are no breaking changes from v0.x.

We would like to thank [everyone](https://github.com/spcl/dace/graphs/contributors) who contributed to DaCe over the years and helped reach this milestone! It would not have been possible without you.

**Full Changelog**: https://github.com/spcl/dace/compare/v0.16.1...v1.0.0

We are happy to announce the first release candidate of DaCe version 1.0!

This version uses the SDFG intermediate representation as published in the original Stateful Dataflow Multigraphs paper, which has been stable for quite some time.

On a fundamental level, this release is no different from a minor version release (this version could have been DaCe 0.17). However, with this release we would like to emphasize stability rather than new features.

If you are using DaCe and have a critical or blocking issue that makes it unstable, please create an issue and refer to it in the release discussion, so that we can add it to our release plan. Thank you for using DaCe!

What's Changed

The main purpose of this release is to require NumPy < 2 for DaCe, since NumPy 2.0.0 contains breaking changes which aren't compatible with DaCe currently.

Recently, NumPy 2.0.0 has been released: https://numpy.org/news/#numpy-200-released

The release comes with documented breaking changes. Unfortunately, DaCe is currently not compatible with these changes. This also affects the [recent 0.16 release](https://github.com/spcl/dace/releases/tag/v0.16) of DaCe. Hence, we adjust our dependency requirements to use NumPy < 2 as a temporary work-around in this PR:

Fix numpy version to < 2.0 by phschaad in https://github.com/spcl/dace/pull/1601

Long term, we are tracking adding support for NumPy 2 in DaCe in this issue: https://github.com/spcl/dace/issues/1602

Fix constant propagation failing due to invalid topological sort by phschaad in https://github.com/spcl/dace/pull/1589

This changeset has also landed in DaCe's development branch earlier. It fixes an issue where the ConstantPropagation pass can fail for certain graph structures.

What's Changed

CI/CD pipeline for NOAA & NASA weather and climate model by FlorianDeconinck & BenWeber42 in https://github.com/spcl/dace/pull/1460, https://github.com/spcl/dace/pull/1478 & https://github.com/spcl/dace/pull/1575

Our collaborators NOAA & NASA have successfully used DaCe as an optimization framework and back-end for some of the [components of their climate and weather model](https://github.com/NOAA-GFDL/PyFV3). Particularly, the FV3 dycore and GFS physics parametrization have been ported to a combination of [GT4Py](https://github.com/GridTools/gt4py) Python DSL and DaCe. DaCe is used within their stack as a stencil backend and as a full-program optimizer integrating stencils and glue-code together.

With this CI/CD pipeline, we run various checks for those components on every change to DaCe. This is an important step for DaCe to ensure stability for real-world applications that utilize DaCe. We are very grateful for this contribution and the collaboration with NOAA & NASA.

Changed default of serialize_all_fields to False by BenWeber42 in https://github.com/spcl/dace/pull/1564

This feature was already implemented in the previous 0.15.1 release in https://github.com/spcl/dace/pull/1452, but not enabled by default. In this release, we are changing the default so that only fields with non-default values are serialized. This generally leads to a reduction in file size for SDFGs.

Since each DaCe version stores the default values of each field, it is still possible to recover these missing values. Default values should rarely change across different DaCe versions. Nevertheless, we want to caution users & developers when using SDFG files with different DaCe versions.

Analysis passes for access range analysis by tbennun in https://github.com/spcl/dace/pull/1484

Adds two analysis passes to help with analyzing data access sets: access ranges and Reference sources. To enable constructing sets of memlets, this PR also reintroduces data descriptor names to memlet hashes.

Reference-to-View pass and comprehensive reference test suite by tbennun in https://github.com/spcl/dace/pull/1485

Implements a reference-to-view pass (converting references to views if they are only set to one particular subset). Also improves the simplify pipeline in the presence of Reference data descriptors and adds multiple tests that use references.

Ndarray strides by alexnick83 in https://github.com/spcl/dace/pull/1506

The PR adds support for custom strides to `dace.ndarray`. Furthermore, the stride unit is number of elements, in contrast to NumPy/CuPy, where it is number of bytes. Custom strides are not supported for `numpy.ndarray` and `cupy.ndarray`.

Structure Support to NestedSDFGs and Python Frontend by alexnick83 in https://github.com/spcl/dace/pull/1366

Adds basic support for nested data (Structures) to the Python frontend. It also resolves issues with the use of Structures in nested SDFG scopes (mostly code generation).

Generalize StructArrays to ContainerArrays and refactor View class structure by tbennun in https://github.com/spcl/dace/pull/1504

This PR enables the use of an array data descriptor that contains a nested data descriptor (e.g., ContainerArray of Arrays). Its contents can then be viewed normally with View or StructureView.
With this, concepts such as jagged arrays are natively supported in DaCe (see test for example).
Also adds support for using ctypes pointers and arrays as arguments to SDFGs.

This PR also refactors the notion of views to a View interface, and provides views to arrays, structures, and container arrays. It also adds a syntactic-sugar/helper API to define a view of an existing data descriptor.

Add support for distributed compilation in DaceProgram by kotsaloscv in https://github.com/spcl/dace/pull/1551 & https://github.com/spcl/dace/pull/1555

Adds configurable support for distributed compilation (MPI) to the Python front-end (via mpi4py). Distributed compilation can be enabled with the `distributed_compilation` parameter in the `dace.program` decorator.
