Handle some zero-sized corner cases in dlpack interop

3

## Description Previously, we did not explicitly check for zero-sized inputs in to/from_dlpack. cupy>=11 changes behaviour in how it provides information for zero-sized arrays (strides of empty tensors were previously...

Heap storage for big temporaries

6

Sometimes, when doing very high order things, we need big (multi-megabyte) temporaries. They are quite long-lived so I'd be happy if there were a way to control allocation of the...

Putting `dask-worker-space` in `/tmp` is unfriendly on shared systems

1

Since d59500ea97c02753eac9d42951d9c4a5d4f17685 (#6658), launching workers can fail on shared systems if someone else happens to be running at the same time (since they will have created `/tmp/dask-worker-space` and we won't...

Nested configurables

2

We're looking to use traitlets to enforce type checking in the configuration of a coastal ocean model thetis (github.com/thetisproject/thetis). Right now, we have a tree of configuration options. For example:...

[ENH] Update flake8 version in pre-commit

4

At present, the pre-commit environment uses flake8 version 3.8.3. As part of moves to support Python 3.10, we will need to go to at least version 4 (to include https://github.com/PyCQA/flake8/pull/1374)....

[ENH]: serialization schema cleanup

13

Followup from #10784. Hyphens and underscores are used inconsistently when separating names in metadata keys in `serialize`; go through and standardise on one choice (hyphens seem more popular).

[ENH] More type-stubs in the mypy pre-commit environment?

7

Following on from #11640 (specifically https://github.com/rapidsai/cudf/pull/11640#discussion_r961551760) a question arises as to how complete we should make the mypy pre-commit environment in terms of supported typestubs. Status quo: The version of...

Consistent deadlock with `shuffle="p2p` when merging dataframes with many partitions

6

**What happened**: The code below (needs `typer` in addition to usual dask/distributed/pandas/numpy) pretty consistently hangs after a worker `AssertionError` when using the `p2p` shuffle option. If I have both many...

Upstream in Firedrake we hook in to the PETSc citations mechanism so that someone can run a simulation and add the PETSc option `-citations` to show. It would be nice...

When building specific functionals, we pass a name to the superclass constructor that is just a label. A few of these superclass init calls have a functional name that doesn't...
