[FEA] Define unary operations like `__neg__`, `__pos__`, `__abs__` and `__invert__` for `Column`.

3

Currently, invoking Python's builtin unary operators on columns raises: ```python >>> s = cudf.Series([1, 2, 3]) >>> -s._column # TypeError ``` This came up in https://github.com/rapidsai/cudf/pull/10564. A workaround is to...

Cannot use `<limits>` and `<cuda/std/limits>` in the same source file

Invoking jitify with the following source file: ``` #include #include ``` as follows: ``` jitify2_preprocess -std=c++11 -D__CUDACC_RTC__ test.hpp ``` results in: ``` Error processing source file test.hpp Compilation failed: NVRTC_ERROR_COMPILATION...

[ENH] Propagate exceptions from `cdef` functions by default

20

Closes https://github.com/cython/cython/issues/4280 This PR enables Python exceptions to be propagated by (non-extern) `cdef` functions by default. The behaviour for `extern` functions is unchanged. It also adds a new `noexcept` modifier...

[BUG] Potentially unsafe releasing of the GIL in `DeviceBuffer`

11

## The problem When allocating memory in the constructor of `DeviceBuffer`, we release the GIL. See [here](https://github.com/rapidsai/rmm/blob/5584a0ccdb4d8d68df96eb6e8121a3baa4f4e168/python/rmm/_lib/device_buffer.pyx#L83-L98). After the allocation, [we store a reference to the current memory resource](https://github.com/rapidsai/rmm/blob/5584a0ccdb4d8d68df96eb6e8121a3baa4f4e168/python/rmm/_lib/device_buffer.pyx#L97) associated...

[QST] Move `cudf.Buffer` to `rmm`

28

Question regarding moving `cudf.Buffer` to `rmm`: * `rmm.DeviceBuffer` is a Cython wrapper around the C++ class `rmm::device_buffer`. * `cudf.Buffer` more generally represents an untyped device memory allocation: ``` buf =...

[FEA] Allow setting `pool_size` with human-readable string

4

It would be nice to be able to set the `initial_pool_size` with a string like `"500mb"` or `"2gb"` as opposed to integer sizes like 500000000. We could vendor the code...

AMGX_solver_get_status() requires monitor_residual.

3

If `monitor_residual` is not set or set to 0 in the config, then `AMGX_solver_get_status()` silently returns 0 (success) regardless of convergence. Perhaps this should be made explicit in the reference...

[FEA] TZiF reader to support timezone-aware operations

1

Related: https://github.com/rapidsai/cudf/issues/10047, https://github.com/rapidsai/cudf/issues/2477. It is desirable to be able to do timezone-aware operations in cuDF. One relatively simple approach is to load the IANA [time zone database](https://www.iana.org/time-zones) into cuDF as...

Fix consumption of CPU-backed interchange protocol dataframes

## Description Closes #11245. This PR fixes a bug in our code that consumes a protocol DataFrame that is backed by CPU memory. Depends on #11617. ## Checklist - [x]...
