cupynumeric-parallel-data-load SKILL.md skillA

cupynumeric-parallel-data-load from nvidia/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add nvidia/skills/cupynumeric-parallel-data-load@v1.0.0

Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Load a sharded, on-disk dataset (sharded .npy, Parquet/Arrow, raw binary, sharded HDF5, custom layouts) into a distributed cuPyNumeric ndarray via a manual partition + leaf @task launch with CPU/OMP/GPU variants. Use when no single-call loader fits, including when per-shard row counts differ across files. Prefer cupynumeric.load or legate.io.hdf5.from_file when they apply.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Parallel sharded data -> cupynumeric load

**Why this skill exists.** cupynumeric mirrors NumPy's array API, including
`cupynumeric.load` for a single `.npy` file. Beyond that, file *loading* lives
in Legate, not cupynumeric:

| Format | Built-in loader |
|---|---|
| Single `.npy` | `cupynumeric.load(path)` (NumPy-API parity) |
| HDF5 (single file) | `legate.io.hdf5.from_file` / `from_file_batched` |
| Sharded multi-file (any format), Parquet/Arrow, raw binary, custom layouts | **No built-in loader — this skill.** |

This skill shows the canonical way to fill the gap in the last row:
write a Legate Python task that calls the third-party reader the
format needs (`h5py`, `pyarrow`, `np.memmap`, ...) inside the
task body, and let Legate distribute the reads across GPUs / nodes.
For the formats with a built-in loader, prefer it unless you need a
custom in-task body (mmap-based loader, format-specific decoder,
sidecar metadata, partial / sharded reads).

Canonical pattern: **manual partition + manual task launch, sized to
the machine, not the files.** Only axis 0 is sharded; trailing axes
ride along inside each tile. Per-shard row counts may differ across
…

How to install

The exact contents, by fingerprint
mdr add nvidia/skills/cupynumeric-parallel-data-load@sha256:2ae4b284c285b5be

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
