Walkthrough

The Jupyter notebook 3-hpc-job.ipynb was fully replaced with a new version that maintains the same instructional content and code examples but uses a more compact JSON format. The update also introduces a section on the native flux framework, updates the Python kernel version, and results in minor output differences.

Changes

File(s)	Change Summary
notebooks/3-hpc-job.ipynb	Replaced entire notebook with a compact JSON format; preserved instructional content and code; added section on native flux; updated kernel version; minor output and cache file name changes.

Possibly related PRs

• Fixes for documentation #560: Minor textual clarifications in the HPC job notebook and documentation; related as both PRs modify the same notebook but differ in scope.
• execute notebooks on mybinder #610: Updates kernel specification and metadata in 3-hpc-job.ipynb to use the Flux environment; both PRs involve metadata and environment updates for the notebook.
• Update Documentation #558: Updates documentation and restructures HPC executor terminology and notebook filenames, directly relating to the notebook replacement in this PR.

Poem

In a warren of code, a notebook anew,
Compact and tidy, its format we strew.
With flux and with SLURM, the examples remain,
While kernels hop forward, outputs sustain.
A rabbit’s delight in this digital den—
The lessons endure, again and again!

20-25: ⚠️ Potential issue

Inconsistent import and executor usage
You import SlurmJobExecutor but then call SlurmAllocationExecutor(). This will raise a NameError. Either change the import to from executorlib import SlurmAllocationExecutor or update the code to use SlurmJobExecutor.

🧹 Nitpick comments (2)

notebooks/3-hpc-job.ipynb (2)

92-96: Prefer direct import of FluxExecutor
Instead of import flux.job and flux.job.FluxExecutor, consider:

from flux.job import FluxExecutor

for clarity and consistency with other imports.

106-107: Remove empty code cell
The final code cell is empty and can be removed to keep the notebook clean.

1-3: Kernel spec update looks good
The bump from Python 3.12.9 to 3.12.11 is appropriate and matches the new runtime.
