Walkthrough

The pull request introduces enhanced validation for maximum workers across different execution backends (Flux and SLURM). The changes modify the create_executor function to use backend-specific validation functions, improving the modularity and clarity of resource allocation. Type annotations are added to the validate_max_workers function in the Flux backend, and a new validation function is implemented for the SLURM backend to ensure that requested cores do not exceed available resources.

Changes

Poem

🐰 Cores dancing, workers in line,
Validation's magic, simply divine!
Flux and SLURM, each with their might,
Ensuring resources are just right.
A rabbit's code, precise and neat,
Making executors a computational treat! 🖥️

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
