Adds two new blueprints for all-in-cloud and hybrid-cloud EDA workloads #4931

okrause · 2025-12-03T15:12:40Z

This PR adds two blueprints and a README.MD file to a new community/examples/eda folder. It also updates a few README files.

Both blueprints use Google Cloud NetApp Volumes as the shared NFS storage for the compute cluster.

It was developed and reviewed a #4771. This is a replacement PR for the merge.

Summary of Changes

Hello @okrause, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly expands the available reference architectures by introducing two new blueprints tailored for Electronic Design Automation (EDA) workloads on Google Cloud. These additions provide comprehensive solutions for both fully cloud-native and hybrid cloud environments, focusing on optimizing performance and scalability for demanding EDA applications. The core of these solutions relies on Google Cloud NetApp Volumes for shared storage and the Slurm scheduler for compute management, offering flexible deployment options to meet diverse user needs.

Highlights

New EDA Blueprints: Introduced two new blueprints for Electronic Design Automation (EDA) workloads: one for all-in-cloud deployments and another for hybrid-cloud scenarios.
Google Cloud NetApp Volumes Integration: Both new blueprints leverage Google Cloud NetApp Volumes for high-performance shared NFS storage, crucial for EDA applications.
Hybrid Cloud Capabilities: The hybrid-cloud blueprint specifically enables bursting of on-premises EDA workloads to Google Cloud by utilizing NetApp FlexCache for efficient data caching.
Slurm Workload Scheduler: The blueprints integrate with the Slurm workload scheduler to manage compute clusters, providing a robust environment for EDA tasks.
Documentation Updates: Updated various README files across the repository to reflect the addition of these new EDA blueprints and their features, including a dedicated README for the EDA examples.

Code Review

This pull request introduces two new blueprints for Electronic Design Automation (EDA) workloads, one for all-in-cloud and another for hybrid-cloud scenarios. The changes include the new blueprint YAML files, a comprehensive README for the EDA examples, and updates to existing documentation to include these new examples. The blueprints are well-structured and provide a solid starting point for users. My review includes several suggestions to improve the documentation for clarity and correctness, as well as a high-severity recommendation to refactor a complex and likely incorrect network configuration in both blueprint files to a simpler, standard, and more readable format.

Hi @okrause,
I see that this branch is out-of-date with the base branch, could you please rebase?

I'm also curious to understand why the previous PR #4771 was closed? Did rebasing not fix the git history? I'm asking so that we don't get into the same issue here or later :)

I had recommended Oliver to create a new PR because the commit history in the older one was intertwined with other commits probably due to merge instead of a rebase.

@okrause this branch cannot be merged due to it not in line with develop. Please perform teh following

git fetch upstream
git rebase upstream/develop
git push origin eda-blueprints-new --force

Thanks for the contribution.

Neelabh94 · 2026-01-12T04:48:30Z

@okrause The PR-validation (required) test is failing due to missing region and zone in the blueprint. Please add the missing params, re-run the test and re-assign it to us.

okrause · 2026-01-14T14:03:11Z

@Neelabh94 Thank you for the hint. I added regions and zones. I tested community/examples/eda/eda-all-on-cloud.yaml and it worked fine.
community/examples/eda/eda-hybird-cloud.yaml will fail, since it relies on pre-existing network and volumes, which are obviously not there. How can I tell the tests not to run this blueprint?

Update: Also squashed prior commits and force pushed.

Neelabh94 · 2026-01-20T02:09:36Z

How can I tell the tests not to run this blueprint?

Please add your blueprint into the exclude list of unit tests here-- https://github.com/GoogleCloudPlatform/cluster-toolkit/blob/main/tools/validate_configs/validate_configs.sh#L131
