Walkthrough

The changes remove the existing ASV benchmark workflow (pr_asv.yml), introduce a new GPU benchmark workflow running on AWS EC2 instances (pr_aws_gpu_asv.yml), and update the AWS GPU test workflows (pr_aws_gpu_tests.yml, push_aws_gpu_tests.yml) to use a new EC2 instance type, improve artifact naming, and streamline log retrieval by leveraging SSM combined output logs.

  • @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

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.
