Summary of Changes

Hello @PranjalC100, 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 enhances the microbenchmarking infrastructure by improving environment detection for GCE VMs. It specifically addresses connectivity challenges when running benchmarks from Cloudtop workstations by ensuring that SSH connections from these environments correctly utilize external IP addresses or IAP, while maintaining internal IP usage for standard GCE VM-to-VM communication. This change aims to make the benchmarking setup more robust and reliable across different execution environments.

Highlights

• Cloudtop Environment Detection: The is_running_on_gce() function now includes logic to detect if the script is running within a Cloudtop environment by checking for the existence of /usr/local/google/home.
• Forced External IP for Cloudtop: When a Cloudtop environment is detected, is_running_on_gce() explicitly returns False, which forces SSH connections to use external IP addresses or IAP, resolving connectivity issues for Cloudtop users.
• Refined SSH Command Construction: The wait_for_ssh() function has been updated to streamline the appending of SSH arguments to the gcloud compute ssh command, ensuring correct behavior for both internal and external IP connection scenarios.

Code Review

This pull request updates the microbenchmarking scripts to support running from a Cloudtop environment. The main changes involve detecting the Cloudtop environment to force the use of external IPs for SSH and updating the SSH command construction.

My review focuses on improving the robustness and maintainability of these changes. I've pointed out a potential issue where the SSH command for Cloudtop environments might hang due to interactive prompts for host key verification. I've also suggested improvements for code clarity by removing a debug print statement and replacing a hardcoded path with a constant. These changes will make the script more reliable and easier to maintain.
