TR GPU Monitor

The monitor makes availability, memory pressure, stale data, and detailed GPU state visible without exposing host credentials to another application.

Overview

The SwiftUI app polls configured hosts, owns notifications and persistence, and can provide a sanitized summary to Studio after compatibility review.

Example workflow

Example workflow

Compare three synthetic hosts before choosing capacity for a training run.

  1. Check the overview

    See one available host, one high-memory host, and one stale host.

  2. Find memory pressure

    Identify demo-gpu-02 before starting another workload.

  3. Compare details

    Review utilization and memory for two synthetic A100 hosts.

    TR GPU Monitor comparison of two demo A100 hosts.
    Compare utilization and memory details across hosts. Host names, GPU values, and warning times are synthetic demo data.

  4. Inspect the stale state

    Confirm the unreachable warning without attempting a real connection.

    TR GPU Monitor stale warning for a demo host with retry disabled.
    Review stale data without attempting a real connection. Host names, GPU values, and warning times are synthetic demo data.

Key features

  • Multi-host availability overview
  • GPU utilization and memory detail
  • Stale and unreachable states
  • Local notifications
  • Sanitized summary boundary

Data and privacy

The approved scenario uses demo-gpu-01 through demo-gpu-03. It contains no SSH configuration, username, hostname, process argument, or credential.

Tech stack

Languages

  • Swift

Interface

  • SwiftUI

Data

  • SQLite

Technology icons are repository-owned category symbols; the verified technology name remains visible.

Studio relationship

Studio may receive a short sanitized summary and open the monitor; it never receives SSH credentials or full process arguments.

Current state

Standalone host monitoring, GPU detail, persistence, notifications, and error states work locally. Studio status sharing remains under review.

Current limitations

  • A full local Xcode build requires selecting the complete Xcode developer directory.
  • Final package and menu-bar identity checks remain.

Technical notes

  • SwiftUI owns the presentation layer.
  • SQLite or UserDefaults can store local state.
  • SSH credentials and detailed processes remain inside the monitor.

Next milestones

  • Complete full Xcode and packaged-app verification.
  • Review the sanitized provider contract with Studio.
