hyperCPU.app

Granular per-core Apple Silicon process supervisor, automated agent loop throttling, and thermal load balancing.

1. Executive Summary

Unchecked background scripts, infinite LLM agent retries, and runaway compiler processes can monopolize CPU resources, causing fan noise, high thermal pressure, and sluggish system responsiveness. Traditional activity monitors show aggregate percentages but fail to intervene before performance degrades.

hyperCPU.app is an autonomous process supervisor built natively for Apple Silicon and Intel Macs. By tracking per-core performance (P-cores vs. E-cores) and thread behavior at high frequencies, hyperCPU automatically detects runaway CPU loops and applies progressive throttling (renicing, SIGSTOP duty cycling, or priority deprioritization)—preserving seamless foreground workstation responsiveness during intensive background tasks.

2. Key Capabilities

• Per-Core Architecture Awareness: Granular visualization of performance and efficiency cores on Apple Silicon (M1 through M5).
• Automated Runaway Throttling: Detects runaway agent loops and applies non-destructive throttling before thermal throttling kicks in.
• Full-Height Menu Bar Interface: Modern, expansive vertical popover panel matching the intuitive UX of RTTy and Usage.
• Fleet Mesh Integration: Coordinates CPU pressure signals across cluster nodes via Tyrell to prevent task overload on hot machines.
