The Zen Lake Architecture project demonstrates the feasibility of high-precision computation of π using modest hardware. By leveraging a 10-year-old PC, specifically the HP ProDesk 600 G2 SF, this guide showcases the achievement of calculating 50 billion digits of π in just 22 hours using y-cruncher. It serves as a practical resource for anyone looking to perform stable and reproducible π computations, scaling up to 100 billion digits on budget-friendly hardware.

Key Features

• Accessibility: High-precision computation is now achievable without needing supercomputers or corporate resources. This project empowers individuals to undertake substantial mathematical calculations in their own environment.
• Collaborative Design: The architecture has been honed through a collaborative effort between human users and AI tools, ensuring that the methodology is both innovative and effective.

Important Considerations

Utilizing this project entails notable stress on hardware. Participants should be aware of the following:

• Extensive use of SSD, RAM, and CPU resources.
• Potential risks to SSD lifespan due to heavy operations.
• Increased heat and power consumption during long computational tasks.

Example Hardware Configuration

An exemplary setup includes:

• PC: HP ProDesk 600 G2 SF (Small Form Factor)
• CPU: Intel Core i3-6100 (2 cores, 4 threads)
• RAM: 16GB DDR4
• USB SSD: 500GB (up to 500MB/sec)
• Internal SSD: 125GB (SATA)
• OS: Windows 10 (64-bit)

Storage Layout & Virtual Memory Settings

A successful configuration includes:

• G: USB SSD 500GB: NTFS format with a 64KB cluster size, designated for y-cruncher and set with 24GB of virtual memory.
• C: Internal SSD 125GB: Hosts the OS and also configured with 24GB of virtual memory.

Execution Steps

For optimal performance:

1. Configure virtual memory to 24GB on both G: and C:
2. Execute y-cruncher from the USB SSD using elevated permissions.
3. Monitor the usage of RAM and virtual memory throughout the computation.
4. Save results upon completion.

Educational Value

This project aims to inspire educators and researchers to replicate and explore high-precision computations. It invites experimentation with various hardware configurations to optimize SSD types, RAM capacities, and virtual memory settings, emphasizing stability and reproducibility in calculations.
