Good Works for AI workloads

Posted on by lechuck park

The infographic outlines a comprehensive strategy for optimizing AI workloads by balancing computational performance with power efficiency and thermal management.

1. GPU Parallelism

This section focuses on distributing the computational load to prevent “hot spots” (heat concentration) within the hardware.

  • Core Strategy: Adjusting model partitioning and tensor parallelism levels to balance the thermal load across multiple GPUs.
  • Key Techniques: * Tensor Parallelism: Splitting individual tensors across devices.
    • Pipeline Parallelism: Distributing different layers of a model across various GPUs.
    • FSDP (Fully Sharded Data Parallelism): Sharding model states to minimize memory overhead while maintaining high throughput.

2. DVFS (Dynamic Voltage and Frequency Scaling)

This represents the hardware-level power management used to reduce energy waste.

  • Core Strategy: Dynamically adjusting GPU clock speeds and voltages based on the real-time workload to minimize unnecessary heat generation.
  • Key Techniques:
    • P-State and C-State Control: Managing active performance and idle power states.
    • Hardware Power Capping (TDP Limit): Setting strict thermal design power limits to prevent overheating.
    • Clock/Power Gating: Shutting down power to inactive portions of the chip.

3. Cooling Control

This shifts the focus from reactive cooling to proactive and autonomous thermal infrastructure management.

  • Core Strategy: Pre-emptively adjusting cooling parameters (fan speeds, coolant temperatures) based on predicted heat generation from incoming workloads.
  • Key Techniques:
    • CDU and DLC Optimization: Maximizing the efficiency of Coolant Distribution Units and Direct Liquid Cooling systems.
    • Telemetry-based Proactive Control: Using real-time data to adjust infrastructure before temperatures spike.
    • AI-driven Autonomous Cooling: Utilizing AI for anomaly detection and self-regulating thermal environments.

The tribal knowledge pipeline

Posted on by lechuck park

Core Summary: The Tribal Knowledge Pipeline

The absolute bottleneck for autonomous AI intelligence is the difficult process of transforming scattered, unstructured human knowledge into clean, machine-readable data.
The 4-Step Process:

  1. Knowledge Fragmentation: Identifying scattered operational know-how hidden in human memory, binders, and spreadsheets.
  2. Parsing & Chunking: Ingesting and breaking down these raw, unstructured inputs.
  3. Normalization: Standardizing the broken-down data into structured formats like Markdown or JSON.
  4. Semantic Search (RAG): Storing the normalized data in a Vector Database so the AI can accurately retrieve and use it to answer questions.
  5. The Ultimate Takeaway:
    Converting decades of unstructured data is an extremely difficult data engineering challenge, but it is mandatory. Without this pipeline providing clean, structured context, an AI agent’s retrieval quality degrades and it cannot reason effectively.

In short: Better data in, smarter AI out.

Harness Engineering

The Evolution of LLM Utilization: Toward Autonomous Agents

This slide illustrates the evolutionary roadmap of adopting Large Language Models (LLMs) within enterprise operations, transitioning from basic user inputs to fully automated, agentic workflows. The architecture is broken down into three distinct phases:

  • Phase 1: Prompt Engineering (Interactive)This represents the foundational stage of LLM interaction. At this level, the quality of the output depends entirely on human input—the ability to “Make a Nice Question.” It is a strictly interactive, 1:1 process that relies solely on the model’s pre-trained knowledge, which limits its capability to resolve complex, real-time operational issues.
  • Phase 2: Context Engineering (RAG Base)The second stage addresses the limitations of a standalone LLM by injecting trusted external data. Utilizing a Retrieval-Augmented Generation (RAG) base, the system actively retrieves specific domain knowledge—represented by the manual and database icons—to “Augment More Context.” This grounds the AI in reality, significantly reducing hallucinations and providing highly accurate, domain-specific insights.
  • Phase 3: Harness Engineering (Autonomous / Agentic)This is the ultimate target state. Moving beyond simply generating text, the AI evolves into a proactive agent. The “harness” icon symbolizes a secure, controlled framework where the AI can independently “Orchestrate Context, Tools by Process.” In this autonomous phase, the system not only understands the problem but also safely executes predefined workflows and controls physical or software tools to resolve issues with minimal human intervention.

Metric Data

Posted on by lechuck park

This image visually and intuitively defines the “6 Core Criteria of a Good Metric.” It effectively encompasses both the technical properties of the data itself and its practical value in a business context.

📊 The 6 Core Elements of a Metric

1. Data Foundation

  • Numeric: Represented by the 1 2 3 4 icon. A metric must be expressed as objective, quantifiable numbers rather than subjective feelings or qualitative text.
  • Measurable: Represented by the ruler icon. The data must be accurately collected and tracked using systems, logs, or measurement tools.

2. Data Processing

  • Changing: Represented by the refresh arrows icon. A metric is not a fixed constant; it must dynamically fluctuate over time, environments, or in response to user actions.
  • Computable: Represented by the calculator icon. You should be able to process raw data using mathematical operations (addition, division, ratios) to derive a meaningful value.

3. Business Value

  • Actionable: Represented by the hand adjusting a gear icon. A good metric should not just be “nice to know.” It must drive concrete actions, strategic adjustments, or immediate decision-making to improve a system or service.
  • Comparable: Represented by the A/B panel icon. A metric gains its true meaning when evaluated against past data (e.g., month-over-month), target goals, or different user cohorts (A/B testing) to diagnose current performance.

💡 Summary

Overall, this slide provides an excellent framework that bridges the gap between data engineering (how data is collected and computed) and business strategy (how data drives decisions). It is a highly polished visual guide for defining ideal metrics!
