Operations by Metrics

Posted on by lechuck park

1. Big Data Collection & 2. Quality Verification

  • Big Data Collection: Represented by the binary data (top-left) and the “All Data (Metrics)” block (bottom-left).
  • Data Quality Verification: The collected data then passes through the checklist icon (top flow) and the “Verification (with Resolution)” step (bottom flow). This aligns with the quality verification step, including ‘resolution/performance’.

3. Change Data Capture (CDC)

  • Verified data moves to the “Change Only” stage (central pink box).
  • If there are “No Changes,” it results in “No Actions,” illustrating the CDC (Change Data Capture) concept of processing only altered data.
  • The magnifying glass icon in the top flow also visualizes this ‘change detection’ role.

4. State/Numeric Processing & 5. Analysis, Severity Definition

  • State/Numeric Processing: Once changes are detected (after the magnifying glass), the data is split into two types:
    • State Changes (ON/OFF icon): Represents changes in ‘state values’.
    • Numeric Changes (graph icon): Represents changes in ‘numeric values’.
  • Statistical Analysis & Severity Definition:
    • These changes are fed into the “Analysis” step.
    • This stage calculates the “Count of Changes” (statistics on the number of changes) and “Numeric change Diff” (amount of numeric change).
    • The analysis result leads to “Severity Tagging” to define the ‘Severity’ level (e.g., “Critical? Major? Minor?”).

6. Notification & 7. Analysis (Retrieve)

  • Notification: Once the severity is defined, the “Notification” step (bell/email icon) is triggered to alert personnel.
  • Analysis (Retrieve):
    • The notified user then performs the “Retrieve” action.
    • This final step involves querying both the changed data (CDD results) and the original data (source, indicated by the URL in the top-right) to analyze the cause.

Summary

This workflow begins with collecting and verifying all data, then uses CDC to isolate only the changes. These changes (state or numeric) are analyzed for count and difference to assign a severity level. The process concludes with notification and a retrieval step for root cause analysis.

AI Operation: All Connected – Image Analysis

This diagram explains the operational paradigm shift in AI Data Centers (AI DC).

Top Section: New Challenges

AI DC Characteristics:

  • Paradigm shift: Fundamental change in operations for the AI era
  • High Cost: Massive investment required for GPUs, infrastructure, etc.
  • High Risk: Greater impact during outages and increased complexity

Five Core Components of AI DC (left→right):

  1. Software: AI models, application development
  2. Computing: GPUs, servers, and computational resources
  3. Network: Data transmission and communication infrastructure
  4. Power: High-density power supply and management (highlighted in orange)
  5. Cooling: Heat management and cooling systems

→ These five elements are interconnected through the “All Connected Metric”

Bottom Section: Integrated Operations Solution

Core Concept:

📦 Tightly Fused Rubik’s Cube

  • The five core components (Software, Computing, Network, Power, Cooling) are intricately intertwined like a Rubik’s cube
  • Changes or issues in one element affect all other elements due to tight coupling

🎯 All Connected Data-Driven Operations

  • Data-driven integrated operations: Collecting and analyzing data from all connected elements
  • “For AI, With AI”: Operating the data center itself using AI technology for AI workloads

✅ Continuous Stability & Optimization

  • Ensuring continuous stability
  • Real-time monitoring and optimization

Key Message

AI data centers have five core components—Software, Computing, Network, Power, and Cooling—that are tightly fused together. To effectively manage this complex system, a data-centric approach that integrates and analyzes data from all components is essential, enabling continuous stability and optimization.

Summary

AI data centers are characterized by tightly coupled components (software, computing, network, power, cooling) that create high complexity, cost, and risk. This interconnected system requires data-driven operations that leverage AI to monitor and optimize all elements simultaneously. The goal is achieving continuous stability and optimization through integrated, real-time management of all connected metrics.

Multi-Token Prediction (MTP) – Increasing Inference Speed

Posted on by lechuck park

This image explains the Multi-Token Prediction (MTP) architecture that improves inference speed.

Overall Structure

Left: Main Model

  • Starts with an Embedding Layer that converts input tokens to vectors
  • Deep neural network composed of L Transformer Blocks
  • RMSNorm stabilizes the range of Transformer input/output values
  • Finally, the Output Head (BF16 precision) calculates the probability distribution for the next token

Right: MTP Module 1 (Speculative Decoding Module) + More MTP Modules

  • Maximizes efficiency by reusing the Main Model’s outputs
  • Two RMSNorms normalize the intermediate outputs from the Main Model
  • Performs lightweight operations using a single Transformer Block with FP8 Mixed Precision
  • Generates specialized vectors for future token prediction through Linear Projection and concatenation
  • Produces candidate tokens with BF16 precision

Key Features

  1. Two-stage processing: The Main Model accurately predicts the next token, while the MTP Module generates additional candidate tokens in advance
  2. Efficiency:
    • Shares the Embedding Layer with the Main Model to avoid recalculation
    • Reduces computational load with FP8 Mixed Precision
    • Uses only a single Transformer Block
  3. Stability: RMSNorm ensures stable processing of outputs that haven’t passed through the Main Model’s deep layers

Summary

MTP architecture accelerates inference by using a lightweight module alongside the main model to speculatively generate multiple future tokens in parallel. It achieves efficiency through shared embeddings, mixed precision operations, and a single transformer block while maintaining stability through normalization layers. This approach significantly reduces latency in large language model generation.

High Cost & High Risk with AI

Posted on by lechuck park

This image illustrates the high cost and high risk of AI/LLM (Large Language Model) training.

Key Analysis

Left: AI/LLM Growth Path

  • Evolution from Internet → Mobile & Cloud → AI/LLM (Transformer)
  • Each stage shows increasing fluctuations in the graph
  • Emphasizes “High Cost, High Risk” message

Center: Real Problem Visualization

The red graph shows dramatic performance spikes that occurred during actual training processes.

Top Right: Silent Data Corruption (SDC) Issues

Silent data corruption from hardware failures:

  • Power drops, thermal stress → hardware faults
  • Silent errors → training divergence
  • 6 SDC failures in a 54-day pretraining run

Bottom Right: Reliability Issues in Large-Scale ML Clusters (Meta Case)

Real failure cases:

  • 8-GPU job: average 47.7 days
  • 1024-GPU job: MTTF (Mean Time To Failure) 7.9 hours
  • 16,384-GPU job: failure in approximately 1.8 hours

Summary

  1. As GPU scale increases, failure probability rises exponentially, making large-scale AI training extremely costly and technically risky.
  2. Hardware-induced silent data corruption causes training divergence, with 6 failures recorded in just 54 days of pretraining.
  3. Meta’s experience shows massive GPU clusters can fail in under 2 hours, highlighting infrastructure reliability as a critical challenge.
