3.1 Chapter 1: The OS Dilemma in the AI Era

Target Audience: CTOs shocked by GPU bills

• GPU utilization rates low enough to run a marathon
• The need for OS-level optimization magic in the age of large models
• Domestic hardware adaptation becomes a new necessity

Real-World Story

Last Singles’ Day, a live streaming platform’s technical director received a financial alert: their GPU cluster had been at 90% capacity for three weeks, yet AI recommendation system latency kept increasing. Investigation revealed: traditional Linux scheduling created GPU memory fragmentation – like a packed subway train where sitting, standing, and doorway passengers all consume resources inefficiently.

3.2 Chapter 2: TencentOS’s AI Acceleration Trifecta

Target Audience: Algorithm engineers focused on performance gains

3.2.1 The Secret Sauce of OS+AI Fusion

Traditional operating systems treat GPUs as “dumb memory,” while TencentOS embeds GPU virtualization directly into the kernel. Think of it as assigning a dedicated “memory管家” to each AI task, monitoring tensor lifecycles in real-time.

3.2.2 The Magic of Four-Layer Caching

# Recommendation system optimization comparison
Before: 45GB embedding loaded from cloud storage per inference
After: 83% requests hit local SSD cache, latency drops from 1200ms→89ms

3.2.3 Real-World Case: Image Generation Speed Doubled

A game company using TencentOS achieved:

• Stable Diffusion image generation time reduced from 4.2s/image to 1.8s/image
• Key optimizations:

  1. 显存预分配策略 (显存预分配策略)
  2. CUDA kernel targeted optimizations
  3. Dynamic compute scheduling algorithms

3.3 Chapter 3: Hands-On qGPU Virtualization

Target Audience: Cloud engineers needing resource multiplexing

3.3.1 Three Steps to Virtual GPU Creation

# 1. Check available GPUs
$ qgpu-cli scan
[INFO] Detected 2x NVIDIA A100 80GB

# 2. Create virtual instance
$ qgpu-cli create \
  --name llm-inference \
  --gpu 0 \
  --compute 35% \
  --memory 24GB \
  --isolated

# 3. Verify allocation
$ qgpu-cli list
┌─────────────┬─────────────┬───────────────┐
│ Virtual GPU │ Physical    │ Compute       │
│ ID          │ Device      │ Allocation    │
├─────────────┼─────────────┼───────────────┤
│ vgpu-123    │ 0           │ 35% (28 TFLOPS)│
│ vgpu-456    │ 0           │ 40% (32 TFLOPS)│
└─────────────┴─────────────┴───────────────┘

3.3.2 Hybrid Deployment Success Story

A cloud platform achieved:

• Online inference: 30% compute + 20% memory
• Offline training: 60% compute + 75% memory
• Reserved capacity: 10% for burst needs

Result: 2.3x monthly revenue per GPU, 40% reduction in hardware procurement

3.4 Chapter 4: The Art of FlexKV Caching

Target Chapter: Embedded in Practical Chapter

3.4.1 Four-Layer Cache Logic

graph TD
    A[AI Request] --> B{Memory Hit?}
    B -->|Yes| C[Direct Return]
    B -->|No| D{Memory Cache?}
    D -->|Yes| E[Load to VRAM]
    D -->|No| F{SSD Cache?}
    F -->|Yes| G[Load to Memory]
    F -->|No| H[Cloud Storage Read]

3.4.2 Parameter Tuning Tips

# Adjust cache policy (place in practical chapter)
$ flexkv-config set policy=LRU
$ flexkv-config set ssd_capacity=200GB

3.5 Chapter 5: RHEL Migration Secrets

Target Audience: Ops teams anxious about CentOS EOL

3.5.1 Migration Tool Guide

# 1. Pre-check (place in advanced chapter)
$ tencentos-migrate check \
  --source /etc/centos-release \
  --target /etc/tencentos-release

# 2. Execute migration
$ tencentos-migrate start --auto-rollback

# 3. Verify results
$ tencentos-migrate verify
[SUCCESS] 237/237 packages compatible

3.5.2 Financial-Grade Validation Standards

3.6 Chapter 6: The Domestic Hardware Ecosystem

Target Audience: Tech decision-makers focused on self-reliance

3.6.1 Hardware Support Overview

3.6.2 Loongson Adaptation Case Study

A government cloud achieved:

• Loongson 3A5000 + Ascend 910B combination
• 85% of NVIDIA V100’s deep learning training performance
• Full self-reliance in critical algorithms

4. Required Example

# Practical Chapter Example: qGPU Resource Allocation
# Input command (place in practical chapter)
qgpu-cli create --name llama2 --gpu 0 --compute 40% --memory 60%

# Output result
{
  "id": "vgpu-123",
  "compute_alloc": "40%",
  "memory_alloc": "24GB/40GB",
  "status": "active"
}

# Expected outcome: Single A100 simultaneously runs 2 different AI workloads
