HPC Infrastructure & Troubleshooting Handbook is a practical, operations-focused guide for engineers working with high-performance computing, AI infrastructure, Linux systems, GPUs, high-speed networking, and cluster operations.

Instead of focusing only on theory, this book shows how to approach infrastructure problems systematically — from identifying symptoms and collecting evidence to isolating faults, determining root cause, applying corrective actions, validating the result, and preventing recurrence.

Inside the book, you will learn about:

• HPC cluster architecture and infrastructure fundamentals
• Linux administration and performance troubleshooting
• CPU, memory, NUMA, and server hardware
• HPC storage architecture and storage troubleshooting
• InfiniBand, RDMA, IPoIB, RoCE, and fabric administration
• NVIDIA GPU infrastructure and GPU troubleshooting
• NVLink and NVSwitch fundamentals
• Slurm architecture, commands, scheduling, GPU scheduling, and troubleshooting
• HPC monitoring and NVIDIA UFM
• NCCL fundamentals and distributed GPU workload troubleshooting
• HPC data center operations and physical infrastructure
• Practical troubleshooting playbooks and decision-making approaches
• HPC command references and interview scenarios

The book follows a repeatable troubleshooting methodology:

OBSERVE → COLLECT EVIDENCE → ISOLATE → ROOT CAUSE → FIX → VALIDATE → PREVENT

Whether you are an HPC engineer, Linux administrator, data center engineer, AI/GPU infrastructure engineer, cluster administrator, or an engineer transitioning into HPC, this handbook is designed to help you move from understanding individual technologies to operating and troubleshooting the complete infrastructure stack.
