Troubleshooting HPC Applications on HB, HBv2, and HC Virtual Machines

High-Performance Computing (HPC) demands optimal efficiency, but tightly coupled applications often encounter complex runtime failures and performance degradation. This course teaches you how to systematically isolate, diagnose, and resolve issues in MPI-based workloads across specialized HB, HBv2, and HC series virtual machines. What you will learn: - Understand the foundational architecture of tightly coupled HPC applications and specialized VM hardware; - Configure InfiniBand interfaces and verify low-latency network connectivity; - Diagnose common MPI runtime errors and communication bottlenecks; - Analyze performance metrics to identify CPU, memory, and storage throttling; - Apply modern observability tools to monitor cluster health and node-to-node communication; - Troubleshoot scale-out issues to ensure consistent performance across multiple nodes. You will start with key HPC terminology and foundational VM architecture concepts before moving into step-by-step diagnostic workflows. Through detailed written explanations and realistic troubleshooting scenarios, you will build a structured approach to solving complex cluster issues. This course is designed for system administrators, cloud engineers, and HPC practitioners who are new to troubleshooting tightly coupled workloads on specialized cloud VMs, with no advanced hardware background required. Start reading today to master HPC troubleshooting and keep your high-performance workloads running at peak efficiency.
