Problem-solving in High Performance Computing: A Situational Awareness Approach with Linux

Problem-Solving in High Performance Computing: A Situational Awareness Approach with Linux focuses on understanding giant computing grids as cohesive systems. Unlike other titles on general problem-solving or system administration, this book offers a cohesive approach to complex, layered environments, highlighting the difference between standalone system troubleshooting and complex problem-solving in large, mission critical environments, and addressing the pitfalls of information overload, micro, and macro symptoms, also including methods for managing problems in large computing ecosystems. The authors offer perspective gained from years of developing Intel-based systems that lead the industry in the number of hosts, software tools, and licenses used in chip design. The book offers unique, real-life examples that emphasize the magnitude and operational complexity of high performance computer systems. Provides insider perspectives on challenges in high performance environments with thousands of servers, millions of cores, distributed data centers, and petabytes of shared dataCovers analysis, troubleshooting, and system optimization, from initial diagnostics to deep dives into kernel crash dumpsPresents macro principles that appeal to a wide range of users and various real-life, complex problemsIncludes examples from 24/7 mission-critical environments with specific HPC operational constraints
