OpenMPI Programming and Architecture by Richard Johnson

"OpenMPI Programming and Architecture"

Delve into the intricacies of high-performance computing with "OpenMPI Programming and Architecture," an authoritative guide that bridges theoretical principles with practical, hands-on expertise. The book opens with a rigorous exploration of parallel computing models, memory architectures, and foundational laws of scalability, providing readers with a deep understanding of the essential frameworks underpinning distributed computation. With a comprehensive analysis of the evolution of the MPI standard and its profound impact on modern supercomputing, this work situates OpenMPI at the center of current and future advancements in parallel processing.

The volume proceeds to demystify the sophisticated internals of OpenMPI, methodically dissecting its layered system architecture and modular component model. Chapters lead the reader through crucial elements of OpenMPI’s runtime, including resource management, data movement, threading, error handling, and advanced communication patterns. Practical sections offer nuanced guidance on using the core MPI programming API, implementing efficient synchronization, constructing virtual topologies, tuning for performance, and handling fault tolerance—a toolkit indispensable for both novice programmers and seasoned HPC developers aiming to extract maximum performance at scale.

Building on this solid foundation, the book ventures into advanced and emerging domains, from hybrid programming with GPUs and accelerators to orchestrating MPI workloads in cloud, containerized, and multi-tenant environments. Illustrated case studies and real-world production stories illuminate the far-reaching applications of OpenMPI, while forward-looking discussions address resilience, MPI standardization, evolving hardware, and integration with big data and workflow engines. Rounded out with chapters on extensibility, open-source contribution, and future research opportunities, "OpenMPI Programming and Architecture" is an essential reference for practitioners and researchers charting the next era of scalable, robust parallel computing.
