High-Performance Concurrency with HPX: Designing Scalable, Asynchronous C++ Systems for Modern Multicore and Distributed

High-Performance Concurrency with HPX: Designing Scalable, Asynchronous C++ Systems for Modern Multicore and Distributed Architectures is a practical, forward-looking guide for software engineers, system architects, and researchers who must build responsive, high-performance applications on today’s complex hardware and distributed environments. The book begins by diagnosing the limits of conventional models such as MPI and OpenMP and explains why NUMA, many-core processors, and cloud-native deployments demand a fundamentally different approach to concurrency and resource management. It positions HPX as a modern foundation for writing scalable, asynchronous C++ systems that remain robust across both single-node and distributed deployments.

At the heart of the book is a clear, hands-on exposition of HPX’s architecture and programming model: Active Global Address Space (AGAS), fine-grained user-level threads, explicit resource partitioning through thread pools and pluggable scheduling policies, and advanced execution policies that enable fine control over locality and performance. Readers are guided through idioms for asynchronous task composition, futures and continuations, parallel containers, and distributed algorithms, with practical chapters on communication patterns, synchronization primitives, and memory-management strategies—including NUMA-aware execution and distributed garbage-collection techniques—so they can write maintainable code that scales predictably.

Beyond implementation details, the book explores deployment and systems-level concerns required for production: cloud and edge orchestration, heterogeneous acceleration, network optimization for multi-tenant environments, and approaches to security and formal verification that preserve correctness at scale. Concluding chapters survey extensibility, evolving language and runtime standards, and promising research directions, making this both a hands-on manual for solving today’s performance problems and a strategic roadmap for engineers shaping the next generation of portable, high-performance C++ systems.
