Real Time Engineering High Performance Systems by Valdes James (2 results)

Taschenbuch. Condition: Neu. Neuware - Imagine this: You have just deployed a brilliantly structured, logically flawless C++ algorithm. The unit tests are green. The architecture is clean. But in production, a random 10-millisecond latency spike costs your high-frequency trading firm a million dollars. Or worse, it causes the sensor fusion node in an autonomous vehicle to miss a critical braking deadline.I have been there. You stare at the profiler, wondering why a system that is fast 99% of the time suddenly choked. The terrifying truth The operating system lied to you. The compiler quietly deleted your code. The CPU's branch predictor guessed wrong, flushing its entire pipeline. In this book, I will take you into the microscopic, atomic reality of the machine. I will show you exactly where those missing nanoseconds went, and more importantly, how to take them back.What's inside- Defeating the Compiler: Learn how to write rigorous microbenchmarks using Google Benchmark that prevent the LLVM optimizer from faking your execution times.- Hardware Interrogation: Use Linux perf and Intel VTune to read raw CPU performance counters, tracking cache misses and instruction stalls directly from the silicon.- Kernel Bypass & Networking: Discover how High-Frequency Trading (HFT) engines bypass the OS entirely to read network packets straight off the fiber optic NIC.- Data-Oriented Design: Master memory layouts (Structure of Arrays) to perfectly pack the CPU's L1 cache and unleash SIMD vectorization.- Taming the Tail: Measure and flatten 99.99th percentile latency spikes using HDR Histograms and strict OS isolation.Who it's meant forThis book is crafted for mid-level to senior C++ developers, systems architects, quantitative developers, and robotics engineers who can no longer afford to guess about performance. If your software operates in environments where missing a deadline means financial ruin or physical danger-whether in HFT, self-driving cars, game engine development, or telecom-this book is your blueprint.Stop guessing how the machine works and start commanding it. The difference between standard software and world-class engineering is measured in nanoseconds. Grab your copy today, look under the hood of your hardware, and write C++ that absolutely dominates the silicon.…
