Advanced Low-Latency C++ Programming

This advanced course is designed for experienced C++ developers building ultra-low-latency systems, such as high-frequency trading engines, real-time communications, or custom networking stacks. It explores architecture-aware programming, lock-free algorithms, memory and I/O optimizations, compiler-level tuning, and kernel bypass techniques. Participants will learn to push performance boundaries while maintaining system stability and determinism under extreme load conditions.

Course Duration:

56 hours

Level:

Advanced

Objectives:

By the end of this course, participants will be able to:

  • Design CPU- and cache-aware C++ applications for predictable latency.

  • Implement advanced memory strategies with custom allocators and huge pages.

  • Leverage SIMD intrinsics and compiler optimizations for critical paths.

  • Build and debug lock-free, wait-free concurrent systems.

  • Interface with kernel bypass frameworks (DPDK, RDMA, io_uring) for zero-copy I/O.

  • Diagnose and eliminate tail-latency issues using hardware and software profiling tools.

  • Develop real-time systems that meet sub-microsecond latency budgets.

Prerequisites:

  • Strong C++ proficiency (C++14/17/20), including memory management and multithreading.

  • Prior experience with low-latency or performance-critical systems.

  • Familiarity with Linux system programming (e.g., mmap, epoll, sched_setaffinity).

  • Comfortable with tools like perf, valgrind, gdb, or similar profilers.
