Related Work

This repository sits between a teaching guide, an executable notebook, and an archive-ready maintenance artifact. The works below matter because they illuminate one of those three roles.

Measurement and profiling infrastructure

Work	Type	Why it matters here	How this repository differs
Google Benchmark	public repository and benchmarking library	many example benchmarks in the C++ ecosystem use its fixture and reporting model	this repository uses benchmark executables as evidence, but the project itself is not a benchmark framework
Brendan Gregg's FlameGraph	public repository and methodology	underpins the flamegraph workflow referenced from tools/performance/ and profiling docs	this repository teaches when to use flamegraphs, not how to maintain the tooling itself
perf wiki	official project documentation	frames the Linux-first counter and sampling workflows used in the playbook	this repository narrows the guidance to concrete example workloads
Intel VTune Profiler	vendor tool documentation	represents the more detailed vendor-grade profiling path for Intel targets	VTune is discussed as an escalation path, not as a required dependency

SIMD and low-level optimization references

Work	Type	Why it matters here	How this repository differs
xsimd	public repository and SIMD abstraction library	shows one mature approach to portable SIMD wrappers in modern C++	this repository keeps a smaller teaching wrapper to expose the trade-off directly
Agner Fog optimization manuals	manuals and articles	provide the microarchitectural background for instruction throughput, latency, and CPU behavior	the repository turns those ideas into small runnable examples rather than exhaustive architecture catalogs
Intel 64 and IA-32 Architectures Optimization Reference Manual	vendor optimization manual	useful when interpreting SIMD and cache-sensitive results on Intel hardware	the repository stays vendor-neutral in structure and uses Intel material as one authoritative source among several
Compiler Explorer	public tooling site	invaluable for checking generated code and vectorization decisions	the repository keeps assembly inspection adjacent to, but separate from, local benchmark evidence

Concurrency and industrial C++ infrastructure

Work	Type	Why it matters here	How this repository differs
oneTBB	public repository and tasking library	a reference point for scalable parallel patterns and production-grade scheduling	this repository teaches fundamentals such as atomics, queues, and OpenMP rather than adopting a full task runtime
folly	public repository	demonstrates high-performance data structures and systems-oriented utility design at production scale	this repository favors small, inspectable teaching examples over large utility surfaces
Abseil C++	public repository	useful as a contrast in API design, portability, and low-level utility engineering	the repository is a guide with examples, not a broad dependency library
C++ Core Guidelines	living guideline set	supplies durable language and design guidance that complements performance work	the repository focuses on measurable performance topics, not the full range of C++ design guidance

Algorithms and hash table implementations

Work	Type	Why it matters here	How this repository differs
ska::flat_hash_map	public repository	a teaching-sized Robin Hood hash map with clear source code; directly comparable to the repository's hash-table examples	the repository adds benchmark methodology, cache-miss analysis, and explicit trade-off documentation
tsl::robin_map	public repository	another Robin Hood implementation with emphasis on API compatibility and hash customization	the repository focuses on the underlying algorithmic and cache-behavior decisions rather than API completeness
Abseil flat_hash_map	public repository	the industry standard for Swiss Table / F14 group-probing hash tables	the repository uses Swiss Tables as a performance target and explains why group probing wins on modern CPUs
Sedgewick & Wayne, Algorithms	textbook	the canonical modern reference for sorting, searching, and graph algorithms	the repository narrows to performance-relevant details (cache behavior, SIMD opportunities, branch prediction) and keeps everything executable
Knuth, TAOCP Vol. 3	textbook	definitive analysis of sorting and searching	the repository translates Knuth's analytical insights into measured C++ implementations with perf output

What this comparison clarifies

Taken together, these works show what this project is trying to be:

• not a replacement for production utility libraries such as oneTBB, folly, or Abseil
• not a standalone benchmarking or profiling tool
• not a generic language tutorial divorced from executable evidence
• not an exhaustive algorithms textbook, but a performance-engineering lens on algorithm selection and implementation
• instead, a compact performance-engineering guide that keeps its claims close to code, validation, and public references

That narrower scope is part of the repository's long-term maintainability story.
