A deep dive into analytic number theory, Lehmer’s formula, and L3 cache pinning in handwritten LLVM IR.Sat, 30 May 2026 00:00:00 GMTnumber-theoryprime-numbersllvmllvm-irmathematicslehmer's-algorithmsystems-programmingbare-metaloptimization-algorithmsdynamic-programmingalgorithmsperformanceassemblyhttps://0bvdnt.github.io/blogs/cpp-concurrency-evolution-11-to-26/https://0bvdnt.github.io/blogs/cpp-concurrency-evolution-11-to-26/For decades, writing safe, high-performance concurrent C++ required navigating a minefield of platform-specific APIs and undefined behavior. This article provides an exhaustive examination of the standard's solution, tracing the language's evolution from C++11's foundational thread-and-mutex primitives to the composable, zero-overhead asynchronous execution models of C++26. Dive into a rigorous taxonomy detailing the theoretical underpinnings of thread-level parallelism, stackless coroutines, portable SIMD, and the forthcoming sender-receiver framework for modern systems programming.Sun, 08 Mar 2026 00:00:00 GMTC++modern-C++parallelismconcurrencyasynchronous-programmingsystems-programmingsoftware-architecturemultithreadingcoroutinesSIMDsender-receiverlock-free-programmingC++11C++14C++17C++20C++23C++26
