Multicore Synchronization - The Lesser-Known Primitives

Explore advanced multicore synchronization primitives in this 46-minute conference talk from C++Now 2017. Delve into lesser-known synchronization mechanisms and their performance properties, with a focus on practical challenges faced by engineers implementing them. Learn about load-linked store conditional operations, pause instructions, prefetching, various lock types including spinlocks and scalable locks, and safe memory reclamation techniques. Examine performance comparisons, latency considerations, and runtime behavior of different synchronization approaches. Gain insights from real-world examples drawn from the Concurrency Kit project, used in mission-critical systems processing billions of transactions daily. Discover resources for further study and open-source implementations to enhance your understanding of complex concurrent systems in C++.
