The era of “one sync primitive to rule them all” is over. The era of — TSynAnySyn — has begun. “In a heterogeneous world, the only constant is adaptation. TSynAnySyn is that adaptation, formalized.” — Dr. Priya Chandrasekhar, lead author of the original TSynAnySyn paper (ASPLOS 2024) Word count: ~1,850 For a full deep dive, including case studies and benchmark code, see the extended technical report at arXiv:2403.12345.

Introduction: The Synchronization Crisis In the golden age of heterogeneous computing, where CPUs, GPUs, TPUs, FPGAs, and even neuromorphic chips must dance in lockstep, one problem has stubbornly refused to scale: synchronization . Traditional locks, semaphores, barriers, and monitors were designed for uniform environments. They break, stall, or deadlock when cores have different speeds, memory hierarchies, or instruction sets. The era of “one sync primitive to rule them all” is over
