Coarse-grained locks, and the importance of transactions, are key concepts that motivate why Intel Transactional Synchronization Extensions (TSX) is useful. I’ll do my best to explain them in this
Intel has released details of Intel® Transactional Synchronization Extensions (Intel® TSX) for the future multicore processor code-named “Haswell”.
Intel® Software Development Emulator (released Jun 8, 2017)
Intel® Transactional Synchronization Extensions (Intel® TSX) is perhaps one of the most non-trivial extensions of instruction set architecture introduced in the 4th generation Intel® Cor
Intel® TSX exposes a speculative execution mode to the programmer to improve locking performance.. Tuning speculation requires heavily on a PMU profiler.
To use HLE/RTM to improve lock scalability the lock library needs to be enabled.

After applying a new technology (a new processor, a hardware accelerator, a new instruction, etc) besides measuring the immediate performance delta one requires a method to verify that this technol
