By now, many of you have heard of Intel® Transactional Synchronization Extensions (Intel® TSX).

How to printf inside (aborted) Intel® Transactional Synchronization Extensions (Intel TSX) transactionsOne of the most popular ad-hoc functional debugging techniques is to use the printf or fprintf functions to display the state of variables. However, if these functions are used inside an Intel® TSX transaction they can cause transaction aborts. The reason is that flushing the print output buffer involves an operating system call and an I/O operation: operations that cannot be roll backed by Intel...
Intel has released details of Intel® Transactional Synchronization Extensions (Intel® TSX) for the future multicore processor code-named “Haswell”.
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® 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 recently released the 4th Generation Intel® Core™ processors, which have Intel® Transaction

Using Intel® TSX with VTune(TM) Amplifier XE 2015 Beta to measure transaction time & abort in your code?
When the user develops multithreaded applications, the user should protect critical (sensitive) code area called by threads, so threads access shared memory without data conflict.
Intel® TSX exposes a speculative execution mode to the programmer to improve locking performance.. Tuning speculation requires heavily on a PMU profiler.
