In my previous blog, I discussed “Ways to Speeding up Your Cloud Environment
(This work was done by Vivek Lingegowda during his internship at Intel.)
Most multi-threaded software uses locking. Lock optimization traditionally has aimed to reduce lock contention, that is make the critical regions smaller.
Intel® TSX exposes a speculative execution mode to the programmer to improve locking performance.. Tuning speculation requires heavily on a PMU profiler.
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
By now, many of you have heard of Intel® Transactional Synchronization Extensions (Intel® TSX).
