The smt_pause() operation may be useful in spin loops to release CPU resources for use in simpling threads on SMT-capable CPUs. Compared to the previous pause() implementation, added support for PowerPC and Solaris and use isb instruction on AArch64, which seems to be used in various open source projects instead of yield.
Boost.Atomic, part of collection of the Boost C++ Libraries, implements atomic operations for various CPU architectures, reflecting and extending the standard interface defined in C++11 and later.
