The Intel® Compilers in version 2024.0 and newer can use Hardware PGO (HWPGO), which is Intel’s sample-based profile-guided optimization (SPGO). HWPGO is an alternative to traditional instrumented PGO which leverages hardware performance monitoring counters available on modern Intel CPUs. Using HWPGO is a lower overhead, faster, and more efficient way to establish a performance optimization profile for your primary workload execution path.
For more details including how to use HWPGO with an example, please check this post: https://www.intel.com/content/www/us/en/developer/articles/technical/hwpgo.html
