A C++ library of cryptographic algorithms. There are three subtests. These are single-threaded
Topdown profile shows some blurring over time with sections of strong branch misses and other sections with high retirement rates.
AMD metrics show a composite of time above with a high retirement rate, very low L2 access and moderate floating point.
