Open source library for quantitative finance written in C++. Two workloads, the first runs on all 16 cores and the latter is only two cores (listed as single-threaded).
This code has a high retirement rate and a low number of frontend stalls.
AMD metrics show on average we run on half the cores with a moderate amount of floating point, not many L2 misses and a high retirement rate.
