A test of Bayesian analysis with very high IPC and retirement rate. Also a case where my AMD chip is more than 2x faster than my Intel chip. Overall looks like half the cores are used.
Topdown metrics highlight a high retirement rate. The backend stalls are more because of CPU than memory.
AMD metrics show floating point code, and low L2 access. I expect this is a code that mostly runs inside the smaller caches.
