A test of mining crypto currency algorithms. There are 11 different subtests these seem to run on all cores.
Topdown profile varies by workload but generally has a high retirement rate.
AMD metrics confirm a high retirement rate and low backend stalls. These are heavy users of floating point and have low l2 access.
