An acoustic modeling program with five workloads. Mostly keeps the CPU busy and runs with all cores.
Topdown metrics. Largest share is backend stalls and not many frontend stalls to make a moderate retirement rate.
AMD metrics show floating point code with not many L2 accesses and a low number of branches.
