brl-cad is a cross-platform solid modeling system. There is one workload and it returns a single result.
Topdown profile shows a moderate retirement rate with backend stalls around 35% and frontend stalls a bit lower.
AMD metrics confirms this is on_cpu a high percentage of the time. This is floating point code with 1/5 instruction as branches.
