Yes, by default, it's the current cpuset. Maybe lstopo should report the whole system (it does if you pass --whole-system), or display a clear message saying that's it's only showing the current cpuset. Apart from lstopo, for real applications, I feel like using the current cpuset only is better. By the way, we'll probably add another behavior in 1.0: only report the topology inside the current process binding mask. But for sure this behavior won't be enabled by default. Brice
