Can it be replaced with hwloc usage? thanks for the suggestion, it is genuine and useful. Following is my obse= rvations - It takes some effort to identify the NUMA with `Group` - One needs to install ` lstopo-no-graphics` on distro and manually build = and add on custom Linux. What is the output on the new AMD SKU for this command? lstopo-no-graphics --merge I have tried ` lstopo-no-graphics --merge` on a ` 2 Socket AMD EPYC 7713 64= -Core Processor` with possible NUMA
