说明
lstopo-no-graphics displays the hardware topology of the system in text format without requiring a graphical display. Part of the hwloc (Hardware Locality) package, it shows the hierarchical structure of CPUs, caches, memory, and I/O devices. The output shows the system's NUMA nodes, packages (sockets), cores, and processing units (hardware threads) in a tree structure. This information is useful for understanding CPU architecture, cache sharing, and memory locality for performance optimization. Unlike lstopo, this variant works in console-only environments without X11 or graphical libraries.
