-#+END_SRC
-
-The command will scan the host to find the NUMA nodes, and all the PCI devices, and map the PCI devices back to the NUMA node.
-
-It also provides a way to see the list of CPUs attached to the node.
-
-* Limitations
-** Device class
-For now only the following classes of hardware are cared for:
-- NVMe
-- network
-- GPU
