With this, each L3 cache will not be reported as a NUMA domain (/NUMA node). Thank you!

If I change the NPS (numa per socket) in BIOS and power cycle the system and the I launch a DPDK application, I always get this message: EAL: Detected CPU lcores: 128 EAL: Detected NUMA nodes: 16 NPS is able to change the number of NUMA but DPDK always detects 16 NUMA domains. I tried with NPS1, NPS2, NPS4. [-- Attachment #2: Type: text/html, Size: 4767 bytes --]
