RHOSP 16.1.2 introduces a technology preview of the AMD EPYC 2 (Rome) platform with the UEFI setting `NPS` (Numa Per Socket)` set to `1`.
+
Other values of `NPS` (2 or 4) are used in DPDK benchmarks to reach the platform peak performances, without OpenStack, on bare metal.
+
Red Hat continues to evaluate the operational trade-off of `NPS=2` or `NPS=4` with OpenStack. This configuration exposes multiple Numa nodes per socket.
