<div dir="ltr"><div>Hi, it seems the above error is due to the fact I don't have NUMA enabled even though half of my cores use socket 0 and half of my cores use socket 1. For some reason all the hugepage allocations are on socket 0 (it makes sense as I don't have NUMA enabled). Also I am unable to use:<br>
<br> sudo ./testpmd -c ff -n 4 -r 2 --socket-mem=1024,1024 command to allocate memory to socket 1 as it is not part of dpdk usage which is weird (do I have to have NUMA enabled to use this feature?)<br><br></div>I have two Intel quad-core Xeon 5506. I am not sure how to enable NUMA on them or if these Intel chips even support them. Does anyone know?<br>

<br></div> So far test works fine for me. However when I run testpmd, I get the following:<br>

It has 5 NICs of which two are up (eth0: BCM5716 and eth4 Intel 82598EB 10 Gigabit). Both NICs are on the same subnet before I had dpdk attach to eth4 by running the following command:<br>
