Good morning,
I want to evaluate DPDK on my servers, which are equipped with 4 Mellanox ConnectX-5 Ex 2x100G cards.
I have installed MLNX_OFED 5.3-1.0.0 from nvidia, compiled from source with `--upstream-libs --dpdk` flags.
I downloaded DPDK 20.11 LTS and compiled following the quick start guide.
I have allocated 1024 2MB hugepages for each NUMA node.
When I try to run dpdk-helloworld I get:
```
[aperro@ebstortest02 examples]$ sudo ./dpdk-helloworld
EAL: Detected 64 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: No available hugepages reported in hugepages-1048576kB
EAL: Probing VFIO support...
EAL: VFIO support initialized
EAL: DPDK is running on a NUMA system, but is compiled without NUMA support.
EAL: This will have adverse consequences for performance and usability.
EAL: Please use --legacy-mem option, or recompile with NUMA support.

Hello Alberto,
Is this a specific issue with the helloworld?
Does testpmd work ok for you?
Regards,
Asaf Penso
