Trex can't allocate hugepages with Sub-NUMA clustering enabled, no issues if I disable the SNC in the BIOS. Likely to be related to https://groups.google.com/g/trex-tgn/c/F_BSC4c4VxA, was it really fixed?
Here is the output from my system, trex command is shown the last. Tested with v3.03 and v3.04.
