Two follow-ups: - it actually works on 48 cores server and do you know why? (The problem server is 96 cores) - which part in config I need to change? (Sorry I am a noob) . Also, I am using pre-built RPM to install dpdk, do I have to rebuild the RPM on 96 cores server in order to run it on the 96 cores server?

(The problem > server is 96 cores) I think Stephen might mean your pre-build DPDK might not be built with 32 cores, I am not familiar with this neither, but I here is my grep search: /usr/src/dpdk# egrep 'CORE|CPU' x86_64-native-linux-gcc/.config CONFIG_RTE_MAX_LCORE=128 # Recognize/ignore architecture we compile for. AVX/AVX512 CPU flags for performance/power testing. CONFIG_RTE_MAX_LCORE_FREQS=64 CONFIG_RTE_TEST_PMD_RECORD_CORE_CYCLES=n I guess your pre-built DPDK might have CONFIG_RTE_MAX_LCORE built less than 96, you can either rebuilt your DPDK RPM package or rebuild from DPDK source with cores >= 96, say 128 > - which part in config I need to change?

BTW I guess "CONFIG_RTE_MAX_LCORE=128" means no more than 128 cores. But what does "CONFIG_RTE_MAX_LCORE_FREQS=64" mean?
