Could you tell us what these commands return? ./tools/cpu_layout.py cat /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages cat /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages (assuming you have 2 NUMA nodes) Pablo > > Here is the output of the program: > > [root at test dpdk-2.0.0]# build/app/testpmd -c ff -n 4 --socket-mem=1024 > EAL: Cannot read numa node link for lcore 0 - using physical package id > instead > EAL: Detected lcore 0 as core 0 on socket 1 > EAL: Cannot read numa node link for lcore 1 - using physical package id > instead > EAL: Detected lcore 1 as core 1 on socket 1 > EAL: Cannot read numa node link for lcore 2 - using physical package id > instead > EAL: Detected lcore 2 as core 2 on socket 1 > EAL: Cannot read numa node link for lcore 3 - using physical package id > instead > EAL: Detected lcore 3 as core 3 on socket 1 > EAL: Cannot read numa node link for lcore 4 - using physical package id > instead > EAL: Detected lcore 4 as core 0 on socket 1 > EAL: Cannot read numa node link for lcore 5 - using physical package id > instead > EAL: Detected lcore 5 as core 1 on socket 1 > EAL: Cannot read numa node link for lcore 6 - using physical package id > instead > EAL: Detected lcore 6 as core 2 on socket 1 > EAL: Cannot read numa node link for lcore 7 - using physical package id > instead > EAL: Detected lcore 7 as core 3 on socket 1 > EAL: Support maximum 128 logical core(s) by configuration. > EAL: Detected 8 lcore(s) > EAL: Setting up memory... > EAL: Ask a virtual area of 0x8000000 bytes > EAL: Virtual area found at 0x7f83fae00000 (size = 0x8000000) > EAL: Ask a virtual area of 0x38000000 bytes > EAL: Virtual area found at 0x7f83c2c00000 (size = 0x38000000) > EAL: Requesting 512 pages of size 2MB from socket 0 > EAL: TSC frequency is ~2394002 KHz > EAL: WARNING: Master core has no memory on local socket! > EAL: Cannot read numa node link for lcore 0 - using physical package id > instead > EAL: Cannot read numa node link for lcore 0 - using physical package id > instead > EAL: Master lcore 0 is ready (tid=319e880;cpuset=[0]) > PMD: ENICPMD trace: rte_enic_pmd_init > EAL: Cannot read numa node link for lcore 4 - using physical package id > instead > EAL: Cannot read numa node link for lcore 5 - using physical package id > instead > EAL: Cannot read numa node link for lcore 1 - using physical package id > instead > EAL: Cannot read numa node link for lcore 1 - using physical package id > instead > EAL: Cannot read numa node link for lcore 2 - using physical package id > instead > EAL: Cannot read numa node link for lcore 3 - using physical package id > instead > EAL: Cannot read numa node link for lcore 5 - using physical package id > instead > EAL: Cannot read numa node link for lcore 6 - using physical package id > instead > EAL: Cannot read numa node link for lcore 7 - using physical package id > instead > EAL: Cannot read numa node link for lcore 2 - using physical package id > instead > EAL: Cannot read numa node link for lcore 7 - using physical package id > instead > EAL: lcore 1 is ready (tid=c1ff8700;cpuset=[1]) > EAL: lcore 2 is ready (tid=c15f7700;cpuset=[2]) > EAL: Cannot read numa node link for lcore 4 - using physical package id > instead > EAL: Cannot read numa node link for lcore 3 - using physical package id > instead > EAL: lcore 5 is ready (tid=bf7f4700;cpuset=[5]) > EAL: Cannot read numa node link for lcore 6 - using physical package id > instead > EAL: lcore 7 is ready (tid=be3f2700;cpuset=[7]) > EAL: lcore 3 is ready (tid=c0bf6700;cpuset=[3]) > EAL: lcore 6 is ready (tid=bedf3700;cpuset=[6]) > EAL: lcore 4 is ready (tid=c01f5700;cpuset=[4]) > EAL: PCI device 0000:07:00.0 on NUMA socket -1 > EAL: probe driver: 8086:10c9 rte_igb_pmd > EAL: PCI memory mapped at 0x7f8402e00000 > EAL: PCI memory mapped at 0x7f83bd5f2000 > EAL: PCI memory mapped at 0x7f84031ba000 > PANIC in rte_eth_dev_data_alloc(): > Cannot allocate memzone for ethernet port data > 8: [build/app/testpmd() [0x4285d9]] > 7: [/lib64/libc.so.6(__libc_start_main+0xfd) [0x3d18e1ecdd]] > 6: [build/app/testpmd(main+0x18) [0x42dce8]] > 5: [build/app/testpmd(rte_eal_init+0xab8) [0x4982c8]] > 4: [build/app/testpmd(rte_eal_pci_probe+0xe2) [0x4a27e2]] > 3: [build/app/testpmd() [0x491ea7]] > 2: [build/app/testpmd(__rte_panic+0xc0) [0x428520]] > 1: [build/app/testpmd(rte_dump_stack+0x1e) [0x49e91e]] > >
