Here enP28p96s0fX devices fall under numa_node 1, which doesn't have CPUs and thus cpubind fails with "Cannot read node mask". This is expected behaviour as per numactl code working. enP32770p1s0f0 fails numactl --cpubind option with "Kernel does not know node mask". This fail is likely due to numa_node for this device having -1 as value. Any suggestions why enP32770p1s0f0 device is having numa_node value of -1 ? Is this some kernel issue here ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638515 Title: Ubuntu 16.04.1: numactl failed when trying to specify node with netdev:dev To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/numactl/+bug/1638515/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
