Let's say I have a 4 lcore machine (2 phys. cores with HT) and I want to run 7 threads on it. I thought that these options would help me: -c 0xf -l 0-6 --lcores='0,(1,3)@2,(2,4)@3,(5,6)@1' But all I am getting is "EAL: invalid parameter for --lcores". So my question is - how can I tell EAL to start 7 threads, pin them to given CPUs and made them accessible as lcores for issuing rte_eal_remote_launch? Thanks in advance, Martin
