I changed the .config file setting CONFIG_RTE_MAX_LCORE to 256, and rebuilt dpdk and libmoon. Now I can get 256 lcores running hello world example of DPDK:

But when I run the libmoon hello world example, there is only 128 lcores(I put in some print functions to learn how it works, please ignore them):

How can I change that?

    libmoon expects CONFIG_RTE_MAX_LCORE=128 (and tries to use the last cores for our shared tasks), however, you should be able to change that to 256 here: https://github.com/libmoon/libmoon/blob/master/lua/dpdk.lua#L160
