However, the code becomes quite complicated to read with if state= ments within RTE_LCORE_FOREACH_SLAVE(), to break the loop (since not all slave co= res are checked for). This is a snip from test_hash_multi_add_lookup(): /* snip */ RTE_LCORE_FOREACH_SLAVE(core_id) { if (i < rwc_core_cnt[n]) rte_eal_remote_launch(test_rwc_reader, (void *)(uintptr_t)read_type, core_id); else if (i >=3D rwc_core_cnt[n] && i < (rwc_core_cnt[n] + rwc_core_cnt[m])) { rte_eal_remote_launch(test_rwc_multi_writer, (void *)(uintptr_t)pos_core, core_id); pos_core++; } else break; i++; } >=20 > --=20 > David Marchand
