Hi The rte_mempool and rte_ring libs have multi-producer/multi-consumer versions. But it's also mentioned in the header files that the implementation is not pre-emtable : " Note: the mempool implementation is not preemptable. A lcore must not be interrupted by another task that uses the same mempool (because it uses a ring which is not preemptable)"
I had some questions on the same : - Does having mutually exclusive core masks for a set of threads which use the ring/mempool suffice for thread safety ( threads will have different core ids but they will not be pinned to cores) ? - If i want to use this data structures in a pthread ( created outside of DPDK environment), is it ok to use this if i do "RTE_DEFINE_PER_LCORE(unsigned, _lcore_id);" with a core_id exclusive of all other core masks for DPDK processes. -Jyoti
