[dpdk-dev] Issues with running multicore

Hi All,
Iam trying to create multi core application by mapping separate function for each core.
I had followed Multi process example and I had used pthread.
The use case is:
1. In a single process, launch pthread and run rte_eal_init
2. Once rte_eal_init is done, create 3 pthreads
3. Launch master core.
4. In each of 3 pthread, launch slave core.
The issue is, I don't see 4 cores running. Instead I see only single core running.
Here is the Pseudo code:
Init_pmd{
ret = rte_eal_init(args, argv) ==> I had set the number of cores to 4 in the params.
pthread_create(&thread1, NULL, (void*)threadFun1, NULL);
pthread_create(&thread2, NULL, (void*)threadFun2, NULL);
pthread_create(&thread3, NULL, (void*)threadFun3, NULL);
rte_eal_mp_remote_launch(launch_pmd_single_lcore, NULL, CALL_MASTER);
}
Iam mapping each core to threadFun1, threadFun2 and threadFun3.
threadFun1
{
RTE_LCORE_FOREACH_SLAVE(lcore_id)
{
if( lcore_id == 1 )
rte_eal_remote_launch(threadFun1_launch_one_lcore, NULL, lcore_id);
}
}
Has anyone seen this issue?
Please let me know if iam missing something?
Thanks
Jaffar
