Hi Jyoti,

You must carefully analyse your usecase.
Typically each core must run a tight loop (and therefore one thread spawned=
 by remote launch) which does a while 1 { get packet, service packet }
You should try to build your application around the above paradigm.

One of your cores can service the slow path using traditional linux with a =
tap interface.

Regards
-Prashant

Subject: [dpdk-dev] query about rte_eal_mp_remote_launch()

Hello Devs
I'm new to DPDK and trying to understand the basics..
I want to write a DPDK app where I want to configure shm rings on the fly, =
and I want one thread(per core) to service the ring.
In some of the examples I saw rte_eal_mp_remote_launch() being used, but th=
is is a one time launch. Can I use pthread_create() on-the-fly (taking care=
 of CPU core allocation), after doing an initial threads launch using rte_e=
al_mp_remote_launch()?
 Thanks
Jyotiswarup Raiturkar
