[dpdk-users] Service cores and multi-process

Hi Harry -
Thanks.  Extending the same question further,  if two processes (within same DPDK instance) need same service, then should they both specify same service core mask?
I assumed primary process will start the service on service cores and secondary process (using same service core mask) will use the service.

No it is not required to give the exact same service-core mask.
This is the same for "normal" DPDK lcores - they can be different in the secondary than they are in the primary.
