Subject: [dpdk-users] How to using add/lookup hash table in multithread environment
Date: Fri, 5 May 2017 09:32:24 +0700 (ICT) [thread overview]
Message-ID: <bf125e83-755c-be2e-4e49-4caba9282519@viettel.com.vn> (raw)
Hi DPDK team,
I am using DPDK to build a program in multithread environment.
I use 1 thread (on 1 core) to add and delete hash table key ( by
rte_hash_add_key() and rte_hash_del_key() function); And use 8 thread
(on 8 others core) to lookup (by rte_hash_lookup() function ).
As I know, rte_hash_lookup() function is /multi-thread safe,/ and
te_hash_add_key() and rte_hash_del_key() function is not /multi-thread
safe/.
So: Do I need using /lock/ when I add or delete key by 1 thread while 8
others thread is looking-up?
Many thanks,
Vuong Le
