Subject: [dpdk-dev] How to using add/lookup hash table in multithread environment
Date: Fri,  5 May 2017 09:51:58 +0700 (ICT)	[thread overview]
Message-ID: <874b0c85-f02e-1fb9-c648-1f0570d92db2@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
