AS you guys suggested , I checked /etc/security/limits.conf file and the value was set to unlimited for both soft memlock and hard memlock. * soft memlock unlimited * hard memlock unlimited So I hope that will allow us to pin unlimited memory with kernel. I did some experiment to know how much memory is able to register successfully , and the result was approximately 128MB (127.40625 MB). Further allocation is failed by returning NULL from ibv_reg_mr, by setting errno=11 (Resource temporarily unavailable).
