Hi,
I think this is related to how to use RDMA. I strongly suggest to read this document http://www.mellanox.com/related-docs/prod_software/RDMA_Aware_Programming_user_manual.pdf at first.
In a short reply:
- What is qps ?
- qps are connections between different nodes.
- get_local_attr get local QP's attribute.
- It is called when a remote QP wants to connect( to this local QP).
3.The connections are established in change_qp_states().
Thanks.

感谢您的回答,我的RDMA网络是RoCE的,在源代码基础上做了调整,RDMA write时poll阶段报错“got bad completion with status: 0xc, vendor syndrome: 0x81, with error transport retry counter exceeded, qp n:1 t:0
”,请问你们有遇到过这一问题或者知道该如何解决吗?

我看了一下你们是改用了rdma_cm重写了这一模块是吗,我还是在你们原来libib的基础上加了gid,代码能运行到poll这里是不是说明connection已经成功了呢,有做网络的同学建议过我抓包看看数据是否异常,ibststus的输出您指的是什么呢?wc的status是IBV_WC_RETRY_EXC_ERR

ibstatus和ib_send_bw的输出情况如下,目测没什么问题:

嗯嗯我也发现我昨天看错了,那我直接用你们的新lib好了,谢谢你啦

请问query分发在代码中只体现了按照subject分发,没有object和predicate的分类吗?是与论文中所写不同还是我漏看了哪里?烦请指教。

Please open a new issue.
