Re: [ewg] Automated Port Migration on RC connected QPs

Hi Sean,

One of our developers created a code example to do APM between ports on an
HCA. This code is available in Section 8.1 of the Mellanox RDMA Aware
Programming User Manual which is available here:

Thanks

Rupert

The RDMA CM does not support APM.  You could use the RDMA CM to connect, but
would need to exchange alternate path information in band and modify the QP
directly to set the alternate path information and APM state.

[ewg] Automated Port Migration on RC connected QPs

2013-05-02 Thread Sean T Price 


Does anyone have example code on how to setup automatic port migration
correctly for RC connected QPs that use RDMA CM?

Is there any documentation or guidance on the subject of APM setup?

Any pointers would be appreciated.

Sean
