RE: Segmentation Fault when accessing QPN of a RC Queue pair

[Hefty, Sean]

I only looked quickly, but in main() from the links that you provided:

        ubenchIBsetQPstateRTR(&pong_as_dest, &ib_ping_qp_attr, &ping_ib_thread, 
&barg);
        ubenchIBsetQPstateRTR(&ping_as_dest, &ib_pong_qp_attr, &ping_ib_thread, 
&barg);

I noticed that you pass ping_ib_thread into the above call twice.  Is that 
intentional, or should one be pong_ib_thread?

        // At last, modify the ping QP to the Ready-to-Send state
        ubenchIBsetQPstateRTS(&ping_as_dest, &ib_ping_qp_attr, &ping_ib_thread, 
&barg);

I didn't see where you called *RTS() for pong_ib_thread.  Also, the parameters 
into *RTS() differ from those passed into *RTR() when ping_ib_thread is the 3rd 
parameter.
