I think you want to set up three independent compounds, like in
hactar.rc.eqc. Maybe you'll find it easier to use a projection instead of a
wall to configure your overlapped setup. I don't think you need input and
output frames.

On the control host I would just use a fourth channel with a symmetric wall.

As for the hang, a stack trace would be most helpful.

IP-over-IB is a precondition to SDP. If you don't use LD_PRELOAD, you most
likely have IP-o-IB. You can verify your performance using the netperf tool
shipping with Equalizer (see IB doc on website for details), with SDP you'll
get much better performance.
