We would like to add SDP support for OPENMPI.
SDP can be used to accelerate job start ( oob over sdp ) and IPoIB performance.
I fail to see the reason to pollute the TCP btl with IB-specific SDP stuff.For the oob, this is arguable, but doesn't SDP allow for *transparent* socket replacement at runtime ? In this case, why not use this mechanism and keep the code clean ?
