Sorry to come into this thread so late, but does it make sense to try the current SDP code over iWARP? As I understand things, the RDMA consortium has its own spec for SDP on iWARP, which may not precisely correspond to the IBA SDP annex. So probably the SDP code would need updating to work over iWARP.
I didn't think they were that different, but I don't know for sure. However, unless the IB-SDP uses atomics or some other IB-specific work request, it just might work.
(And don't all the iWARP vendors have TCP offload socket stuff for their adapters anyway, which is a simpler solution to the same problem that SDP solves?)
Dunno about other vendors, but Chelsio's TOE code is available on their web site (service.chelsio.com). It will be more efficient than SDP over iWARP (no SDP/iWARP headers needed).
I assume Craig is doing some research to perhaps determine exactly how SDP performs over iwarp vs TOE or standard TCP.
