Are there any applications using RDS over InfiniBand?

(1) RDS could be run over TCP on GE NIC or InfiniBand HCA, how to using it with these different underlying hardware based on MLNX_OFED?

(2)  For an application written with the traditional sockets, how to translate or port it with RDS over IB? Is there any user shared library to pre-load RDS protocol without code recoding and recompiling of the existing applications, just like libsdp.so?

(3) How to compare and  benchmark the performance between UDP over GE and RDS over IB, including network rate, TPS and transport latency?

Thanks for your attention.
