i do not think the OMPI TCP BTL *explicitly* passses the SDP socket type
when creating sockets.
and though i did not try that, i suspect using SDP via an LD_PRELOAD'ed
library would be enought to use SDP sockets
Cheers,

2. SDP protocol and how it can be utilized, mapping TCP to RDMA
I don't think the Open MPI TCP BTL will pass the SDP socket type when creating sockets --
SDP is much lower performance than native verbs/RDMA. You should use a
"native" interface to your RDMA network instead (which one you use depends on
which kind of network you have).
