Open MPI actually supports m
As far as PCIe, I am looking into:
1. Dolphin's implementation of IPoPCIe 2. SDP protocol and how it can be
utilized, mapping TCP to RDMA
Not sure if the only answer for this is a custom stack, API/kernel module.
Do you have any input on the above mentioned things?

If it provides a TCP stack and an IP interface, you should be able to use Open
MPI's TCP BTL interface over it.

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

You should use a "native" interface to your RDMA network instead (which one
you use depends on which kind of network you have).
I have a rather naive fo
