Ah. Shows how much I know. :-)
Is there any way to make
I also believe that for iWARP and RoCE, the RDMA CM will be chosen
automatically, and UD CM will be automatically chosen for IB.
[Josh] If you want to run OMPI over RoCE on Mellanox hardware, you must
explicitly choose rdmacm with -mca btl openib,sm,self -mca

Technically you may setup RoCE connection without RDMA CM.

Thanks Jeff. But I'm already offline today ...
I can not confirm it until monday morning, sorry.

I just created a new nightly tarball that includes all of those CMRs:
1.8a1r31269. It should have the fix for this error included in it.

More specifically, RoCE QPs can only be made using the RDMA connection manager.

Thanks Jeff. It seems to be really the latest one - ticket #4474.

Hi all,
I saw this error as shown below with openmpi-1.8a1r31254.
I've never seen it before with openmpi-1.7.5.
The message implies it's related to vader and I can stop
it by excluding vader from btl, -mca btl ^vader.
Could someone fix this problem?
