I can only speak to Sun's use of uDAPL as it relates to MPI.

>From what I can tell Sun is the only group interested in the uDAPL BTL in Open MPI at this point. In contrast, Open MPI has many active members interested in the development of the OpenIB BTL which uses the user verbs protocol. Because of the community commitment Sun's MPI product based on Open MPI, ClusterTools, will also be moving away from the uDAPL BTL in favor of the OpenIB BTL. As such we expect our development of the uDAPL BTL to drop off.

This is a question for Sun to answer; they've been the primary/only drivers behind Open MPI's udapl support for quite a while.

Hi all, 

I am new to Open MPI mailing list. Just started using it for our proprietary interconnect

which uses uDAPL1.2 as underling network.

As our experience with other open source MPI2 implementation libraries, they are deprecating udapl ADI.

and giving more n more support/enhancement to gen2 ADI.

So we are thinking to move to OpenMPI, before that we want to confirm these thing with you people.
