Subject: Re: [OMPI users] does OpenMPI started deprecating udapl support

Hi,

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.
