I have been using this DAPL provider with my testing of MPI and
it seems stable. It has been tested up to 128 nodes.
The uAT version on the other hand seems to still have problems
so I would be glad to see this version be put into the tree also. 

Sayantan, you may also want to try this socket based CM 
uDAPL provide for your work. It seems more stable than the uAT version
in my testing thus far.
