Hi Folks,

Here’s the list of mpi opaque objects and a few additional constructs for

consideration of states in the presence of process failures:

communicators – Aourelian, Wesley

groups -  Rich G.

data types - Sayantan

RMA windows – Howard

files (file handles) – Darius B.  

info object  - Darius

error handler - Darius

message obj. – David S.

request - Manjo

status - Manjo

op  - Darius

port (mpi-2 dynamic) – David S.

user buffers attached to MPI for bsends - Sayantan

Need to define lifecycle of the object in the case of no process failures,
and in the case when one or more process failures occur while the
object exists.
