Ken,
At UTK we focus on developing two generic frameworks for scalable fault
tolerant approaches. One is based on uncoordinated checkpoint/restart while the
other is application level.
1) uncoordinated C/R based on message logging. Such approaches are fully
automatic, rely on an external check
Thanks. I've read your (Joshua Hersey's) Ph.D. thesis on fault
tolerance using checkpointing with much interest. It would be of further
interest to get the range of possible user requirements for defining the
behaviors in response to various faults.

The MPI forum is in the process of fefining this - the work going on at ORNL is
in this context.

Quite a bit of capability is already in the trunk, but there is always
more to do :-)
