Yo all

As part of the ORTE discussions that took place today, it was mentioned that
we would be modifying the hostfile behavior to support several user requests
and to resolve problems when mixing resource manager-provided allocations
and hostfiles. This has been an on-going discussion for some time, most
recently resulting a couple of months ago in a specification for hostfile
syntax and behavior.

Tim Prins had volunteered to modify the hostfile system to support the
revised behavior. I'm hoping he will still find time to do so once he
returns from his impending vacation. The modified hostfile component will be
moved to the RAS framework as part of this work (and then the RDS framework
will be removed).

For anyone interested, you will find a complete description of the
use-cases, desired behavior, and planned modifications in Ticket #1018 on
our tracking system:

https://svn.open-mpi.org/trac/ompi/ticket/1018

Please feel free to comment there regarding any concerns or suggestions you
might have.

Thanks
Ralph
