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
