Items Discussed

1. Progress Reports
   1. A single consolidated Progress report will be created. Everyone to send a 1-page report on their Fault Tolerant work by Monday June 4th to Rinku
2. Presentation Walk-through: Important items discussed
   1. Mapping between event categories and software component categories - It was suggested that we have the same categories across all components, since some errors/warnings, belonging to different components, will be similar in nature.
   2. Mechanism needed to assign affinity between faults thrown by different components but occuring due to a common failure.
   3. Mechanism needed to provide a single aggregate response to different reported errors for a common failure
   4. 'Event scoping and grouping' was discussed - Event grouping will be important for implementors who wish to insularly include FTB in their product. In addition, there may be faults/warnings that may not need to be propagated beyond the local system, thus establishing a need for having events local in scope. The complexity of this topic led to a joint decision that it will be discussed at a later stage in the design cycle.
   5. OpenMPI folks to provide input/ideas on any fault tolerant specific features derived on experience gained with OpenMPI
3. Face-to-face All-Hands meeting
   1. This will take place in Salt Lake city on a weekend in July
   2. CRAY representatives to be invited

Action Items

1. Component owners to work on their schemas for the components. Rinku to send out a sample.
2. Owners to send a 1-pager update on their FTB work
