## Workshop: Purpose and Motivation

- Bring together researchers and engineers to identify issues and requirements for grid reliability. Of special interest:
- The scale of grid computing systems is expected to grow dramatically as grid technology transitions to industrial use.
- Operational grid systems are likely to be subjected to volatile and uncertain conditions that endanger or severely degrade effectiveness.
-  *Role/relationship of emerging WS & OGF specifications in providing reliability and robustness needed for industrial/scientific use of grids?*
- Identify approaches/methods to ensure grid reliability and robustness
- Specific methods such as Grid FTP, grid monitoring services, grid replication services, check-pointing and recovery services, mechanisms for maintaining consistent system and component states through time.
- Approaches to analysis and management of grid operation as a system; evaluate/understand system state to ensure reliable operation and service provisioning.
-  *Relationship of A&B to, and interactions with, OGF specifications being developed for management of grid infrastructure and services.*

## Grid Reliability and Robustness RG

_***Purpose:***_*** ***Make recommendations and explore methods for improving reliability and robustness of standards-based grid systems.
_***Main Product:***_*** ***Produce OGF Informational Document that
- Summarizes the state of work on Grid and WS system reliability based on input from grid system practitioners/researchers
- Identifies issues that must be addressed/solved to ensure reliability and robustness in grid systems that are based on WS and OGF standards
- Identifies requirements for establishing and maintaining high levels of reliability in future large-scale Grids.
- *Document will serve as resource on reliability issues for GGF working groups developing specifications and for grid developers.*
- First draft in progress; completion at end of 2007 *Contributions, review needed!*
_***Additional Products:***_*** ***
- Facilitate collaborations between researchers on grid reliability
- Preliminary requirements for reliability measurement methods and tools
***Web pages and reflector***
