SSS Build and Configuration Management Update 1/2004 Highlights and Future Directions

This update provides an overview of the latest improvements in the SSS Build and Configuration Management system, as well as performance enhancements and reliability insights. Key highlights include infrastructure and library updates, the addition of component monitoring, and minor bug fixes. Additionally, new restriction syntax augmentations, including the implementation of numeric and negation operators, enhance functionality. The document outlines future work plans focusing on hardware infrastructure, model refinements, and the integration of new wire protocol modules. Overall, the system has demonstrated reliable operation in production for approximately six months.

  1. Narayan Desai desai@mcs.anl.gov SSS Build & Configuration Management Update 1/2004

  2. Overview • Infrastructure Updates • Library Updates • Configuration and Management Components • Restriction Syntax Augmentations • Next

  3. Infrastructure Updates • Most updates minor bugfixes • Infrastructure has been reliable in production for ~6 months • Addition of component monitoring to service directory • Minor performance improvements

  4. Library Updates • Portability Improvements • Robust OSX support • 64-bit operation tested • Early Tru64 support • Thread-safety • SSL wire-protocol module • Implementation now well tested • Soon to be the default protocol in ssslib distribution

  5. Configuration Management Components • Node state manager • Relied upon on chiba city • Specification to be presented • Build System • Need to match the external configuration interface more closely with the underlying configuration management system • Current model artificially splits boot services from configuration services • Model needs refinement • Hardware Infrastructure • Need a clearer set of consumers of hardware and topology data • Model clearly needs refinement

  6. Restriction Syntax Augmentations • New operators implemented • Numeric operators • The much requested negation operator • Regular expression matching • Easy to implement more • Integrated into all components

  7. Next • Work on models and new implementations for hardware infrastructure and build system • Work on multiple implementations of BCM components • More wire protocol modules (if needed) • More portability fixes (if needed) • Performance tuning
