Updates on SciDAC SSS Infrastructure and BCM Management for Enhanced Event Coordination

This document provides an overview of the latest updates to the SciDAC (Scientific Discovery through Advanced Computing) SSS (Service-oriented Software System) infrastructure and the Build and Configuration Management (BCM) system as of October 2002. It includes key components such as service directory updates, event manager enhancements, SSSlib robustness, node state management, and the integration of various wire protocol modules. Additionally, it discusses error handling improvements, cluster hardware management, and the adoption of stable schemas for better resource tracking and reliability, aiming for optimal performance at moderate scales.

  1. Narayan Desai desai@mcs.anl.gov Argonne National Laboratory SciDAC SSS Infrastructure and BCM Update 10/2002

  2. Overview • Infrastructure • Service Directory • Event Manager • SSSlib • Bindings • Wire Protocol Modules • Build and Configuration Management • Cluster Hardware Infrastructure • Build System • Node State Manager • Abstraction

  3. Service Directory Status • Static Schemas • Complete Error Handling • Deployed • Reliable at Moderate Scale

  4. Event Manager • Usage Model • Stable Schemas • Relatively Complete Error Handling • Completely Rewritten • Received Moderate Testing • Potential Subscription Type Differentiation

  5. SSSlib • Robust • New C implementation • Bindings • C++ • Java • Python • Perl • Wire protocol modules • Basic • Challenge • http-rm (in development) • http (in development)

  6. BCM Abstraction • “2nd try” Abstraction • Components • Node Manager • Cluster Control • Didn’t Work • “3rd is the charm • Components • Cluster Hardware Infrastructure • Build System • Node State Manager • Why we think it will work

  7. Cluster Hardware Infrastructure • Handles new node integration • Abstracts cluster hardware infrastructure • Power Controllers • Serial Consoles • Bios Issues • Node Inventory • Node Identification

  8. Node State Manager • Node State Tracking • Basic state monitoring • Node Administrative State • Online/Offline • Corrective Action Facility • Pull the plug on bad nodes • Unknown criterion

  9. Build System • Disk Setup • Software Configuration • Software Deployment

  10. Example Node Introduction • New node added • CHI identifies node • CHI hands off control of node to BS • BS builds node into “proper” configuration • BS hands off control of node to NSM • NSM can set node administrative state • In case of errors, node can be rebuilt or other actions can be taken

  11. Soon • Start to standardize events • Enhance event data format? • Implement more wire protocols • Complete “hot-swap” tests for BCM components • Logic for the node state manager • Implement a modular cluster hardware infrastructure

  12. Issues • Abstraction problems • BCM model unknown • Implementation feedback • Multiple implementations help
