SSS Deployment using OSCAR

OSCAR (Open Source Cluster Application Resources) is a framework designed to streamline the installation, configuration, and operation of cluster management solutions. This document discusses the deployment of the SSS (Scalable Storage System) suite using OSCAR, highlighting features like a user-friendly wizard for setting up the entire cluster, package-based frameworks, and the types of software components included. Emphasizing support for various Linux distributions, it also provides insights into ongoing and future updates that enhance installation, testing, and overall usability of the system.

  1. SSS Deployment using OSCAR John Mugler, Thomas Naughton & Stephen Scott May 2005, Argonne, IL SSS Face-to-face meeting

  2. OSCAR: Cluster Toolkit • Framework for cluster management • simplifies installation, configuration and operation • reduces time/learning curve for cluster build • requires: pre-installed headnode w. supported Linux distribution • thereafter: wizard guides user thru setup/install of entire cluster • Package-based framework • Content: Software + Configuration, Tests, Docs • Types: • Core: SIS, C3, Switcher, ODA, OPD, (Support Libs) • Non-core: selected & third-party • Access: repositories accessible via OPD/OPDer

  3. OSCAR Wizard * OSCAR-3.0 release

  4. Using OSCAR for SSS Problem: Helping users obtain and install SSS software. Solution: Leverage OSCAR framework to package and distribute the SSS suite, sss-oscar. sss-oscar A release of OSCAR containing all SSS software in single downloadable bundle.

  5. OSCAR-ized SSS Components • Bamboo – Queue/Job Manager • BLCR – Berkeley Checkpoint/Restart • Gold – Accounting & Allocation Management System • LAM/MPI (w/ BLCR) – Checkpoint/Restart enabled MPI • MAUI-SSS – Job Scheduler • SSSLib – SSS Communication library • Includes: SD, EM, PM, BCM, NSM, NWI • Warehouse – Distributed System Monitor • MPD2 – MPI Process Manager * As of May 2005

  6. Current Status • Released v1.0 at SC’04 • Based on oscar-3.0 (using Red Hat 9/x86) • All SSS components represented • Testing for v1.1 release • Small update release • Still oscar-3.0 based • Synchronize with OSCAR release schedule • oscar-4.1 released • Shift to oscar-4.1 in sss-oscar-1.2 release (2Q2005)

  7. OSCAR v4.1 Highlights • SSS’s APItest tool integrated into v4.1 release • Improved use of DepMan/PackMan abs. layer • Distributions supported in v4.1 • x86: RH 9, FC2, MDK 10.0 • x86 & ia64: RH EL 3 • Initial work started for Debian  • Not in v4.1 release but working with 4.x devel tree

  8. TODO: SSS • Short term • Complete testing for v1.1beta & release • Update SSS documentation • Medium term • Migrate to new FRE testbedand repository (pending approval) • New/more Linux distribution/architecture/kernel support • Longer term • Extend SSS component tests 1) Installation, 2) Validation, 3) Durability/Stress, 4) Performance • Track oscar-4.x releases for v5.0 compatibility • Distribute as OSCAR “Package Set” • Pending feature support in OSCAR • OPKG ordering within a phase • Pending feature support in OSCAR

  9. SSS-OSCAR Release Schedule Add features to Tracker @ http://sf.net/projects/sss-oscar/

  10. Roadmap • 1.2 (frz: jun, rel: jul) • Fedor Core 2 / Pkg rebuild • BLCR upgrade to linux-2.6 • Improved install/validation tests • oscar-4.1 opkg modifications (updates) • Updates to HOWTO as needed • Simplify XML meta file • Close (most) open tracker issues • 2.0 (frz: aug, rel: sep) • LRS change over • Fedora Core 4 / Pkg rebuild • Improved install/validation tests • Add performance/stress tests? • oscar-4.x opkg modifications (updates) • Updates to HOWTO as needed • Meta-scheduler (Silver)? • 2.0.1 (frz: oct, rel: nov) [SC’05] • Any bugfixes/minor updates • 2.02 • SSS oscar-pkg set

  11. Goals for sss-oscar-2.0 • Release v2.0 at SC’05 • Compatible with oscar-5.0 • Support current Linux distribution(s) • Improve interoperability with standard OSCAR • Users obtain via “SSS OSCAR Pkg Repository” • Likely leverage “Package Sets” for logical grouping • Clarify SSS package dependencies • What about outside of SSS-OSCAR? • Improved testing • Supply thorough installation/validation/performance tests • Documentation • Specifications for component interfaces (schemas), etc.

  12. Comments/Discussion • Provide a lower cost of entry • Doc to help knit system together • Clarify dependencies/interactions • Intra-component and inter-component • Feedback to help Ron O. for testing/validation • Tests to verify against component specs. • Ex. The PM specs state X capability & it work in this build • Effectively conformance tests to “optional” SSS specs. • What do we need to help coming releases? • Louder drum for Thomas? • Dedicated integration periods (face-to-face and/or virtual)?

  13. Resources • ORNL test clusters • Systems: sss-xtorc, test1, test2 • Access via ORNL SSH Login Server • Must do reservations/coordinate use (Note, no remote power mgmt) • Investigating ORNL “FRE” (enclaves) • Add “testX” system to alleviate ORNL SSH Login Server • SSS-OSCAR Project page • Hosted at http://sourceforge.net/projects/sss-oscar/ • OSCAR Homepage • http://www.OpenClusterGroup.org/OSCAR/ • Includes “HOWTO: Create an OSCAR Package” document
