  1. Recent ARC developments in the EMI project AndriiSalnikov, IevgenSliusar UNG 2012, November 1

  2. Road behind ARC BalázsKónya, NorduGrid 2012, Uppsala, Sweden UAG First grid segment of NASU First grid clusters in Ukraine: KIPT, BITP, KNU UNG 2012

  3. EMI goal Before EMI 3 years After EMI ImplementedAgreements BalázsKónya, NorduGrid 2012, Uppsala, Sweden EMI common products UNG 2012 Repositories Standards,New technologies, Users and Infrastructure Requirements

  4. EMI Standards CE: EMI-ES (CREAM, A-REX, UNICORE/X) IS: GLUE2 XML and LDAP rendering II: EMI Registry (EMIR) SE: SRM v2.2 (dCache, DPM, StoRM) Accounting:APEL EMI Clients: ARC Clients EMI DataLib: GFAL2 EMI Security: VOMS, caNl UNG 2012

  5. A-REX Job management interfaces: • gridFTP (old one, globus-based, will be dropped) • xBES (OGSA WS-interface, not really used) • EMI-ES • Secure, Robust, Feature-rich CE • Runs on any UNIX/Linux platforms • No impact on other OS components • Support various batch systems • Easily extendable by plugins UNG 2012

  6. ARIS FloridoPaganelli, NorduGrid 2012, Uppsala, Sweden • LDAP NorduGrid • LDAP Glue1.3 • GLUE2 UNG 2012

  7. ARC service discovery NorduGrid LDAP Only Performance Issues FloridoPaganelli, NorduGrid 2012, Uppsala, Sweden UNG 2012

  8. Other components SE:ARC withdrawn own SE implementation, but works well with existing ones. Accounting to APEL: JURA (almost there). ARC Clients as EMI Clients: fully interoperable with GLUE2 and EMIR. Ongoing performance improvements and more testing. EMI DataLib: ARC DataLib is able to employ GFAL2 (code is finished), but packaging issues exist. EMI Security: caNl++ is finished, client-side integration for arcproxy tool only, same problems with packaging. UNG 2012

  9. Documentation BalázsKónya, NorduGrid 2012, Uppsala, Sweden UNG 2012

  10. UNG ARC Deployment Total sites in EGIIS: 33 • Sites in giis.grid.org.ua EGIIS: 28 • Sites in lcg.bitp.kiev.ua EGIIS: 20 Sites with GLUE2: 5 Sites with EMI-ES: 4 failed - 3 0.6.1 - 1 0.6.5 - 4 0.8.1 - 1 0.8.1.1 - 1 0.8.3 - 1 0.8.3.1 - 5 1.0.1 - 1 1.1.0 - 4 2.0.0 - 12 UNG 2012

  11. Moving the right way  • Update to EMI-2 ARC and keep it up to date • Enable GLUE2 and EMI-ES • Read the manual and find advanced configuration use-cases to efficiently utilize cluster resources • EMIR deployment in Ukraine (almost there) • Enable accounting (SGAS and APEL) • Use the latest EMI clients! UNG 2012

  12. Our contribution ARC components: • nordugridmap • PBS batch system backends • plugins for advanced use-cases • documentation • lots of bug-reports and bug-fixes Stand-alone solutions: • PHP VOMS-Admin UNG 2012
