WLCG GDB Action List

This page lists actions currently monitored by GDB and topics that will require actions in the future. Note that most actions related to operations are followed by the Operations Coordination.

General Actions

Machine/job features

  • Increase the adoption: identify sites ready to install the framwork developed, see December GDB
    • Contact Stefan Roiser




  • LHCONE: discuss a process for handling requests of new experiments who want to join LHCOPN


  • Help establishing concrete links for collaboration (memory limitation, SAM, GGUS...) after June GDB

Other Items to Follow-up


  • Follow-up TEG recommendations for WN AAI and proposed focused WGs
    • Improved traceability: configuration recommendations for sites to meet the WLCG traceability requirements, take into account specific needs for virtualized WNs (including those running in external clouds)
    • Possibility to reduce proxy lifetime to 24h: preliminary analysis with experiments, milestone proposal (compatible with LS1?), implementation
    • Challenges and issues with respect to security in the usage of external/public clouds
  • Give feedback on documents about Security for Collaborating Infrastructures. See July GDB
  • Federated Identity Pilot: use for access to grid services (WLCG Pilot)


Actions on Hold

June 2015

  • GOCDB extension properties: VOs should report to WLCG IS TF envisioned use cases to define a consistent usage strategy
  • Establish a list of Class 2 services (VOBOX terminology) run by every VO (VOBOX and other services)
    • Initial list to be started by J. Templon with ATLAS information (June 2015)

January 2015

  • Raise awareness on bitcoin mining activities: lower activity in the last month
    • Discuss with EGI (and OSG?) common communication actions and documentation for sites

    • Start tests with volunteering sites (limited number) and hardcoded number of cores (suggestion 4)
    • Publication of multi-core capabilities in IS: final decision on open issues in last proposal made during the summer
      • Use a pragmatic approach: not looking for the perfect specification but the one allowing to handle the main use cases with the minimal amount of development (both for MW and experiment frameworks)
