Extension: A New Service? • Experiment coordination meeting – Alberto Aimar and Denise – Shifter use cases: • ATLAS – 2 persistent chatrooms in Oslo, based on jabberd – 1 for virtual control room and 1 for distributed analysis – about 100 users, using external accounts (jabber, gmail and others) • CMS – one shifter is always connected on AIM with a predefined account – a list of experts is also on AIM and can be contacted – also using a Computing Logbook (elog) for keeping a permanent record – Meeting with ATLAS, CMS, and Indico – Strong interest in having a supported service (inside and) outside Indico CERN - IT Department CH-1211 Genève 23 Switzerland www. cern. ch/it Chat Room Service- GLM [Aug 2010] - 5
