1. Comp@P1 Shift Move to ACR Comp@P1 Shifts are taken solo since Aug. 1, 2010 – The shifter stays alone without anyone nearby from the late night though the early morning (night shifts fully alone!!) – Safety of the shifters become concerns, let alone boredom Computing management and the run coordination reached to an agreement to move all Comp@P1 shifts to ACR – Excellent timing since Comp@P1 shifts were shutdown through Jan. 31, 2011 – Leaves plenty of time to prepare for the shifts Had discussions with run coordinators and the ACR sysadmins to learn issues and options

2. Comp@P1 Shift Move to ACR – The Basics Shift desk: – Each of ACR shift desks currently have four 17” monitors – The run coordinators will make a decision on which desk to be used for Comp@P1 shifts in early Jan. Access to ACR: – All shifters, AMODs and Computing management personnel need to be trained to obtain access clearance to ACR – Olga tells us Level 4A training is needed We will confirm this after the shutdown and notify all personnel

3. Comp@P1 Shift Move to ACR – Shift Computer Macs are not allowed as ACR All ACR machines are rack mounted PC with SL5 Need to verify that all Comp@P1 shift apps work on SL5 Monitors will also be the standard 17” ones  Some technical issues to be resolved with the optimal T0 Conzole display

4. Comp@P1 Shift Move to ACR - Network Two possible solutions – Custom: The SL5 PCs for Comp@P1 will be directly on CERN network outside P1 firewall Unpreferred solution by the sysadmin and run coordinators – Makes the hot spare switch-over difficult Setup and access to all current and future Comp@P1 shift URLs much easier  We control the list of URLs via simple bookmarks – Standard ACR inside the P1 firewall We need to provide all URL’s down to the glory details for sysadmins to add into the proxy database First list of URLs and the name of the shift machine provided to Sergio – Ale will continue technical discussions further early Jan. to finalize this issue

5. Comp@P1 Shift Move to ACR - Schedule Once the desk is finalized and the network issue is agreed upon We will setup the SL5 machine for Comp@P1 shift in Jan. Notify all Comp@P1 shifters, AMODs and other computing personnel for training requirements Comp@P1 shifters will check out the configurations for two weeks starting on Feb. 1, 2011, in ACR Complete the migration into ACR by Feb. 14
