DMLT Meeting Goals

  • Weekly meeting to keep the DM leadership team coordinated, informed, and in agreement on the vision, priorities, and challenges facing DM construction, including surfacing and resolving issues and ambiguities needing our attention. The goal of this meeting is to provide information and decisions that help each one of us better direct our own (or our team's) activities.

Discussion Items

Guidelines: Propose items in line with the meeting rationale (see above); include as much information in the agenda notes; summarize, don't go into details while on the call; maximize time available for discussion.

30 minChange Control Board report

Gregory Dubois-Felsmann, Tim Jenness

See also Change requests of interest to DM.

  • There was some discussion on the proposed HeavyFootprints change request ( DM-9962 - Getting issue details... STATUS ). There was some confusion as to whether HeavyFootprints were already in the baseline or not.
  • Unknown User (ciardi) reported that he would send round a draft of the science case for PVI archiving by the end of today. Kian-Tat Lim will provide the sizing and costing estimate.
  • Gregory Dubois-Felsmann requested clarification regarding whether we are truly promising to deliver dynamically generated products from old data releases. He is worried that there is a hidden cost to promising this that has not been included in the plan and will write up a short note explaining the issues. LSR-REQ-0049 could be read either way. This has some impact on the costing of LCR-908 requesting that we archive all old data releases on disk, since it might imply that we have to include generation of virtual products from an older release, or alternatively, it might imply that we are saving compute resources by no longer having to provide these data products from raw data.
  • Kian-Tat Lim agreed to cost the three proposed changes described above. Mario Juric agreed to provide clarifications for LCR-908 as needed.

DMLT Travel & Availability This Week

NOTE CHANGES TO TRAVEL POLICY:  1) Due to concerns regarding liability, safety and consumer protection, AURA has determined that the use of online rental services such as AirBnB, VRBO, and Homeaway are no longer permitted for official AURA business travel, therefore Erin will not book this type of lodging.  2)  Continental breakfast (danish, pastries, bagels, etc.) is considered a full meal and will reduce breakfast per diem accordingly.  

Gregory Dubois-Felsmann will be on vacation on Tuesday and Friday ( and ).
