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. 



Status of LDM-503-n milestones
EAC & risk status updateJohn Swinbank
  • EAC update slides should be submitted to Victor by tomorrow.
  • Risk update due 15 April.
    • Still waiting for template from Kevin Long which will be provided here.
  • May 22–24, UW (Seattle).
  • You should now have submitted your travel requests.
    • Hotels are expensive; book soon. Try the Residence Inn for govt rate.
  • Please add suggestions to the fine agenda.
  • John Swinbank: Discuss the possibility of a DMLT F2F block hotel booking with Erin Carlson.  
Summer 2018 reviewsJohn Swinbank
  • Outstanding action item for all DMLT members with deadline of 19 March to review the review documentation list.
    • Can we now assume that everybody is now happy with what they have (been) signed up to deliver?
  • Answer is: no, we should try this again for next week.
Community access to lsst-dev01John Swinbank
  • (And, one assumes, to other LDF systems)
  • See this CLO post.
  • I assert that this is addressed by the material in DMTN-020:
    • “DM and LSST collaborate with many outside individuals. We also use many tools such as Jira, Slack and Confluence which are licensed for a certain number of users. To foster collaboration it is useful that some close collaborators who are not part of the project have accounts on such systems. Requests for such accounts should be made via Jira tickets in the “IHS” project, with explicit review requested from the DM Project Manager and Deputy Project Manager. Collaborators granted such accounts should make use of them: if they are not actively used for six months the accounts shall be revoked.”
  • That does not mention LDF services, though: any objections to applying the same policy there?
  • Broadly agreed with the above statement, but with the caveats that:
    • This should be used for benefits to the project, not to the end user
    • When the Science Platform becomes available, we'll encourage folks to use that instead.
  • John Swinbank: Follow up to CLO in re of Science Collaboration access to lsst-dev.
