Action Items


SessionAction Items
User workspace requirements
  • Need a new term to refer to user-created tables that are do not bring the full spectrum of "Level 3" requirements; i.e., user uploads a random catalog, what do we call that?
    • Context: Gregory suggested that a user could make a "level 3" data product on their home computer, but Frossie suggests this shouldn't be conflated with products stored on the DAC
  • Need to clearly specify that we support a MyDB-type storage of arbitrary data, does not have to be related-in-scientific-meaning to the LSST data products
  • Determine how tables will be uploaded to MyDB, either by Portal or Notebook or external clients.
  • There was a discussion of "direct access to consolidated database", beyond capabilities of IVOA protocols. Need to follow up on whether this is  mediated by DAX services or if some form of more direct connection to consolidated DB is acceptable.
  • Science platform requirements say MyDB reqs are "still in development"
  • Scope effort for providing user-facing crossmatches/comparisons with other surveys, beyond those that are already in-use for Pipelines validation.
  • What are the sizes of user-generated data in existing archives? Our 10% for users is probably too small. Leanne Guy will ask Gaia archive for user data volumes.
  • What is the story that we will tell reviewers for how external groups will leverage more compute/storage, of their own acquisition, beyond the 10%? What development requirements does such a system impose on us, and what decisions do we need to make to support this "beyond 10%" capability? Do we have appropriate requirements in the baseline, and to support evolving this N-years into operations?
  • Leanne Guy will write a tech note listing some "Level 3"/"MyDB" science use cases.



Pre-Meeting Planning

Suggested topics for discussion

TopicRequested byTime required (estimate)Notes
Deployments of all three aspects within one instance
  • Identify the issues before the F2F if any
  • Resolve them and have a documented deployment procedure
  • PDAC cluster move into the k8s commons in Oct.? More details needed
Connect all three aspects
  • Search result user gets at portal is accessible through NB, and vice versa.
  • Search submitted by DAX API is accessible through portal and NB.
A+A
  • Understand and clarify the different types of tokens before F2F
  • Portal and DAX resolve the token passing issues
  • login page supplied by NCSA for portal access
  • login and get the token for DAX
  • user management (password change, etc.)
WebDAV API for workspace
  • relationship with A+A needs to be clarified
Python access to LSST data (next to database process)
  • afw.table data access through butler, enable panda compatible format (but it may be not realistic to provide it in time)
  • access to Parquet formatted data?
  • 2 use cases: after burner data process with LSST pipeline; just get the data as close as to community standard as possible and so the community tools can be used
  • Fritz Mueller Colin Slater will give a status on this
Tour of NPCF facility

Joel Plutchak or Michelle Butler can coordinate if this is desired.

1.5 hoursIf desired, a tour of the National Petascale Computing Facility can be arranged. ~45 minute tour with 10-15 minutes travel each way.
Perspectives from elsewhere in NCSA:
  • Lessons learned from DES data access infrastructure (tools, usage, etc)
  • National Data Service (NDS) as a scientific gatewa

TRANSPORTATION

Airport

The University of Illinois Willard Airport is 5 miles south of the Home2suites in the village of Savoy. Taxi, Lyft, or Uber should be about $12 plus tip.

Mass Transit

C-U buses generally cost $1 per one-way trip. iStops are campus stops where it is unnecessary to pay a fare to ride the Gold, Illini, Silver, Teal, and Yellow routes. iStop locations are indicated on individual route maps with an iStop symbol (an orange octagon with a white "i" inside) and are identified as such on bus stop signs at the stop location.

The Brown route is closest to the Home2 Suites with a stop at Fox Drive and State Street. Disembark at Springfield and Sixth; NCSA is ½ mile northeast. Route 9B is counter-clockwise (to NCSA), route 9A is clockwise (to the hotel).

A Gold route stop is a long block north of the hotel at State and Kirby. Disembark at the Ceramics building shelter on Goodwin Avenue; NCSA is 0.3 miles north. Take Gold East to NCSA, Gold West to the hotel.

Use the C-U MTD Trip Planner to investigate times and options, but beware of options having you board/disembark at Lot E-14 or St. Mary's and Oak. To get to/from the hotel you have to traverse the narrow St. Mary's Road under an overpass with no sidewalk or shoulder and plenty of morning/evening traffic.
