01In brief

The short answer.

Data and Compute subject groups are moderated forums where data engineers and HPC specialists discuss open questions in the data and compute field, such as public interest data infrastructure and high performance computing. Each group is listed once its moderation, terms and hosting are in place, with its scope and how to join. A group informs the platform's work and has no authority over its findings.

From enquiry to contribution.

Canvas · from enquiry to contributionDesign, not a record
Subject groups: a working group from charter to sunsetA charter sets the question and the code of conduct; members join with declared interests; a workplan produces deliverables that are reviewed and credited; the group reports and sunsets or renews. Design of the process, not a record of a run.

03Geography

People and exposure in the contiguous United States.

For subject groups, in GCRI's spatial-intelligence reading, the map opens on night lights, population density and true-colour imagery with true colour from NASA GIBS, framed on the contiguous United States; every other NASA layer, live feed and forecast waits in the layer list.

The interactive map needs JavaScript; the layer list and sources are below.

04How it works

Subject groups in Data and Compute.

  • Each entry shows its scope, host or owner, and terms.
  • Participation follows published rules, applied equally.
  • Taking part gives no authority or influence over findings.
05Group themes

Subjects where data and compute specialists most need a shared forum.

Data and compute groups bring research infrastructure operators, data stewards and energy planners together, because access, stewardship and sustainability are decided in different places but constrain each other.

  • Research infrastructure.
  • Compute sustainability.
  • Data stewardship.

07Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Community of practiceA group of people who share a concern or a craft and learn to do it better by interacting regularly; the term comes from Lave and Wenger's work on situated learning.
Chatham House RuleA rule under which participants may use information received but may not reveal the identity or affiliation of speakers.
High-performance computingAggregated computing power, typically clusters with fast interconnects, used for large simulations.
Official statisticsStatistics produced by national statistical systems under professional and legal standards.
