General Topics

• The name

  • Carl: Grateful to resolve this (paperwork for CI, funding proposals, common "branding")
  • Poll conducted over slack, closed when this meeting started
    • (pre-filled results, double-check when meeting starts)
    • Strongly Kokkos Comm: 3
    • Weakly Kokkos Comm: 5
    • Neutral: 0
    • Weakly Kokkos MPI: 6
    • Strongly Kokkos MPI: 1
  • (tentative) Results solidly in favor of Kokkos Comm, so let's keep that name

• Transports/CommunicationSpace PR: #109

  • Definitely want to support NCCL
  • Do we have preferred space + fallback if primary does not (yet) support
  • Do we always use preferred or is it a runtime decision
    • Maybe this hybrid is actually different CommunicationSpace?

• Starting discussions about semantics for calling Kokkos Comm inside a parallel region
