Meeting Minutes

Highlights:

  • Recognition of Request for Comments (RFC): established to improve collaborative decision-making.
  • oneCCL API Changes Alignment with NCCL for easier integration.
  • Repository Migration Conversations: includes updates to URLs for oneAPI specifications.
  • Focused Efforts on CI Proof of Concept to enable community contributions and support members' self-hosted test hardware.

Key Discussion Points:

  1. Open Discussions:
    • John Melonakos invited open items from members before starting the primary agenda.
  2. Review of Project Feedback:
    • Highlighted the need to improve decision-making processes.
    • Emphasis on public/open discussions for collaborative and transparent decisions.
  3. CCL IPP API Changes:
    • Presenter: Gengbin Zheng
    • Objective: Align oneCCL API with NCCL APIs to improve user adoption and compatibility.
    • Key Points:
      • Motivation includes user preference for NCCL-like APIs and easier migration.
      • Proposal for C-based API by wrapping SYCL queue.
      • Explicit memory handling and scoped future considerations for out-of-order queue support.
      • Suggestions were made against stateful API design to avoid multi-threading complications.
  4. API Spec Changes by Robert Cohn:
    • Migration of oneAPI repository to UXL organization.
    • Updates to the published spec URLs and the removal of Level Zero spec from the oneAPI spec.
  5. CI Proof of Concept Progress:
    • Presenter: Aaron Dron
    • Objective: To create a conducive environment for community contributions, supporting members' self-hosted hardware, and encouraging development in UXL repositories.
    • Key Points:
      • Implementation of security best practices for testing environments.
      • Intel Developer Cloud collaboration for providing test nodes.
      • Emphasis on secure setup and guidance documentation for member-enrolled hardware systems.

Action Items:

  • Maria Garzaran: Draft and propose (the RFC utility TBD in follow-on conversations) documentation to gather feedback on oneCCL API from UXL members.
  • Aaron Dron: Continue security and implementation practices for CI proof of concept.
  • All Members: Provide feedback on CI Proof of Concept and possible documentation repositories.

Decisions/Agreements Made:

  • The RFC process is recommended when projects have substantial changes to bring the community along in the decision-making process.
  • Proceed with frameworks and NCCL API alignment for oneCCL as the preferred path, with feedback integrated through follow-on discussions.
