Agenda

• Announcements
• Library Initialization
• Component architecture

Project name: UCC

• No major conflicts
• Conflicts with upstream have not been discovered, yet
• There are some minor conflicts with the acronym but does not seem to be a major concern

CLA

• No conclusion yet. But, moving towards the direction where if you have signed a CLA for UCX and also a UCF member, you don’t have to sign a new CLA.

The patch to conditionally build an experimental UCG submodule

• Alex has a wiki page providing an overview of the build process and usage

UCC F2F

• With the situation around COVID-19, it seems prudent to have a virtual f2f rather than a physical meeting. The virtual f2f to span over a week (Mon-Fri) and four hours of meeting time each day.
• This is not necessarily the same as f2f from a productivity perspective, but we can revisit the idea of physical f2f as things calm down.
• Send out some options for April (mid to last week) to choose the most convenient time frame for the majority (AI: Manju)
• Logistics - Inclination to use BlueJeans
• Time slot: TBD based on the potential participants.
• Send an invite to potential participants who are not necessarily regular attendees.

WG meeting to move to weekly cadence.

• Send out a poll for choosing appropriate time (AI: Manju)

Library initialization

• Discussion from the previously distributed slides
• Don’t support experimental API and instead use the library versioning approach (borrow the idea from RDMA Core and UCX is moving towards that direction)
• Thread models - Use two thread models (UCC_THREAD_MULTIPLE or UCC_THREAD_SINGLE) for now.
• Discussion about library usage models (to be continued in the next meeting)

Next Meeting:

March 18 or 19 to be based on the poll

Potential agenda for the next meeting

1. Library initialization
2. Resource abstraction
3. Component architecture
4. Multi-faceted API or single API?
