Notes:SG14 October Monthly Meeting Summary
Overview

The meeting reviewed SG14 priorities ahead of the Brazil meeting and
identified areas for further proposal development.
Proposal Priorities

   - Finance SIG chair *Brian* supports reviewing proposals on
   kernel-bypass I/O; *Jens* emphasized portability and alignment with the
   standard’s senders/receivers framework. Proposals need concrete papers
   before detailed committee action.
   - The games omnibus paper remains the main discussion framework, but its
   author, *Patrice*, was absent. The group lacks an equivalent paper for
   embedded; ownership of remaining freestanding work is unclear.

Open Questions

   - Can contributors develop actionable finance and embedded papers to
   guide subgroup discussions?
   - *Lucas* described reflection-based expression work aimed at automatic
   differentiation. The topic was redirected to SG19; current standardized
   reflection handles declarations, not arbitrary expressions. Can the
   proposal’s goals be achieved with the reflection and code-generation
   facilities under development?

Action Items

   - Review Patrice Roy's games omnibus paper, identify sections to augment
   or support, and provide feedback; contact Patrice as needed.
   - Review the remaining freestanding and embedded work to determine what
   items are still outstanding and whether the effort can be picked up.
   - Join the SG19 reflector/forum and send a message to start discussion
   of the reflection-and-expressions proposal, including its intended
   capabilities and compile-time complexity trade-offs.
   - Prepare and share more concrete details and the proposal paper for the
   reflection-and-expressions work, targeting the Brazil meeting or the next
   relevant meeting.
   - Provide the SG19/forum signup information after the meeting. All
   forums can be signed here: https://isocpp.org/std/forums

Outline Meeting Planning

   - The C++26 DIS ballot was underway, with the result expected soon; the
   next in-person meeting was planned for Brazil in November.
   - C++29 work was expected to continue after the Brazil meeting.

Finance and I/O

   - Finance reported no current subgroup updates.
   - Participants discussed interest in kernel-bypass I/O proposals,
   including io_uring and TCP/IP direct or EPOLL; *Brian* welcomed papers
   in this area.
   - *Jens* noted the need to address portability, implementation
   requirements, and how proposals relate to senders/receivers and possible
   coroutine-based networking.

Games and Embedded

   - The group’s games omnibus paper collects requests from the games
   community and has been reviewed over multiple meetings.
   - Participants suggested similar guiding papers for finance and
   embedded. The group had no current embedded paper, and ownership of
   remaining freestanding topics was uncertain.

Reflection and Automatic Differentiation

   - *Lucas* outlined work using reflection and expressions for automatic
   differentiation and compile-time capabilities, with a possible presentation
   in Brazil.
   - The topic was redirected to SG19. Current standardized reflection
   cannot inspect arbitrary expressions; code generation remains under
   discussion.
   - The next SG14 and SG19 meetings were announced for December 9 and 10,
   respectively.
