Andrew
The meeting focused on the development of C++29 features, particularly the
need for deterministic parallel reduction algorithms for finance and
safety-critical applications. Andrew presented a new algorithm that
outperforms existing methods by 20%, achieving log(n) error accuracy. The
group discussed the potential inclusion of this algorithm as a new
standard, considering its benefits for reproducibility and performance.
Additionally, the need for free-standing support in GCC's meta header was
highlighted, with plans to file an issue for editorial correction. The
meeting also touched on the importance of embedding profiles and the
potential for new smart pointer types for embedded systems.Action Items
- MW Post the compiled C++29 directions / immediate-feature request
(including Patrice's game proposals) provide DG input on short‑term C++29
priorities).
- AD Email the canonical parallel reduction paper and slides to the
SG‑14 reflector (and to SG members) so the group can review before the
London/Croydon mailing deadline.
- documenting that the 'meta' header/reflection support must be
specified for freestanding implementations and coordinate next steps; work
with Paul to draft and submit the issue.
- When Paul/Brian submit the free‑standing meta/reflection issue, copy
Michael Wong (and Ben if reachable) on the email so SG‑14 chairs can help
forward it to the right committee/working group.
- Write and submit a formal paper describing the 'unique/shared
reference' (observable pointer) design, including an FAQ that answers how
it differs from garbage collection and hazard pointers.
- Include in the paper explicit FAQ items that explain why the proposal
is not garbage collection and how it differs from hazard pointers
(addressing the three key reviewer questions raised in the meeting).
Outline
Discussion on C++29 Features and Proposals
- Michael Wong asks the group to suggest immediate directions for C++29,
emphasizing the need for feedback to the directions group.
- He intends to highlight the gathered direction for HFT, networking
since SG14 inception in 2015 and recommend that networking be added to
C++29 immediate direction paper, in addition to profiles and pattern
matching.
- Delano expresses interest in a specific paper by Patrice Roy on games,
and Michael Wong confirms the paper's relevance.
- Michael Wong discusses the importance of updating the list of
proposals for C++29, mentioning specific proposals like memory management,
networking/tasks, and intrusive pointers.
- The group discusses the need for a profile for embedded systems, with
Scott Dixon suggesting that C++ needs an embedded profile.
Proposal for Shared Reference Smart Pointer
- Scott Dixon presents a new smart pointer type called shared reference,
designed for embedded systems.
- The shared reference allows for explicit memory reclamation phases,
addressing issues with shared pointers in embedded systems.
- The proposal includes unique reference and shared reference types,
with unique reference acting like a unique pointer.
- The group discusses the potential benefits and challenges of the
shared reference, including its compatibility with existing systems and its
impact on memory management.
Canonical Parallel Reduction Proposal
- Andrew presents a proposal for canonical parallel reduction, aimed at
providing deterministic and reproducible summation algorithms.
- The proposal uses a binary tree structure to ensure reproducibility
and accuracy, with a focus on finance and safety-critical applications.
- Andrew demonstrates the performance benefits of the proposed
algorithm, showing it to be faster and more accurate than existing methods.
- The group discusses the potential implementation of the algorithm as a
new standard, with considerations for parallelizing range algorithms and
maintaining compatibility with existing systems.
Discussion on Free Standing Meta in GCC
- Paul raises a concern about the lack of free-standing support for meta
in GCC 16, which affects the implementation of free-standing reflection.
- Michael Wong suggests raising this as an SG 14 concern, emphasizing
the importance of free-standing support for low-latency embedded systems.
- The group discusses the need for editorial fixes to ensure that meta
is marked as free-standing in the draft standard.
- Paul and Brian agree to file an issue on the C++ standard GitHub
repository to address this concern.

>>>>> Discussion on Embedded:

>>>>> The next meeting would then be Embedded and I would be interested in
