	P2956R2	Add saturating library support to std::simd	D. Towner, R. Arutyunyan	LWG
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LWG Revisions R3 Tracking issue View on GitHub Abstract The Working Draft of C++26 includes data parallel types. It mostly provides operators which work on or with `std::simd` types, but it also includes overloads of useful functions from other parts of C++ (e.g., sin, cos, abs). In [P0543R3] a proposal was made to provide saturating operation support for some basic arithmetic operations and casts. In particular, `saturating_add`, `saturating_sub`, `sa
	P3787R2	Adjoints to "Enabling list-initialization for algorithms": uninitialized_fill	G. D'Angelo, R. Arutyunyan	LEWG LWG
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Giuseppe D'Angelo, Ruslan Arutyunyan Target Audience LEWG LWG Revisions R1 Tracking issue View on GitHub Disposition Date 2026-03Adopted Abstract In the Tokyo 2024 meeting [P2248R8] (Enabling list-initialization for algorithms) was adopted.
	P3804R2	Iterating on parallel_scheduler	L. Teodorescu, R. Arutyunyan	LWG
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Lucian Radu Teodorescu, Ruslan Arutyunyan Target Audience LWG Tracking issue View on GitHub Disposition Date 2026-03Adopted Abstract `parallel_scheduler` [[P2079R10](https://wg21.link/p2079r10)] was a long time in the making and was it adopted in Sofia 2025; still more design concerns were raised after that. This paper proposes to iterate on some of these aspects, aiming to achieve the best possible outcome from `parallel_scheduler`.
	P3983R1	simd object representation	D. Towner, R. Arutyunyan	LEWG LWG SG1
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG LWG SG1 Revisions R2 R0 Tracking issue View on GitHub Abstract The Working Draft makes `simd` types trivially copyable types, which allows `std::bit_cast` operations. However, the object representation is unspecified, making the results implementation-defined.
	P4154R0	Renaming various execution things	T. Song, R. Arutyunyan, A. O’Dwyer	LWG
