A single source of truth for the repositories adjacent to SutroYaro. Updated 2026-05-09.

Active research front (May 2026)¶

These repos are where current work lives. If you're picking up the project, start here.

Repo	What it is	Latest activity
`SutroYaro`	This repo. Lab notebook for Phase 1+2 work, autonomous-research infrastructure, public docs site, sparse-parity scoreboard.	Active
`ByteDMD`	The primary cost metric (data-movement complexity, byte-granularity LRU stack). Yaroslav's active research front lives at `experiments/grid` — self-contained experiments.	Active
`simplified-dally-model`	Yaroslav's 2D Manhattan-grid cost model. Single-processor, explicit communication cost. Goal: minimum instruction set that captures the relevant cost dynamics. Will eventually replace 1D Dally pJ numbers in the SutroYaro eval harness.	Active (2026-05-08)
`sutro`	Main code repo. Owns `sparse_parity_benchmark.py` and the original solver implementations.	Reference
`sutro-problems`	Small reproducible problems collection. Has the matmul energy-metric work. Andy Zhang is now an owner (Telegram, 2026-05-06) and active on this.	Active
`sparse-parity-challenge`	Submission pipeline: submitters open a GitHub Issue with a `solve()` function; CI auto-evaluates under ByteDMD and posts the score.	Active

Companion baseline catalogs (shipped May 2026)¶

Reproducible-baseline implementations of the synthetic learning problems from two distinct paper lineages. Both shipped via the agent-team build pattern; see each repo's BUILD_NOTES.md for the session-level details.

Repo	Paper lineage	Stubs	Site
`hinton-problems`	Hinton 1981–2022 — representational toy tasks (4-2-4 encoder, family trees, shifter, capsules, Forward-Forward)	53 v1 + 2 add-ons	site
`schmidhuber-problems`	Schmidhuber 1989–2025 — algorithmic capability (long-time-lag indexing, key-value binding, Levin/OOPS search, controller+model+curiosity, World Models)	50 v1 + 8 v1.5	site

Together: the representational + algorithmic baseline pair. Both are pure numpy + matplotlib, laptop-runnable, with paper-comparison metrics per stub. The follow-up v2 work is to instrument these baselines with ByteDMD and compare data-movement cost across algorithm families.

Tracking issues: - hinton-problems #45 (v2 ByteDMD) and #46 (v1.5 paper-scale) - schmidhuber-problems #17 (v2 ByteDMD) and #18 (v1.5 paper-scale + original-simulator)

Adjacent / external¶

Repo	Connection
`adotzh/SutroAna` (not in cybertronai org)	Anastasia Zhiboedova's auto-research-loop framework. Presented at meeting #16 (04 May 26). Independent of SutroYaro but solving overlapping problems.

Older `cybertronai` repos (reference, not active for this work)¶

The org has a long history. These are not currently part of the energy-efficient-training thread but are useful background:

scaling-laws, autograd-hacks, autograd-lib — Yaroslav's instrumentation tools
pytorch-sso, pytorch-lamb, pytorch-fd — second-order methods, LAMB, fluctuation-dissipation
gradient-checkpointing — memory-efficient training
transformer-xl, imagenet18, Megatron-LM, bflm — training-at-scale work
ncluster, pytorch-aws, aws-network-benchmarks, autotune — AWS / training-infra tools

Reading the diagram:

Purple (left) — cost-metric repos. ByteDMD is current; simplified-dally-model is the 2D grid successor Yaroslav is iterating on.
Blue (middle) — problem repos. The submission pipeline (sparse-parity-challenge), the two companion baseline catalogs (hinton-problems, schmidhuber-problems), and sutro-problems for everything else (matmul energy-metric work, etc.). sutro holds sparse_parity_benchmark.py which feeds the challenge spec.
Green (right) — the lab. SutroYaro consumes the cost metric + the problems and produces: scoreboard, accumulated findings (DISCOVERIES.md), autonomous-research infrastructure, public docs site.
Gray (dashed) — adjacent. adotzh/SutroAna is solving overlapping problems independently (presented at meeting #16, 04 May 26).

Updating this doc¶

Maintained by hand for now. Bump alongside the active-threads catch-up when:

A new repo is added to the cybertronai org
Yaroslav signals "this older repo is now active again"
The conceptual map changes (e.g., simplified-dally-model becomes the primary metric and 1D ByteDMD goes to reference)

The gh repo list cybertronai --limit 50 command is the authoritative source of what exists; this doc is the curated narrative.
