**V5 additions vs V4:**

-
|
| 261 |
-
- **QueueingController** (`scheduling/queueing_controller.py`) — ICML 2026: Replaces 5 empirical VRAM thresholds with M/G/1 queuing model. Computes λ via EMA, E[S] via Welford. Dynamic quantization feedback across 4 tiers. INVARIANT-11: never evicts below `ceil(λ × E[S] × E[blocks] × 1.15)`.
|
| 262 |
-
- **VisualKVCache** (`multimodal/visual_kv_cache.py`) — vLLM-Omni + AMD Batch-Level DP: SHA256 content-hash registry, DP mode recommendation (batch≥2 images), eliminates 58–126 all-reduce sync points per encoder pass.
|
| 263 |
-
- **SpeculativeCoordinator** (`decoding/speculative_coordinator.py`) — Cross-Attention SpecDec (May 2026): Retriever/Reranker draft → Responder/Critic verify. Overlapped drafting+verification. INV-12: target always authoritative.
|
| 264 |
-
- **PBKVPredictor** (`scheduling/pbkv_predictor.py`) — 2nd-order Markov, blend_alpha=0.6, 1.26× over KVFlow.

[0:15–0:45] DEMONSTRATE THE PROBLEM
|
| 440 |
-
Show the VRAM duplication diagram (5 agents × 12 GB = 60 GB wasted)
|
| 441 |
-
Contrast: same context cached 5 times for no reason
|
| 442 |
-
|
| 443 |
-
[0:45–1:30] THE 8 MECHANISMS (pick 3–4 to highlight)
|
| 444 |
-
- KVCOMM (simhash anchors): "We use paper #1 to match prefix offsets
|
| 445 |
-
across agents with zero RoPE drift"
|
| 446 |
-
- QueueingController (ICML 2026): "Paper #7 replaced our 5 empirical
|
| 447 |
-
thresholds with rigorous math — we know exactly when we're stable"
|
| 448 |
-
- RotateKV (INT4): "Paper #5 compresses pre-RoPE tensors 4× before
|
| 449 |
-
they hit HBM3"
|
| 450 |
-
- VisualKVCache: "Paper #8 eliminates redundant vision encoder calls
|
| 451 |
-
with SHA256 content dedup — +44.9% throughput on AMD benchmarks"
|
| 452 |
-
|
| 453 |
-
[1:30–2:00] LIVE DEMO
|
| 454 |
-
Show dashboard running (real or mock)
|
| 455 |
-
Highlight: VRAM gauge, λ/ρ stability indicator, cache hit rate
|
| 456 |
-
INV-14: "SIMULATION MODE" if showing mock data
|
| 457 |
-
|
| 458 |
-
[2:00–2:30] WHAT WE BUILT
|
| 459 |
-
"8 papers, 18 tests, V5.0 complete.
|
| 460 |
-
All code committed. Pending: real MI300X hardware validation."
|
| 461 |
-
Show: architecture diagram, module tree
|
| 462 |
-
Status table S01–S14: everything is DONE
|
| 463 |
-
|
| 464 |
-
[2:30–3:00] CALL TO ACTION
|
| 465 |
-
"AMD DevCloud has $100 in free credits. Our benchmark script costs $54
|
| 466 |
-
to run on real MI300X hardware. Every result you see here is projected
|
| 467 |
-
from papers — the real numbers will be published the moment the
|
| 468 |
-
DevCloud job completes."

**Track: AI Agents & Agentic Workflows**
|
| 476 |
|
| 477 |
-
ContextForge belongs in this track because agentic workflows are the most KV-redundant workloads in production. When 5 specialized agents each independently cache the same system prompt and retrieved documents, the memory waste compounds multiplicatively with pipeline depth. ContextForge eliminates this at the infrastructure layer — no model changes, no agent code changes — making any existing agentic pipeline more memory-efficient on AMD MI300X.
|
| 478 |
|
| 479 |
**Why AMD MI300X:** The 192 GB HBM3 makes KV cache coordination economically critical. A 40–60% VRAM reduction translates directly to either 2–3× more concurrent agents or significantly lower per-token cost.

## 🏆 Engineering Principles
|
| 304 |
|
|
|
|
|
|
|
| 305 |
| # | Principle | Description |
|
| 306 |
|---|-----------|-------------|
|
| 307 |
+
| **1** | **Silicon-Native First** | Every hot-path operation uses ROCm-native libraries (PyRSMI, HIP, Triton-ROCm). No subprocess calls in hot paths. |
|
| 308 |
+
| **2** | **8 Papers, 0 Hacks** | Every optimization backed by peer-reviewed paper. No magic constants. |
|
| 309 |
+
| **3** | **Stability Over Utilization** | QueueingController chooses VRAM safety over peak utilization. INVARIANT-11 is not a suggestion. |
|
| 310 |
+
| **4** | **Async-First I/O** | All file, network, and cross-process operations use `asyncio.run_in_executor`. |
|
| 311 |
+
| **5** | **Graceful Degradation** | Any optional dependency missing → WARNING + functional fallback. |
|
| 312 |
+
| **6** | **Zero Model Changes** | ContextForge operates entirely at the infrastructure layer. ATOM plugin is the only integration point. |
|
| 313 |
+
| **7** | **Invariant Compliance** | All 14 system invariants enforced in code. Violations raise `InvariantViolationError`. |
|
| 314 |
+
| **8** | **Honest Reporting** | Failed benchmarks (S-3, S-13) reported as-is. No cherry-picking. |

**Track: AI Agents & Agentic Workflows**
|
| 354 |
|
| 355 |
+
ContextForge belongs in this track because agentic workflows are the most KV-redundant workloads in production. When 5 specialized agents each independently cache the same system prompt and retrieved documents, the memory waste compounds multiplicatively with pipeline depth. ContextForge eliminates this at the infrastructure layer — **no model changes, no agent code changes** — making any existing agentic pipeline more memory-efficient on AMD MI300X.
|
| 356 |
|
| 357 |
**Why AMD MI300X:** The 192 GB HBM3 makes KV cache coordination economically critical. A 40–60% VRAM reduction translates directly to either 2–3× more concurrent agents or significantly lower per-token cost.
