@Deep research Conduct a fresh technical investigation for new features or improvements that could be added to the Eaman llama.cpp patch for this system: - RX 6800 16 GiB + RX 6700 XT 12 GiB - ROCm/HIP, with Vulkan also relevant for regression compatibility - asymmetric fixed multi-GPU placement - Qwen3.6-27B with native MTP/speculative decoding - priority: greater usable context, lower VRAM use, better MTP efficiency, improved HIP performance, and long-session correctness Use the attached files as the baseline: 1. summary_eaman.md is the authoritative current project state. 2. status is the short current operational state. 3. improvemets_list.md describes features already present in the Eaman patch. 4. web_search.md is the earlier research performed on 2026-08-07. 5. AGENTS.md defines current terminology and project constraints. Do not simply repeat proposals already covered in web_search.md. Re-evaluate them only if there has been a material upstream development since 2026-08-07. Search current sources through today, prioritizing: - recent and active ggml-org/llama.cpp pull requests, issues, discussions, commits, release notes, and merged changes; - ROCm/HIP and AMD GPU repositories or documentation; - relevant work in comparable llama.cpp forks only when it contains concrete code or measurements that could realistically be ported; - MTP/speculative-decoding implementations in other inference engines when they expose a transferable memory-management or scheduling technique. Investigate these areas particularly: - MTP rollback/checkpoint state memory and precision; - speculative decoding acceptance, scheduling, batching, and multi-slot use; - context fitting and per-device memory accounting; - asymmetric multi-GPU tensor placement and pipeline scheduling; - HIP flash attention, quantized KV, VEC kernels, and allocation lifetime; - ROCm memory pools, VMM, fragmentation, and delayed OOM behavior; - GPU sampling operations such as TOP_K; - KV-cache formats or compression with realistic HIP support; - prompt/decode performance improvements applicable to RDNA2; - correctness fixes relevant to long-context MTP sessions. For every candidate, determine: - source URL and PR/issue/commit number; - current state: merged, open, draft, closed/unmerged, or abandoned; - date of the latest meaningful activity; - what changed technically; - whether current llama.cpp mainline already contains it; - whether the Eaman patch already contains or supersedes it; - likely benefit on this exact dual-RDNA2 configuration; - expected context, VRAM, prompt-speed, decode-speed, and correctness effects; - likely files/subsystems that would need modification; - implementation difficulty and validation requirements; - important risks, regressions, or hardware limitations. Be skeptical of proposed but unmerged code and unsupported performance claims. Distinguish measured facts from your own inference. Cite every time-sensitive claim directly to its source. Prefer source code, PR discussions, commits, and official documentation over summaries. Produce a Markdown report with: 1. Executive summary 2. Material changes since the 2026-08-07 search 3. Ranked candidate table 4. Detailed analysis of each promising candidate 5. Ideas rejected or already implemented, with reasons 6. Recommended top three implementation experiments 7. A concrete validation matrix for those experiments 8. A suggested update to improvemets_list.md, clearly separated from the research report Rank candidates using: - expected benefit on this hardware: 0–5 - implementation feasibility: 0–5 - evidence quality: 0–5 - regression risk: low/medium/high - overall priority: now/next/watch/reject Do not modify or claim authorship of upstream work.
