llama.cpp Multi-GPU Parallelism (verified against docs/multi-gpu.md on master)

Split modes (--split-mode / -sm)

• layer (default): Pipeline parallelism. Each GPU holds a contiguous slice of layers. Token flows through GPUs sequentially. Minimizes inter-GPU data movement; tolerates slow interconnects (PCIe fine). Best for prefill and fitting large models. Weakness: needs many tokens to keep pipeline full, poor low-batch latency.
• tensor (experimental): True tensor parallelism. Splits each layer's weights AND KV cache across all GPUs via a 'meta device', doing cross-GPU all-reduce per layer (NCCL). Minimizes latency, parallelizes any workload size. Heavily bottlenecked by interconnect speed (wants NVLink + NCCL). Best for fast token generation.
• row (deprecated): Row-split dense weights only. Predecessor to tensor; comparatively poor performance.
• none: Single GPU, selected via --main-gpu.

Key constraints on tensor mode

• Requires flash attention ON (-fa on)
• KV cache must be non-quantized: f32/f16/bf16 only
• NOT implemented for: MoE/hybrid, Mamba/SSM, and several other architectures (hard-fails with SPLIT_MODE_TENSOR not implemented)
• --fit is disabled; must size --ctx-size / --parallel manually

Separate axis (NOT model parallelism)

• --parallel / -np: Number of concurrent server slots (each with own KV cache). Serving-level concurrency/batch parallelism. On single GPU this is the main throughput knob.
• CPU+GPU offload (--n-gpu-layers, --n-cpu-moe): Hybrid inference when model exceeds VRAM. Device-distribution strategy, not 'parallelism' in the strict sense.

What does NOT exist in llama.cpp

• No first-class context/sequence parallelism mode (unlike vLLM/TensorRT-LLM). If you see that term applied to llama.cpp, it's loose third-party language.

User hardware context

• Single RTX 4070 Max-Q (~12 GB VRAM). Multi-GPU split modes (layer/tensor) do not apply. Relevant knobs: --parallel for concurrency, CPU+GPU offloading for models >12 GB.

Blankpad niri layout: externals left of eDP-1

Final committed layout (83c9c92, 2026-09-16):

• DP-2: x=0, portrait 1200x1920, transform 90 CCW, scale 1
• HDMI-A-1: x=1200, portrait 1200x1920, transform 270 CCW, scale 1
• eDP-1: x=2400, 1536x864, scale 1.25 (restated per block-reset trap)

X-offset chain: 0 → 1200 (DP-2 portrait width) → 2400 (HDMI-A-1 portrait width) → eDP-1.

Config path: ~/.omp/dotfiles/zz-blankpad/niri/.config/niri/cfg/display.kdl Repo: dank/command-center (main), local Gitea at 192.168.0.143:3000.

The skill niri-output-rotation-pinning was followed correctly end-to-end. No new pitfalls discovered beyond what the skill already documents.

Niri Display Rotation (Portrait 180° Flip)

Hardware

• eDP-1: Lenovo laptop panel, 1920x1080, scale 1.25, normal transform
• DP-2: PNP(XYM) PM1601, 1920x1200, scale 1, portrait (was 270° CCW → now 90° CCW)
• HDMI-A-1: PNP(XYM) PM1601 demoset-1, 1920x1200, scale 1, portrait (was 90° CCW → now 270° CCW)

Key Technical Facts

• Niri config split into ~/.config/niri/cfg/*.kdl (Noctalia-style includes)
• Display config: ~/.config/niri/cfg/display.kdl — per-output transform field in KDL
• niri msg outputs — shows current transform, logical size, scale, position
• niri validate -c <path> — dry-run validation before applying
• niri msg action load-config-file — hot-reload config at runtime (no restart needed)
• After rotation in portrait, logical size swaps (1920x1200 → 1200x1920) but logical position X may shift; verify with niri msg outputs after reload

Critical Pitfall: Portrait 180° Rotation

• In portrait, "flip 180°" = swap 90° ↔ 270° transform values
• Setting transform "180" on a portrait monitor kicks it to landscape-upside-down
• Niri transform values are absolute: normal, 90° counter-clockwise, 180°, 270° counter-clockwise — no modular arithmetic

Workflow (Reusable)

1. niri msg outputs — capture current state
2. Read ~/.config/niri/cfg/display.kdl
3. Edit transform values (90↔270 swap for 180° portrait flip)
4. niri validate -c ~/.config/niri/config.kdl — confirm valid
5. niri msg action load-config-file — apply
6. niri msg outputs | grep -E '^Output|Transform|Logical|Scale' — verify
7. git add && git commit && git push in dotfiles repo (/home/blank/.omp)

updated_at: 1789368866 Task: user requested changing Noctalia theme yellow to red and terminal text color to same red; rollout ended before applying edits after an ask about crispness scope was interrupted.

Noctalia facts: Niri-based DE at /usr/bin/noctalia. Main config ~/.config/noctalia/config.toml. Niri config includes noctalia.kdl for display settings. IPC uses direct noctalia msg <command> instead of qs wrapper; key commands panel-toggle, session, lock, launcher. App templates in /usr/share/noctalia/assets/templates/ for gtk, ghostty, alacritty, hyprland, sway, wezterm, helix, btop, starship, qt, kde, cava, scroll, mango, umbriel, foot, emacs, kitty. Palette is generated from an image with noctalia theme [image]. Migration notes: Ghostty should use theme = noctalia; Alacritty can import noctalia.toml theme; GTK 3/4 accent palette default mentioned as #b267e4 purple; Niri keybinds should map to noctalia msg commands.

Theme-edit workflow: for changing a Noctalia accent such as yellow to red, prefer locating and editing the generated Noctalia palette/theme source before hardcoding per-app colors. If Ghostty is set to theme = noctalia, direct terminal color overrides may be less durable than updating the theme itself. Terminal text color should match the chosen red in both the Noctalia palette and any terminal-specific override if used.

Config discovery in this environment: expected ~/.config/noctalia/config.toml and ~/.config/ghostty/config were not successfully read due shaken/pruned tool output. Candidate locations included ~/.config/noctalia, ~/.config/ghostty, and /home/blank/.omp/dotfiles/noctalia/.local/share/noctalia under cwd /home/blank/.omp. Use ls/glob/read on specific files rather than assuming a single canonical path.

Niri crispness facts: in niri 26.04, true compositor AA is limited to corner rounding via niri_rounding_alpha() smoothstep and unused gradient/hue interpolation. Corner AA is driven by window-rule geometry-corner-radius with clip-to-geometry; setting radius 0 short-circuits the shader. Background blur/noise are not AA but cause softness: background-effect { blur true } plus top-level blur { passes 2, offset 3.0, noise 0.03 } creates frosted glass and film grain. Shadows were already off. Wayland clients rasterize text; niri does not alter glyph AA. Ghostty font AA is controlled by freetype-load-flags, while other apps use fontconfig or app-specific settings. No nearest-neighbor resample knob was found in this build.

Decision guidance: when asked to turn off all compositor AA for a crisp look, explain there is no single switch; offer scoped options: hard corners only; hard corners plus disable backdrop blur/noise; full maximum crispness with terminal opacity 1.0/blur 0 and global fontconfig antialias false; or terminal-only crispness. Warn that removing blur/noise changes Noctalia's glass aesthetic.

updated_at: 1789267061 Noctalia DE (Niri-based): bin /usr/bin/noctalia; configs ~/.config/noctalia/config.toml + noctalia.kdl. IPC via noctalia msg (replaces qs -c noctalia-shell ipc call). Key cmds: panel-toggle, session, lock, launcher. App templates /usr/share/noctalia/assets/templates/. Palette gen noctalia theme [image]. GTK accent #b267e4. Text AA: Ghostty font-subpixel-render=off, Alacritty font.antialias=false. FLM NPU (Dankclaw): gemma4-it:e4b, port 7771. Supports PNG/JPEG; rejects WebP (convert first). Requires thinkingLevelMap in models.json. FIFO queue, ~7-11s model switch. Pitfall: missing .xclbin symlinks under ~/.config/flm/xclbins/ cause failures. Frank desktop: cursor 36 (gsettings org.gnome.desktop.interface cursor-size, GTK settings.ini, XCURSOR_SIZE=36), theme capitaine-cursors. Authenik 2026.8 outpost caches claims per session (1-24h TTL), causes silent 403s post-group-add despite correct membership. Halogen runtime (frank-large): baked-in chat template, no file swap. Accepts chat_template_kwargs (enable_thinking, preserve_thinking, reasoning_effort). frank-small uses checkpoint's fixed Qwen3.6 template; deploy-plan.py mapping is vestigial.

Cloned serverAppConfig to ~/Projects/serverAppConfig (HEAD 701ab14, main tracks origin/main, HTTP transport with embedded dank token, no SSH keys). Local dir is singular (serverAppConfig), remote repo is plural (serverAppConfigs). Structure (308 files, 4.2 MB):

• dankclaw/: Dankclaw stack defs.
• dankserver/: Inference backend config.
• frankbook-pro/: 7 quadlet units (sonarr, radarr, lidarr, readarr, prowlarr, qbittorrent, gluetun).
• shared/: Homepage (html/css/js + services.json), alloy, loki, prometheus, searxng.
• tests/: 47 files, E2E suite.
• serverAppConfigs-docs/: 115 files, Architecture KB (deployment flow, network/storage/ testing policy, container netns, Dankclaw service pages).
• old/, report/, scripts/, .githooks/, AGENTS.md: legacy, reports, tooling, hooks. Recent commits: observability quadlet cutover (loki/alloy/comfyui images, grafana OAuth secret per-service env seeding, docs commit recording exposure posture + unconfigured state). Pitfall: Local dir name mismatch vs remote repo name (trivial, pull/push unaffected).
