It keeps the DFlash parallel diffusion backbone and adds a lightweight sequential Markov head. This models inter-token dependencies inside each block.

Commit db3eb01 added TEMP=1.0 to the env files as a sampling default; the serve scripts export it via set -a. HIP then used the path "1.0" for its cache, failed, and segfaulted with a NULL-refcount unref (offset 0x446153 in libamdhip64) during model tensor upload (ggml_backend_cuda_buffer_set_tensor). This crashed frank-default- large on every restart from Aug 13 16:22 onward; the earlier c984a3e "fix" (KV/batch changes) was unrelated. Rename the sampling variable TEMP -> TEMPERATURE in both env files and serve scripts. llama-server still receives --temp from the renamed var, so sampling defaults are unchanged. The HIP runtime no longer sees a bogus TEMP value.

Three findings emerged: + +1. **The server does not preempt.** `llama-server` defers a new task into a queue when all slots are busy. It never releases a running generation to make room. Verified empirically: two concurrent streaming jobs completed normally with dissimilar prompts, similar prompts, and near-identical prompts (high LCP reuse). `parallel=3` on Dankclaw serves up to three concurrent jobs and queues the rest. +2. **The releases were client-side aborts.** The pi coding agent aborts a stream when the user interrupts it (for example, Escape, or starting a new message in a way that cancels the previous one). The client records `stopReason: "aborted"` with `errorMessage: "Operation aborted"`, and the server logs `srv stop: cancel task, id_task = N`. The server journal shows a `slot release` line with no `cancel task` line when the generation ends normally (EOS or limit). +3. **Dankserver crashed under the parallel researcher load.** Five parallel research subagents hammered `frank-default-small` with back-to-back requests (a new task every few seconds for ~15 minutes). At 19:45:44 and again at 19:55:27 the service aborted with `CUDA error: an unsupported value or parameter was passed to the function` in `cublasSgemm_v2` at `ggml-cuda.cu:1541`. systemd restarted it, and in-flight streams died with `Connection error.` or `terminated`, then `503 Loading model` during the ~5 minute reload. This crash, not speculative decoding, killed the parallel jobs. The signature is a CUBLAS invalid-value error in a GEMM under heavy concurrent load; root cause on Dankserver (llama.cpp b10121, driver 595.84, MoE experts CPU-offloaded) was not yet determined. + +Diagnosis recipe: to tell a client abort from a server release, read the journal around the release time.

The server never preempts a running generation; when all slots are busy, new tasks defer into a queue. See the 2026-08-13 incident in [docs/deployment.md](docs/deployment.md). - Dankserver crash signature under parallel load: `CUDA error: an unsupported value or parameter was passed to the function` in `cublasSgemm_v2` at `ggml-cuda.cu:1541`, then `status=6/ABRT`, then `503 Loading model` for ~5 minutes. Happened twice on 2026-08-13 under a 5-researcher subagent storm (llama.cpp b10121, driver 595.84). Root cause not yet determined; do not confuse it with speculative decoding. +- DFlash premature EOS under parallel load: on Dankclaw, `draft-dflash` ends a generating slot ~1s after a new task lands with high prompt-cache reuse (LCP ~0.99), with `finish_reason "stop"` and no `cancel task` log. It is a DFlash shared-draft-context bug. DFlash is retired from Dankclaw; use `draft-mtp` (n_max 3) or `ngram-mod`, both parallel-safe.

When the new task's first DFlash draft pass runs after a large prompt-reuse operation, it corrupts the generating slot's draft state, and the target spuriously samples the EOG token.

Why PP is the Only Realistic Option over Ethernet + +### 3.1 Communication cost comparison + +| Scheme | Communication per tok per rank | 27B, H=4096, batch=1 | 36B, H=6144, batch=1 | +|--------|------|---|---| +| PP (Nₚₚ boundaries) | Nₚₚ × H × 2 | Nₚₚ × 8 KB | Nₚₚ × 12 KB | +| TP (L layers all-reduce) | L × H × 2 | 32 × 8 KB = 256 KB | 48 × 12 KB = 576 KB | + +PP communication per token is **L/Nₚₚ times smaller** than TP communication per token (factor of ~16× for 2 PP stages). + +### 3.2 Latency-bound nature of autoregressive generation + +During autoregressive generation, each layer computes one token at a time. In TP, every layer requires an all-reduce (2× ring latency or 1× tree latency per layer). For L=32 layers, that's 32 synchronization points per token. + +In PP, activations cross the stage boundary only once per layer (or L/Nₚₚ times). The critical path is: + +``` +Stage 0 computes → send hidden state across boundary → Stage 1 computes → ... +``` + +This is a single bottleneck per token, with latency proportional to network RTT × number of stages, not L. + +### 3.3 Bandwidth utilization + +With PP, each boundary crossing transfers `H × 2` bytes. For 8 KB at 1 GbE, the transfer completes in ~68 µs. This is negligible compared to compute time (milliseconds per layer on a GPU). The link is underutilized. + +With TP, each layer transfers `H × 2` bytes but this happens L times. For 256 KB total at 1 GbE, that's ~2 ms of pure transfer time — potentially comparable to compute time on a fast GPU. + +### 3.4 Real-world evidence + +- Petals uses PP exclusively over the public internet and achieves usable inference at 1–2 tok/s even with 100 Mbit/s links [1]. +- llama.cpp RPC splits layers across nodes in pipeline order, not tensor sharding [2]. +- exo uses TP but achieves speedup only with RDMA over Thunderbolt (~50 Gbit/s) [3]. +- Petals paper Table 3: inference performance does **not depend much on bandwidth** (1 Gbit/s vs 100 Mbit/s gives nearly identical results) but **degrades significantly with higher latency** [1]. + +**Conclusion:** For gigabit-class ethernet, PP is the only practical multi-node parallelism strategy for inference. TP can work on 10 GbE for small batches but saturates at 1 GbE with moderate batch sizes. + +--- + +## 4.

Even with TCP/IP and RPC overheads, margin is >90%. + +2. **Pipeline parallelism is the correct choice** over ethernet — PP sends 8–12 KB per boundary vs. 256–576 KB for TP, a 32× advantage for 2 PP stages. + +3. **Latency matters more than bandwidth** — the Petals paper demonstrates that dropping from 1 Gbit/s to 100 Mbit/s only reduces throughput by ~3%, while increasing RTT from 5 ms to 100 ms reduces it by ~28%. + +4. **With 8-bit quantization**, bandwidth requirements halve, providing additional safety margin. + +5. **Jumbo frames recommended** to minimize TCP overhead on larger transfers. + +6. **For batch sizes ≥ 16**, 1 GbE remains viable for PP but consider 2.5 GbE for headroom and faster model loading. + +--- + +## References + +[1] Borzunov et al., "Petals: Collaborative Inference and Fine-tuning of Large Models," ACL 2023. arXiv:2209.01188.

RPC + Speculative Decoding Compatibility + +The llama.cpp RPC backend (`--rpc `) splits **model weights and KV cache** across local and remote devices proportionally to available memory [7]. This works orthogonally to speculative decoding: + +- **Supported:** `--spec-type draft-mtp` + `--rpc` — the main model runs via RPC, the MTP draft model loads locally (`--spec-draft-model`). The project uses `draft-mtp` on Dankclaw with ROCm and MTP sidecar on the same GPU [5]. +- **Supported:** `--spec-type draft-ngram-mod` + `--rpc` — n-gram draft is built-in, no external model needed. +- **Supported:** `--spec-type draft-dflash` + `--rpc` — DFlash draft model loads locally via `--spec-draft-model`. +- **Not tested (assumed supported):** `--rpc` with the draft model on a remote node via separate `ggml-rpc-server`. + +**Limitation:** The draft model (`--spec-draft-model`) loads in the same process as the main model. If the main model is on a remote GPU via `--rpc`, the draft model typically needs to be local (on the main host's VRAM) or on an additional `--rpc` target. The RPC backend does not currently support routing draft-model forward passes to a remote RPC endpoint directly — draft inference runs on whichever GPU the `--spec-draft-model` file is mapped to via the tensor-split/RPC topology [5][7]. + +### 4.

The architecture uses a `ggml-rpc-server` binary that exposes local GPUs as RPC devices, while the main process connects via the `--rpc` flag. The RPC backend is currently a **proof-of-concept** that is **fragile and insecure**, with protocol version **5.0.0**. Both model weights and KV cache are distributed across all available devices (local and remote) in proportion to each device's free memory. Every node needs the **same GGUF model file and build/quantization**. Speculative decoding (ngram, MTP, DFlash, Eagle3) can be combined with RPC backends since the full model is visible to the main process. KV cache is distributed across nodes and `--ctx-size` applies globally. + +## Findings + +### 1.

Version Support and Build Requirements + +**Protocol version:** `RPC_PROTO_MAJOR_VERSION=5, RPC_PROTO_MINOR_VERSION=0, RPC_PROTO_PATCH_VERSION=0` + +**Build requirements:** Both the RPC server and the main client must be built with `-DGGML_RPC=ON`. The server binary name is `ggml-rpc-server`. The main client tools (`llama-cli`, `llama-server`, `llama-bench`) auto-detect RPC support and conditionally expose the `--rpc` flag. + +**GGUF quantization support:** The RPC backend is backend-agnostic — it forwards tensor operations to the remote backend (CUDA, ROCm, Metal, CPU, Vulkan, etc.). Any GGUF quantization that works on the remote backend will work over RPC, including: +- Q8_0, Q8_K (standard quantizations) +- IQ4_XS, IQ4_NL, IQ3_S, etc. (imquantizer formats) +- Q6_K, Q5_K, Q4_K (standard K-series quantizations) + +The RPC layer handles quantized tensor serialization natively — it does not require dequantization. Quantized tensors that need padding to 512 (CUDA backend) get the `RPC_CMD_INIT_TENSOR` call forwarded to the server. + +**Maximum RPC servers:** `GGML_RPC_MAX_SERVERS = 16` + +**Supported remote backends (any ggml backend works):** +- CUDA (NVIDIA GPUs) +- ROCm (AMD GPUs) +- Metal (Apple GPUs) +- Vulkan +- CPU +- SYCL (Intel GPUs) +- OpenVINO +- Any backend that implements the ggml backend interface + +**Version compatibility:** The HELLO handshake enforces that the client's protocol version is compatible with the server: +```cpp +if (response.major != RPC_PROTO_MAJOR_VERSION || response.minor > RPC_PROTO_MINOR_VERSION) { + GGML_LOG_ERROR("RPC server version mismatch: %d.%d.%d\n", ...); +} +``` +This means **major version must match** and **minor version must be >= on server**. + +### 3. Model File and Build Requirements + +**Every node needs the same model file.** The model is loaded once on the main host, and tensor data (weights and KV cache) is distributed across ALL devices in proportion to free memory. The GGUF file path is specified on the main host only. + +**Same build and quantization on RPC servers.** Each RPC server runs its own backend (CUDA, ROCm, Metal, etc.) and processes the same tensor types. Quantization is handled per-device — the main host sends tensors in their original GGUF quantization and the remote backend handles any necessary padding/alignment. + +### 4. Speculative Decoding Compatibility + +Speculative decoding **can be combined** with RPC backends. The speculative decoding infrastructure runs on the main host, and the full model (including both main and draft model weights) is distributed across local + RPC devices. Supported speculative types include: + +- `--spec-type ngram` / `--spec-type ngram-mod` — self-speculative decoding, fully compatible with RPC +- `--spec-type MTP` (Multi-Token Prediction) — requires draft GGUF, compatible with RPC +- `--spec-type DFlash` — DFlash speculative decoding, compatible with RPC +- `--spec-type Eagle3` / `--spec-type Eagle3-legacy` — Eagle3 speculative decoding, compatible with RPC +- `--spec-type DSpark` — DSpark speculative decoding, compatible with RPC + +**Key file paths:** +- `common/common.h` — `common_params_speculative` struct with all speculative types +- `common/arg.cpp` — speculative parameter parsing and model resolution + +**The speculative decoding works because:** +1. The main process loads both the main model and draft model +2. The graph computation (`RPC_CMD_GRAPH_COMPUTE`) handles all tensor operations including speculative tokens +3. RPC servers execute the full graph including speculative branches + +**Limitation:** The draft model is also split across the same device pool (local + RPC), just like the main model. + +### 5. KV Cache Distribution and Context Limits + +**KV cache is split across ALL devices** (local + RPC) in proportion to each device's free memory. The `--ctx-size` (or `--ctx`) parameter sets the global context length, and the KV cache is partitioned across devices based on available memory. + +**Key behaviors:** +- The main host loads the model and distributes tensors across all registered devices +- KV cache allocation follows the same proportional distribution logic +- No separate `--ctx-size-per-node` — context is global + +**No explicit --ctx-size limit specific to RPC nodes.** The total context length is limited by the combined KV cache memory of all nodes plus local memory. + +### 6. Known Limitations + +From `tools/rpc/README.md`: + +> **IMPORTANT:** This example and the RPC backend are currently in a proof-of-concept development stage. As such, the functionality is fragile and insecure. Never run the RPC server on an open network or in a sensitive environment! + +**Limitations table:** + +| Limitation | Details | +|------------|---------| +| **POC stage** | Functionality is fragile and experimental | +| **Insecure by default** | No authentication or encryption; never expose on open network | +| **Single model per connection** | Each RPC server connection handles one model instance | +| **Max 16 RPC servers** | Hard limit defined by `GGML_RPC_MAX_SERVERS` | +| **Synchronous graph compute** | `ggml_backend_rpc_graph_compute` is synchronous (no async ops) | +| **No cross-server tensor copy** | `ggml_backend_rpc_buffer_cpy_tensor` returns false if src and dst are on different servers | +| **Model weights sent per-request** | Tensor data is sent over the wire each compute step (not just during load) | +| **No RDMA on all platforms** | RDMA transport is Linux-only and requires `libibverbs` | +| **Quantized tensor padding** | CUDA backend pads quantized tensors to 512; RPC calls `RPC_CMD_INIT_TENSOR` to handle this | +| **Server model loading** | RPC servers load models on first request, not at startup | + +### 7. Benchmark Data + +The `llama-bench` tool supports RPC via the `-rpc` flag and can benchmark distributed inference. No published benchmark numbers were found for specific model sizes over 1GbE/2.5GbE/10GbE, but the architecture implies: + +- **Model loading:** Can be accelerated with the `-c` (cache) flag on RPC servers, which stores large tensors in `~/.cache/llama.cpp/rpc/` +- **KV cache traffic:** For each token generation, the full graph is serialized and sent to RPC servers (both K and V tensors) +- **RDMA benefit:** On Linux with RoCEv2 NICs, transport auto-negotiates RDMA for lower latency and higher throughput +- **Default 127.0.0.1:** The RPC server binds to localhost by default; warning shown when exposed to other hosts + +**Model weight transfer:** Quantized tensors larger than 10MB use FNV-1a hash-based cache on the server side (`HASH_THRESHOLD = 10 * 1024 * 1024`). If the hash matches, the server skips receiving the tensor data. + +### 8.

The service aborts +with `CUDA error: an unsupported value or parameter was passed to the +function` in `cublasSgemm_v2` at `ggml-cuda.cu:1541` during +`update_slots` -> `decode` -> `process_ubatch`. It crashed on 2026-08-13 +at 19:45 and 19:55 and on 2026-08-14 at 12:00:43. + +## What Was Ruled Out + +### ctx-checkpoints do not grow VRAM + +`--ctx-checkpoints 4` stores context checkpoints in host RAM. The log +records every checkpoint at exactly 62.813 MiB. The size never grows. +The reasoning: + +- `common_prompt_checkpoint` (common/common.h) stores the serialized KV + state in `std::vector` fields. These live on the host heap. +- `update_tgt()` and `update_dft()` call `llama_state_seq_get_data_ext` + with `LLAMA_STATE_SEQ_FLAGS_PARTIAL_ONLY`. The serialized state moves + from VRAM to RAM for the snapshot and back on restore. +- With 4 slots and `--ctx-checkpoints 4`, the maximum checkpoint RAM is + 16 x 62.813 MiB, about 1.0 GiB. That is fixed and small. +- `data_spec` (spec-decode state) is empty for ngram-mod. The ngram-mod + implementation does not override `get_state()`. + +### ngram-mod does not grow VRAM + +ngram-mod allocates one fixed 64 MiB CPU hash table +(`common_ngram_mod::entries`, 16M int32 entries). It never resizes. The +matcher keeps about 12 bytes per sequence. Draft generation runs on the +CPU. The speculative path allocates zero GPU memory. + +### The CUDA graph cache has eviction in this build + +`ggml_backend_cuda_context::cuda_graph()` sweeps every 5 seconds and +evicts graphs unused for 10 seconds. Upstream issue #25082 describes an +unbounded graph cache, but build b10108-13-g555881ebc includes the +eviction sweep. This build does not exhibit that leak. + +## What Grows + +### RAM growth is suspected, not yet confirmed + +systemd reported MemoryPeak 46.9 GiB for the crashed process and 45.9 +GiB for the replacement. RSS is flat at 32.3 GiB, which matches the +documented idle baseline of about 32 GiB. The difference is file-backed +page cache from the `--no-mmap` model read; cgroup memory.current counts +file pages attributed to the process. That gap is not proof of a leak by +itself. + +The upstream pattern to watch is issue #26216: the prompt cache and +checkpoint accumulation exceed the `--cache-ram` cap and do not plateau. +The environment file does not set `--cache-ram`, so the llama.cpp +default of 8192 MiB applies. The monitor logs RSS, which separates +anonymous memory from file cache. If RSS climbs under load while VRAM is +flat, the RAM-side accumulation is real. + +### VRAM suspects under load + +VRAM is flat at idle: 21,268 MiB across every monitor sample. The crash +correlates with load density and slot context size (143K tokens on +slot 2), not with wall-clock time. The two mechanisms worth testing: + +1. Flash-attention F16 K conversion workspace. The prefill kernel on + Ampere is `MMA_F16`. It converts the quantized K cache (q8_0) to F16 + for the attention math. The workspace size scales with the attended + context length (`ggml_nelements(K) x 2`). It is allocated into the + graph buffer via `ggml_cuda_flash_attn_ext_get_alloc_size`. +2. The CUDA VMM pool grows monotonically. `ggml_cuda_pool_vmm::alloc` + only reserves more physical memory; `free` only releases the + reservation slot. The pool never shrinks during the process + lifetime. Any new peak allocation permanently expands VRAM usage. + +Both match the observed pattern: growth under prefill bursts at deep +context, flat at idle, crash when a burst exceeds the ~2.8 GiB headroom. + +## Monitoring + +The monitor runs on Dankserver: + +``` +/home/dank/vram-monitor.sh +/home/dank/vram-log.csv +``` + +It samples GPU VRAM and process RAM every 10 seconds and appends a CSV +row. The columns are timestamp, uptime, GPU VRAM MiB, GPU utilization, +process RSS, process VSZ, and systemd MemoryPeak. + +## Mitigation Options + +The documentation for the benchmark ([[frank-default-small-benchmark]]) +prescribes the first option for this crash class.

The per-token transfer is ~41 KiB (5120-wide f32 hidden state, both +directions); at ~0.5 ms LAN RTT the bandwidth cost is negligible — the split +is latency-bound, not bandwidth-bound (see +[Ethernet Bandwidth Math](Pipeline%20Parallelism/Ethernet%20Bandwidth%20Math.md)). + +Why this is a real speedup and not just "two GPUs": the 3090 does +matmuls roughly 2–3× faster per layer than the 8060S (936 vs 512 GB/s +memory, 80 vs 40 CUs).

The kernel log showed bursts of `amdgpu: SVM mapping failed, exceeds resident system memory limit`, which pointed at memory but was a red herring. +On 2026-08-13 the old `frank-default-large` service crash-looped for hours on Dankclaw. Root cause: the env files exported `TEMP=1.0` (a sampling default). The ROCm HIP runtime reads `TEMP` as its JIT kernel-cache directory, used the path `1.0`, failed, and segfaulted on a NULL object. Fix: rename the sampling variable to `TEMPERATURE` (commit `227ce01`). -Root cause: the env files exported `TEMP=1.0` (a sampling default added in commit `db3eb01`).

The suspicion was speculative decoding. The investigation found three facts: - -1. **The server does not preempt.** `llama-server` defers a new task into a queue when all slots are busy. It never releases a running generation to make room. Verified empirically with concurrent streaming jobs. -2. **The releases were client-side aborts.** The pi coding agent aborts a stream when the user interrupts it. The client records `stopReason: "aborted"`; the server logs `W srv stop: cancel task, id_task = N`. A natural stop (EOS or limit) logs only `slot release` with `truncated = 0`. -3. **Dankserver crashed under the parallel researcher load.** Five parallel research subagents hammered `frank-default-small` with back-to-back requests. The service aborted twice with `CUDA error: an unsupported value or parameter was passed to the function` in `cublasSgemm_v2` at `ggml-cuda.cu:1541`, then `status=6/ABRT`, then `503 Loading model` for ~5 minutes. That crash, not speculative decoding, killed the parallel jobs. The affected service is retired; see [[dankserver-vram-growth]] for the VRAM/RAM growth findings behind the crash class. +Historical: on the retired topology, parallel jobs on the Dankserver 35B service died with a cuBLAS crash under researcher load.
