Issues
- #1495 [Feature]: experimental per-stage KV-grow for a two-GPU layer split at native 262K
- #1488 prefill.cpp: a GCC 10 build fails (std::atomic::wait is a GCC 11 library feature, with no guard and no documented minimum)
- #1487 Windows/CUDA 11.8 Volta integration: focused patches and reproducible handoff
- #1485 [Bug]: update.sh cannot rebuild a locally compiled engine on a PC with a Volta card beside an RTX 40 (nvcc: Unsupported gpu architecture 'compute_70')
- #1484 [SYCL] 2x Arc Pro B70 + UD-IQ4_XS: the port's default expert kernels give corrupted output (silent wrong answers); STRATA_EXPERT_SPLIT=1 restores it
- #1483 Local-adaptation tuning directions (method, not values) — plus the hardware-specialization layer (model → GPU → CPU) that I'm building
- #1482 [Feature]: publish a ready-made Docker image, so users do not compile the engine themselves
- #1479 HIP: STRATA_HEAD_MIX_MULTI / STRATA_ONE_TOKEN_COMMIT are hard-off; as opt-ins head-mix is exact and +0.4% decode on R9700 (patch inside)
- #1475 expert_cache_segmented_test fails on HIP builds instead of skipping (--vram-elastic is CUDA-only)
- #1474 hip_q2_zero fails on gfx1201 (R9700) with ROCm 7.10: Q2_0 signed-zero fix e9a5f8d is gated to gfx1012 / HIP < 7
- #1470 Pascal (sm_61): decode halves since 0.1.40.2. 2e4ddf6 drops `__restrict__` and peels the MMVQ loop on every CUDA arch
- #1469 0.1.40.2: decode on a Tesla P40 (sm_61) is about half of 0.1.40's; bisected to 2e4ddf6, and restoring __restrict__ in pdl.hpp (STRATA_PDL_RESTRICT) gives back most of it
- #1468 prefill copy_i32: illegal memory access on long prompts when the prefill chunk is large (auto:32768)
- #1447 docs: MULTI_GPU.md says --pipeline-windows 2 and --adapt-async 1 exclude each other, but they combine
- #1445 vision encoder did not start on V100-SXM2-32GB
- #1442 Feature request: support chat title generating from Xcode's agent
- #1440 [Bug]: [SYCL] 0.1.40.2 on 2x Arc Pro B70: --layer-split fails three ways (#1054's fix from #1111 is not in main, plus two new split regressions)
- #1431 Feature request: tool-call emission recovery for low-bit quants in agent workloads (Qwen3.8-Flash-Next GSQ-RCO IQ3_XXS)
- #1428 --layer-split auto on a P40 + RTX 3070 (3070 first) flips from K=43 to K=47 with --kv int8 or --vram-reserve-mib 600, and prefill drops from 458 to 111-113 tok/s (0.1.40.2)
- #1425 [Windows, RTX 5090 32 GB, NVFP4 fork] ple: --ple-io direct streams the n-gram table at ~34 MB/s while the SSD does 1.4 GB/s - fresh long prompts prefill ~5x slow; cold passes can trip the #29 watchdog
- #1412 Windows: `SeLockMemoryPrivilege` moves the expert arena to 2 MiB large pages — but the token is issued at logon (1314 ≠ 1450)
- #1410 Support Intel Arc Pro B50 (Xe2 / BMG-G21) as a tested SYCL target — 16 GB at 70 W is the card users are actually buying
- #1404 [Feature]: run the image encoder on a second PC
- #1386 2x RX 7900 XTX (gfx1100, layer split): STRATA_PF_GEMM is worth ~7% prefill and is off by default
- #1385 Intermittent 'int' object has no attribute 'ranks' in tokenizer
- #1373 Windows, 2-GPU layer split: 0.1.40.2 decode is 20% below 0.1.39 across the board, and STRATA_MMVQ_IL is 15% of it
- #1369 Two 32K prompts on one RTX 5090: overlapping them matched back-to-back wall time

- #1352 Multi-GPU performance is ~2x lower than Francesco Albano fork despite the changes being merged into v0.1.40
- #1349 2× RTX 2080 Ti (Turing, NVLink) field report: DDR4-2666→3600 memory A/B, own vs borrow vs peer-device by context size, three-switch stack
- #1348 Foresight: fetching MoE experts before they're needed — measured on 2× 3090 (update: prefetch path built and correct, no decode gain yet; data, tools, help wanted)
- #1347 serve: a full conversation cache drops the snapshot at the physical-RAM gate instead of evicting to pass it (270k tokens re-read, 96 s, 32 times)
- #1341 serve: a >100k-token prompt deadlocks the pipelined verify-window reader (--pipeline-windows >= 1) - the #29 watchdog aborts the engine and the server reloads the model
- #1337 setup --calibrate loses the measurements it already has when a later engine start fails
- #1322 setup re-run with --vision gpu does not add --vision to an existing config's args
- #1317 serve: an untimed read of the engine/vision pipe can hold the request turn forever (intermittent hang; the #481 lost-step class)
- #1312 [Windows][RTX 3090 24 GB, 64 GB RAM, IQ3_S] Feature request: expose the QSA indexer budget (512 blocks / 2048 tokens)
- #1302 0.1.40 SYCL port on 2x Arc Pro B65: expert-cache fill stalls (1-core spin + xe "Timedout job" + device coredump); 0.1.38-based engine works on the same card
- #1301 docs: `--lookup-chain` — note the workload it targets (repeating context), since the default suffix path already covers non-repeating text
- #1300 bench: community report, 2x Tesla V100-PCIE-32GB (sm_70, CUDA 12 source build): IQ3_S at 512K with --layer-split, and what the new decode profiler says about where tok/s comes from

- #1250 [Linux][RTX 3080 12 GB, 62 GB RAM] 0.1.40.1 start OOMs the host while allocating the page-locked expert copy (IQ2_XS); 0.1.31 starts fine
- #1248 SYCL build fails on Intel Arc A770 (Alchemist) - v0.1.40.1
- #1244 Docker v0.1.40: persisted /data/config edits ignored on restart; stale /opt/strata config used (worked in v0.1.39)
- #1239 v0.1.40 two-GPU tester results on a P40 + RTX 3070: 150-request soak clean, --pipeline-windows 2 +9% / +15% decode in 5 of 5 pairs
- #1238 0.1.40: --layer-split auto with STRATA_STAGE_TRIM=1 still picks K=2 on a P40 + RTX 3070; 572b607 fixes it but is not in the release
- #1235 Sapphire Rapids (Xeon w7-2475X): +8% decode, +3% prefill and byte-identical greedy output. STRATA_IQ_MT_MIN=1 is faster here, and 8 stager threads beat 32
- #1234 Windows/RTX 4090 (0.1.39): stall report stage "decode -1" for 61 s; 0 layers served - thread stacks attached

- #1194 `file_cache_keeps()` picks unbuffered (O_DIRECT) expert reads on a 32 GB + 12 GB GPU box with `--resident-budget-gib`, halving decode; `STRATA_UNBUFFERED_LOAD=0` restores it
- #1188 --kv k8v4 produces degenerate repetition when --kv-resident streams (0.1.40)
- #1180 STRATA_PF_FUSED on gfx1100: missing __syncthreads() in native_w11_kernel + waves_per_eu(8) wrong on clang 22 / ROCm 7.10
- #1169 k8v4 + --kv-resident: the batched KV append (#783) skips the host mirror for hybrid — parking and KV streaming serve stale bytes (cross-conversation contamination on 0.1.40)
- #1168 Client-supplied stop sequences are ignored (OpenAI `stop` and Anthropic `stop_sequences`) — blocks agent/harness use
- #1165 Ship an MMQ-enabled engine build (or opt-in loading) for k-quant prompts: a full-RAM machine is GPU-bound on the FP16 dequant path
- #1155 [Windows / AMD] --vision cpu is still unreachable: hip_vision()'s WIN gate, find_vcvars()'s VS-18 range, and no encoder in the ready-made engine
- #1153 [Volta] STRATA_GDN_CHUNK=1 (PR #1098 chain-split) segfaults the engine on a 4-GPU layer split (4×V100)
- #1145 Resident RAM mode on a layer split — 3 GPUs, UD-IQ4_XS, 40 GB RAM (engine 0.1.40)
- #1143 Tester report (2× RTX 2080 Ti, Turing): #743 prompt A/B, #776 batch soak, #859 pipeline-windows, #848 resident soak — all pass

- #1135 k8v4: deterministic token repetition on sequential generation (RTX 5090, 0.1.40) — byte-identical across two quants
- #1128 0.1.40 --kv-grow: a short request trims the K/V to 8192 cells and drops the conversation cache, so the next 128K+ continuation is re-read in full (20.9% of continuations, RTX 5090, IQ3_S)
- #1121 --batch-mtp kills the engine on an IQ3_S (GSQ-RCO) pack: mtp: unsupported native MMVQ GGML type
- #1118 Batch slots: the engine stalls ("no progress for 60 s … reading the prompt (batched)") when a long prompt is read while another slot decodes; STRATA_BATCH_DECODE_SHARE=0 avoids it

- #1074 Build fails on openEuler 24.03 / GCC 12.3 (sm_70): vmm.hpp uses an unqualified size_t
- #1071 vmm.cpp: the CUDA 12 engine does not build with a toolkit older than 12.5 (missing CUDART_VERSION guard)
- #1069 Tesla P100 (Pascal, sm_60) + RTX 2070 SUPER, Linux/Docker (CUDA 12.9), 32 GB RAM: Q2_0 low-RAM mode, about 30 tok/s decode on the P100 alone and 36-38 tok/s with the second card as a helper expert cache (benchmark.py)
- #1059 serve: a request the engine rejects with ERR waits the full 300 s before failing (STOP + _drain_control("DONE") after an ERR), holding the control lock
- #1058 0.1.40: a tool call quoted in the thinking is delivered as a real call (fires on a max_tokens cut and inside code fences)
- #1056 Prefill: Stager threads yield-spin while waiting. On Linux with --mmap-experts (DGX Spark / GB10), prompts are read ~10x slower; elsewhere ~20 cores are burned during prefill
- #1054 [SYCL / Intel Arc] 2x Arc Pro B70 --layer-split auto deadlocks at startup after the host-mirror fill

- #1012 0.1.39 serve: after an engine restart, waiting requests hang forever or fail with "list.remove(x): x not in list"
- #1009 8 GB card: 0.1.39's default prefill is ~40% slower than 0.1.31 (prompt chunk 512 -> 256 when borrowing cache slots)
- #1005 CRLF line-break tokens (`\r\n`, ids 317/845/8301) get far too little probability; everything else matches llama.cpp
- #997 0.1.39: engine exits (code 1) with "parallel": 4 on UD-IQ4_XS, RTX 3090 24 GB, three concurrent 8K prompts (reproducible; IQ3_S unaffected)
- #985 Also allow Visual Studio 2026 to build from source
- #980 Field report: local Qwen3.8-Flash-Next (Strata) as an agent building 3D scenes in Unreal Engine 5.8 via MCP — what broke, what fixed it, what is still missing
- #977 --check prints [ok] for below-floor RAM and a misleading 'This PC can run Strata' verdict
- #971 Report: UD-IQ4_XS with images works (0.1.39, NVIDIA L40S vGPU in a VM, driver 550 / CUDA 12)
- #968 0.1.39: UD-IQ4_XS prompts read as garbage on an RTX 5090 (sm_120) through the MMQ prompt path; STRATA_PREFILL_MMQ=0 or an sm_86 card reads them correctly

- #959 ./setup.sh fails on Gentoo Linux
- #954 [BUG] 0.1.39: fused int8 prompt experts (STRATA_PF_FUSED=1) + #583 byte-budget ring → kernel hang, `prefill mmq: iota: unknown error` on sm_120 (RTX 5090, WSL2)
- #952 BrokePipeError when terminating Strata on Linux
- #942 AMD `gfx1102 / RX 7600 XT` - successful real model run on Strata 0.1.39
- #941 UPD: Successfully run on RTX 3090 24gb + Z590E + 64gb ddr4 3200 2ch
- #929 `--batch` with `--layer-split` exits ("verify batch: layer 34 never rang") with a 3070 first and a P40 second; works with the P40 first (CUDA, v0.1.39)

- #918 Windows: Radeon 8060S (gfx1151) builds, selftests and passes the HIP ctest on top of #895
- #916 Unable to launch Strata on RTX 2060 6GB VRAM + 32 GB RAM

- #884 HIP gfx1030, 2x RX 6900 XT: verify hangs after a long prompt when MMQ prompt path, adaptive expert swaps and SDMA meet (any one off avoids it)
- #881 [Windows / AMD] RX 6800M (gfx1031) runs with a self-built HIP engine — plus 2 Windows bugs found (packaging encoding, vision `vcvars`)
- #879 All-logits-NaN degeneration (one repeated token forever) still fires on 0.1.39b / current main — first poison traced to the MoE output rows: garbage bits, varying layer
- #875 P40 + 3070 (mixed Pascal/Ampere pair): `layer_split: auto` vs forced splits on 0.1.39, with hit rates (follow-up to #604)

- #498 setup: offer the layer split (`--gpus`) for UD-Q4_K_XL when the GGUFs fit in RAM — the engine already runs it without the budget (2x RTX 3090: 31 → 64-78 tok/s)
