LuxiEdge / Research and measured work
A result is only as broad
as its test.
Explore inference, quantization, numerical primitives, risk, orbital computation, genomics, atmospheric science, and memory-movement research. Named measurements are evidence. Unmeasured applications and proposed capabilities remain research directions. Neither establishes universal production readiness.
01 / Inference
Prompt processing and generation are different tests.
Measured / internalCurrent Qwen2-7B-Instruct evidence compares named vLLM and SGLang normal and deterministic modes on H100. It separates output repeatability, reference checks, throughput, and GPU-board energy.
Luxi logits and token-sequence hashes repeat across the tested conditions. Top-token and ordered top-5 reference agreement does not establish full-sequence identity with Hugging Face; published greedy sequences include divergences. Normal-mode generation has different speed and energy tradeoffs from deterministic-mode generation.
02 / Quantization
Representation needs its own evidence.
Research direction / no specific result claimedReduced precision and quantized representations need explicit rounding rules, a reference, and quality acceptance criteria. Repeatability alone would not prove model quality.
No specific quantization quality, compression, speed, or energy result is asserted here. The published inference comparisons are not a substitute for a quantization evidence pack. A proposed evaluation must define the representation and computation before making a claim.
03 / Numerical primitives
Check the reference, not just the hash.
Measured / synthetic inputThe GPU-sum report compares stock float32 reductions with a correctly rounded exact total. Stock repeatability and numerical correctness are separate questions.
The published Luxi exact-path hash matches on the tested L4, x86, and Apple arm64 paths. This fixed-order correctness path is distinct from the faster chunked reduction. The synthetic positive input and single GPU model do not establish universal accuracy or platform support.
04 / Risk
Public catastrophe tests are not a runtime release.
Measured / public Oasis artifactsOrdinary PiWind reruns test output stability. A separate synthetic extreme-TIV stress case checks ground-up totals against an exact reference. The two checks are not interchangeable.
The public stock-drift report records model scope, worker conditions, environments, hashing, and reproduction commands. It makes no speed or energy claim. The ordinary PiWind values were not exact-reference checked; the stress test does not validate every output or a customer book.
Customer pricing, market data, scenarios, and methodology remain controlled by the customer. Authoritative rebuilds remain comparators and reconciliation mechanisms.
05 / Scientific and orbital
Named grids. Serialized states.
Measured / named SGP4 gridsPublic SGP4 artifacts compare serialized Luxi states across tested platforms for the jax100 and starlink-382a419 grids. Reference comparisons are separate from the state-byte test.
The reported state bytes match across macOS arm64, Linux arm64, qemu Linux x86_64, and H100 on those grids. The H100 build is near-earth only, and the x86 result is emulated, not a native-host test. Rejected starlink states are recorded as NaNs.
06 / Atmospheric science
Kessler microphysics
Measured / named LAFT inputsThis study asks whether the same warm-rain calculation returns the same bytes on different hardware. It uses public float64 inputs from NSF NCAR’s LAFT work, credited to Linck, Dennis, Schreck, Stengel, and Gagne.
With identical float64 LAFT inputs, Luxi produced bit-identical output hashes across Intel Xeon, Apple M1 Pro, and NVIDIA A100 at nine tested sizes from 50 to 100,000 columns. In the same-pod A100 comparison, Luxi was 1.9× to 11.5× faster than the published Gemini JAX translation across the reported GPU timing sizes, including the GPU-only million-column case.
Additional evidence / scientific breadth
Different studies. Named boundaries.
These studies are published with their workload, hardware and limits.
Genomics / separate research effort
Deterministic-PairHMM
Measured / 17 June 2026Stable aggregate haplotype scores let researchers check whether changing parallel execution changes the recorded result. This separate study used public GIAB HG002 MHC reads on CPU and NVIDIA H200.
The published result is fingerprint stability across the tested CPU thread counts and GPU block sizes. It concerns aggregate PairHMM scores on the recorded workload, not a universal genomics result.
Supporting orbital study
SAAL comparison
Measured / named catalog gridThis comparison separates run-to-run repeatability from agreement between platforms. It compares SAAL, python-sgp4, and Luxi SGP4 on a public 15,940-object catalog over a 24-hour grid.
The grid starts at 12:00 UTC on 11 October 2026; the summary does not specify a separate measurement date. The CPU environments include Linux x86_64, Linux arm64 under qemu, native macOS arm64, and a Mac Intel binary under Rosetta 2. Each engine repeated on its own platform; the reported SAAL cross-platform differences were micrometres, not evidence of inaccuracy.
Supporting orbital study
OrbVeil catalog evidence
Measured / 11 October 2026A catalog-scale check asks whether the same orbital inputs produce the same recorded state bytes. The study used the CelesTrak active catalog of 15,940 objects over a 24-hour grid, comparing Luxi with python-sgp4.
Luxi’s recorded hash matched on Apple M1 Pro/macOS, a native Linux arm64 container on that Mac, and qemu Linux x86_64. Stock python-sgp4 repeated within each platform but its hashes differed between these platforms. This is a result for that catalog and grid, not universal orbital accuracy.
Memory movement / historical research
AttentionTransformer V2
Historical snapshots / June and July 2026Memory movement can matter as much as arithmetic in attention workloads. The attention-v2 evidence records named attention, stack, and memory-scaling fixtures rather than a general model-serving result.
The public snapshots cover H200 research from June 2026 and an H100 suite dated 11 July 2026. They include an H200 16k rag_tokenized compressible-KV fixture, H100 stack comparisons, WNSM measurements, and long-context memory scaling. PyTorch Flash won the H100 short-sequence same-shape comparison.
Sources / inspect before extrapolating
The public source index.
Pin the repository commit you inspect. Public checkers and raw artifacts support verification and recomputing reported summaries; they do not supply the proprietary benchmark engines.
Read the limits before choosing a workload.
Each family needs its own contract. Output hash equality is not an accuracy check; one hardware result is not a universal support promise; one measured path is not end-to-end deployment evidence.
