Llama-3.1-8B-Aurora-Chat v3

🏆 Best Aurora chat model in our zoo (eval 2.80/5, +59% over base).

LoRA fine-tune of meta-llama/Llama-3.1-8B-Instruct specialized for the ALCF Aurora supercomputer (Intel Xeon Sapphire Rapids + Intel GPU Max 1550 / Ponte Vecchio, oneAPI / SYCL, PBS Pro).

Off-the-shelf code-LLMs hallucinate Aurora specifics — they suggest nvcc instead of icpx -fsycl, srun / aprun instead of mpiexec, NERSC's /global/cfs instead of /lus/flare, and CUDA device strings instead of xpu. This adapter teaches the base model the actual Aurora toolchain, file system layout, scheduler conventions, and recommended PyTorch/TensorFlow/SYCL idioms.

Precision / seq-len	bf16, 1,536 tokens
Training data	aurora-docs-distill-multirank — 4,495 ChatML rows
Train loss (final)	0.6224
Hardware	1 Aurora PVC tile (1/12 of a node, 64 GB HBM), IPEX + PyTorch 2.10 XPU backend
Eval (53-Q Aurora, 0–5)	2.80 / 5   (base 1.76, +59.1%)

Quick start

On Aurora (PVC GPU, SYCL llama.cpp build) — interactive PBS session:

# 1. Grab a debug node
qsub -I -A <project> -q debug -l select=1,walltime=01:00:00,filesystems=home:flare

# 2. Load the toolchain
module load frameworks
source /lus/flare/projects/<project>/scripts/env.sh   # or your own oneAPI setup
export ONEAPI_DEVICE_SELECTOR=level_zero:gpu

# 3. Download to flare (NOT $HOME — quota is small)
hf download shazzadulimun/llama31-8b-aurora-chat-v3-gguf --local-dir /lus/flare/projects/<project>/models/aurora-chat-v3

# 4. Run on a single PVC tile
/path/to/llama.cpp/build_sycl/bin/llama-cli \
    -m /lus/flare/projects/<project>/models/aurora-chat-v3/*.gguf \
    -ngl 999 -sm none --temp 0.0 -cnv \
    -p "How do I launch one MPI rank per GPU tile on Aurora?"

Anywhere else (laptop, workstation, any GPU):

hf download shazzadulimun/llama31-8b-aurora-chat-v3-gguf --local-dir ./model
./llama-cli -m ./model/*.gguf -ngl 999 --temp 0.0 -cnv

Or Ollama / LM Studio: ollama run hf.co/shazzadulimun/llama31-8b-aurora-chat-v3-gguf

Training data

Distilled from openai/gpt-oss-120b on ALCF Sophia (vLLM) over 416 cleaned chunks of docs.alcf.anl.gov/aurora. 4,495 training rows + 562 validation rows in ChatML format with embedded chain-of-thought (**Reasoning:** / **Answer:**).

Broad coverage, parallel-rank distillation. 20 worker ranks each took a disjoint slice (~21 chunks) of the cleaned docs.alcf.anl.gov/aurora corpus and asked the teacher for chain-of-thought QA pairs. Disjoint slicing maximizes phrasing diversity (each rank sees fresh context) while still covering every chunk exactly once.

Evaluation

53-question Aurora-domain holdout (programming models, ML/AI, systems/ops, debugging). Judged by gpt-oss-120b on a 0–5 scale.

Model	Avg	Δ vs. base
Llama-3.1-8B-Aurora-Chat v3 (-A data) — best	2.80	+59%
Llama-3.1-8B-Aurora-Ops v3	2.31	+31%
Llama-3.1-8B-Aurora-Chat v1 (-B data, single-rank ablation)	2.45	+39%
Llama-3.1-8B-Aurora-ML v3	2.13	+21%
Llama-3.1-8B-Aurora-Coder v3	1.97	+12%
meta-llama/Llama-3.1-8B-Instruct (base)	1.76	—

Closed frontier models (gpt-4o, claude-sonnet-4-5, the gpt-oss-120b teacher) score 3.6–4.1 on the same holdout — the goal here isn't to beat them, it's to distill enough Aurora knowledge into a small open model that runs on a single PVC tile.

Limitations

• Synthetic-data biases. Teacher (gpt-oss-120b) can confabulate plausible-looking but incorrect commands. Treat outputs as a verifiable first draft, not authoritative.
• Doc snapshot is fixed at 2026-04-29. Module versions, queue names, and APIs change — anything published after that date isn't reflected here.
• Aurora-only. Specifics (/lus/flare, xpu, PBS queues) won't transfer to Frontier, Polaris, or other systems.
• Use temperature ≤ 0.1 for technical answers; higher temps invite invented flag names and paths.
